AC vs DC Power: All the Pros and Cons for Your Business Needs
Thanks to the marvels of our constantly advancing and eternally impressive technological advancements, flicking on a light switch or plugging in a laptop is even simpler than primitive tasks like combing your hair or putting on clothes.
But when you’re in business, power is even more useful than keeping the lights on. A stable, reliable supply of electricity keeps your operations safe and productive, keeps you in touch with your customers, streamlines your operations, and keeps those profits flowing as consistently as the power to your computers, machines and premises.
Digging a little deeper, though, reveals the true marvel of power. Because while the power to your power-points is AC, the power delivered to your computers, phones and other electronic devices and equipment is much more likely to be DC. Why’s that? What’s the difference? And why does it matter for your business?
Let’s dive in:
AC versus DC
If your knowledge of AC/DC extends a little further than the rock’n’roll band, let’s start right from the beginning: the difference between the acronyms.
AC stands for alternating current, which can both change direction and magnitude, while DC is direct current – an electrical charge that is one-directional.
Thomas Edison famously pioneered DC, but it ultimately proved difficult to convert into either the lower voltages required for the end-user.
Luckily, Nikola Tesla was busily experimenting with AC, which ‘alternates’ multiple times with each blink of the eye – and the rest is history.
In fact, the power supplied to every home and business across the world runs on the Tesla principle, which is generally understood to be an easier and more reliable way to transmit power across long distances.
DC, though, is easier to manage and store locally, especially with the delicate workings and ultra-thin wiring of most applications and devices familiar with the DC power connectors you use both at home and work.
AC: The pros and cons
As well as being better for transmitting electricity from its source to the user, AC power is easily ‘stepped up’ or ‘stepped down’ from lower or higher voltages, including the more stable and precise DC requirements of most of the devices we use power for. AC generators and motors are also quite significantly simpler and cheaper than their DC counterparts.
However, despite the simplicity and the other benefits, AC tends to interfere with other communication lines, including harmonics problems that electrical operations that are erratic and difficult to diagnose and remedy.
DC: The pros and cons
Transmitting DC power requires only one or two smaller conductors, and there are also fewer issues in terms of capacitance, phase displacement, inductance and even power surging. That means less insulation is needed for the same voltage as AC, while interference with other systems is also lower.
However, DC voltage is unable to be ‘stepped up’, unlike the much more versatile AC. In practice, that means a 240-volt device requires DC power delivered at precisely 240 volts, with any additional resistors or instruments to reduce the voltage only complicating the arrangement and wasting energy in the process.
Why it matters for your business
In a nutshell, that’s essentially why your business may be in the market for a DC power connector, which enables your small to medium devices to receive the precise power requirements via the AC source.
As a result, there are countless DC power connectors out there to enable safe, secure, efficient and reliable energy for your business needs, so talk to an expert today to match the right choice to your precise requirements.

The Nigerian Education Loan Fund (NELFUND) has granted another extension for its Student Loan Application Portal to accommodate institutions that requested additional time for the 2025/2026 academic session.
According to the statement signed by NELFUND’s Director of Strategic Communications, Ms Oseyemi Oluwatuyi, on Thursday, the extension applies only to institutions that submitted formal requests, allowing eligible students extra time to complete their applications.
“The Nigerian Education Loan Fund has approved an extension of its Student Loan Application Portal for institutions that have formally requested additional time for the 2025/2026 academic session,” the statement read.
Business Post reports that at the beginning of March, NELFUND announced an extension to the deadline by a week for its student loan application portal following a notable rise in nationwide interest driven by ongoing awareness campaigns.
Speaking on the development, NELFUND Managing Director and Chief Executive Officer, Mr Akintunde Sawyerr, reiterated the Fund’s commitment to ensuring that eligible students at participating institutions can access the student loan programme.
“NELFUND remains committed to ensuring that eligible students across participating institutions have the opportunity to access the student loan programme,” he said.
The Fund urges students in affected institutions to take advantage of the extension and submit their applications through the official portal.
It also emphasised its dedication to transparency, accountability, and providing sustainable financing solutions to remove financial barriers to higher education in Nigeria.
Established to administer the Nigeria Student Loan Scheme, NELFUND was enacted into law by President Bola Tinubu in April 2024.
The initiative provides interest-free loans to students in public tertiary institutions to cover tuition and living expenses.
Beneficiaries are required to repay the loans after completing their education and securing employment, aiming to increase access to higher education for students from low-income backgrounds.

The Nigeria Revenue Service (NRS) has inaugurated a Curriculum Review Committee aimed at strengthening taxation education in Nigerian academic institutions and improving the country’s tax administration system.
According to a statement, the committee was inaugurated on February 24, at the NRS Academy in Durumi as part of the agency’s broader efforts to modernise tax education and align academic training with the evolving demands of contemporary tax administration.
Speaking during the inauguration, the Director of the NRS Academy, Mr Adeolu Akinyemi, said the review exercise would involve collaboration with the Chartered Institute of Taxation of Nigeria (CITN) to develop a more structured and relevant curriculum for the academy.
He emphasised that the initiative seeks to ensure that taxation programmes taught in Nigerian institutions reflect current developments in tax policy and practice, while also equipping students with the practical knowledge required in today’s tax administration environment.
The committee has been tasked with examining existing taxation curricula across Nigerian institutions and proposing updates that incorporate modern tax policies, recent legislative changes, and emerging areas such as digital taxation and global tax practices.
Officials say the review is also designed to close the gap between theoretical classroom instruction and the practical realities of tax administration.
By strengthening the link between academic learning and professional practice, the revised curriculum is expected to better prepare graduates for careers in the tax sector.
The effort is further expected to enhance tax awareness among citizens, encourage voluntary tax compliance, and support the development of skilled tax professionals who can contribute to national revenue generation and economic growth.
The committee is chaired by Mrs Aisha Hamman Mahmoud, Special Adviser to the Executive Chairman of the NRS on Research and Statistics. Its membership includes representatives from the service as well as academic experts in taxation and fiscal policy, alongside professionals with experience in tax administration, policy formulation, and tax education.
The committee will work with relevant educational regulatory agencies and professional bodies to ensure that the proposed curriculum aligns with national academic standards while addressing the practical needs of Nigeria’s tax system.
The NRS stated that the initiative forms part of its ongoing commitment to expanding tax knowledge, strengthening professional capacity, and promoting responsible tax practices across the country.
The curriculum review exercise is expected to be completed within 60 days, after which the Service plans to provide further updates on the implementation of the revised programme.

The first batch of Nigerian undergraduates to enjoy fully paid scholarships for studying science, technology, engineering and mathematics (STEM) courses across the continent has been chosen by Airtel Africa Foundation.
Business Post gathered that 70 students from universities across Nigeria were selected from thousands of applicants through an independently managed process, which took nearly six months.
It was learned that most of the undergraduates were from the University of Lagos (UNILAG), Obafemi Awolowo University (OAU) Ile-Ife, the University of Benin (UNIBEN), Tai Solarin University of Education (TASUED), the University of Ilorin, Ahmadu Bello University (ABU Zaria), and the University of Nigeria (UNN).
The scholarship covers tuition, laptop computers, living expenses, and essential learning resources, a statement from Airtel Africa Foundation disclosed.
The chairman of the foundation, Mr Segun Ogunsanya, speaking at the presentation of the scholarships to the beneficiaries at the Lagos headquarters of Airtel Nigeria, emphasised the need for initiatives such as the Airtel Africa Foundation’s undergraduate tech scholarship for the future of the continent.
“True legacy is not measured by the awards we win or the volume of SIM cards we sell; it is measured by the lives we save, the people we feed, and the students we support when the line between success and failure is at its thinnest.
“At the Airtel Africa Foundation, we believe that lifting people out of poverty is the ultimate benchmark of a great company. Today, we are writing that legacy by tilting the balance in favour of the brilliant but underserved, ensuring that the fourth industrial revolution, driven by AI and Data Science, is built by African talent for the African continent,” he stated.
Mr Ogunsanya further revealed that this fellowship, executed through Airtel Nigeria, is designed to bridge the gap where funding, skills, and opportunity often fail to meet.
In addition to the N500,000 yearly budget for the fellows’ four-year or five-year courses, each fellow would be integrated into a structured support system for academic guidance and career mentorship, intended to ultimately transition students from the classroom to the global tech workforce.
Addressing the students, the chief executive of Airtel Nigeria, Mr Dinesh Balsingh, stressed that youth development is a strategic imperative for Airtel.
“At Airtel Nigeria, we view youth development as essential nation-building. When young people succeed, innovation accelerates, and social stability improves.
“By connecting these brilliant scholars to knowledge, skills, and confidence, we are fulfilling our core mission to connect people to opportunity. To our recipients: you earned your place here through merit and discipline. You are now ambassadors of excellence, and we expect your leadership to be defined by your conduct as you help shape a more inclusive digital future for Nigeria,” the Airtel Nigeria chief said.
The Nigerian cohort joins a prestigious network of Airtel Africa Foundation fellows currently studying in Tanzania, the Democratic Republic of Congo (DRC), Uganda, and India.
The initiative underscores a broader commitment to technology education, youth development, and Nigeria’s digital economy.
