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.

Tinubu Renames PTDF College After Shehu Musa Yar’Adua
By Adedapo Adesanya
President Bola Tinubu has approved the renaming of the Petroleum Technology Development Fund (PTDF) College of Petroleum and Energy Studies, Kaduna, in honour of the late statesman, General Shehu Musa Yar’Adua, in a move aimed at preserving his legacy while strengthening Nigeria’s specialised energy education framework.
The PTDF announced that, following a presidential directive, the institution will now be known as the General Shehu Musa Yar’Adua University of Geological Sciences and Engineering Technology.
In a statement, the Fund said the renaming reflects the federal government’s recognition of Yar’Adua’s contributions to national unity and Nigeria’s democratic evolution.
The late statesman, who died in 1997, was a prominent Nigerian soldier, politician, and businessman. He served as the Chief of Staff, Supreme Headquarters, under General Olusegun Obasanjo’s military administration from 1977 to 1979. He was the elder brother of former Nigerian President Umaru Musa Yar’Adua.
“This historic renaming honours the enduring legacy of the late statesman, General Shehu Musa Yar’Adua, celebrating his profound contributions to national unity and the democratic journey of Nigeria,” the PTDF stated.
The institution, established to develop high-level manpower and technical expertise for Nigeria’s petroleum and energy industries, is expected to continue its academic and research activities without disruption despite the name change.
According to the PTDF, the university will maintain its focus on delivering advanced education, research and technology-driven solutions for the country’s oil, gas and emerging renewable energy sectors.
“The institution remains firmly committed to its mandate of delivering world-class research, specialised training, and cutting-edge engineering technology solutions to power Nigeria’s oil, gas, and renewable energy sectors,” the statement added.
The Fund further assured students, academic partners, industry stakeholders and development institutions that all existing programmes, collaborations and operational activities would continue seamlessly under the university’s new identity.
“All ongoing academic programs, partnerships, and operations continue uninterrupted under this new institutional identity,” PTDF said.
The renaming comes as Nigeria intensifies efforts to build local capacity and technical expertise to support energy transition goals, deepen indigenous participation in the petroleum industry and strengthen research-driven innovation across the energy value chain.

By Modupe Gbadeyanka
A sustainability-focused programme known as Airtel Green Schools has been launched by Airtel Africa Foundation, as part of activities to commemorate the 2026 World Environment Day, themed Climate Action.
The initiative will create environmental learning spaces in primary and secondary schools, with the spaces to be branded Airtel Garden.
Already, the company’s 10 adopted schools, located in nine states across the country’s six geopolitical zones, have been onboarded as Green Schools.
Each of the schools now features an Airtel Garden, with dedicated sections for edible crops, fruit trees and shade trees, enabling pupils to learn firsthand about food cultivation, biodiversity and the importance of increasing green cover to help mitigate the effects of climate change.
The gardens also incorporate composting stations where organic waste generated within the school environment can be converted into nutrient-rich compost. To boost circular economy practices, plastic recycling segments have also been built into repurpose common wastes such as plastic bottles and tyres.
The beneficiary schools of the programme include St. George’s Nursery and Primary School, Ipaja, Lagos; Yahaya Primary School, Zaria; Iyeru-Okin Primary School, Iyeru-Okin, Kwara; St. John Primary School, Ijebu Igbo, Ogun State, and Community Primary School, Amumara, Imo State.
Others are Presbyterian Primary School, Ediba, Cross-River; Migrant Farmers Community Primary School, Umuahia, Abia State; Gwange III Primary School, Maiduguri, Borno State; Mayflower Secondary School, Ikenne, Ogun State; and Government Day Primary School, Gombe State.
“We are excited to inaugurate Airtel Green Schools, which are designed to go beyond awareness and create real behavioural change within Nigeria’s school communities.
“Through the Restore, Reduce and Educate pillars, we are equipping young people with practical tools such as gardens, recycling awareness, and environmental learning resources.
“Our goal is to create a replicable Green School model that can be scaled and sustained over time, ensuring that environmental education becomes part of everyday learning for the children in our adopted schools,” the chairman of the foundation, Mr Segun Ogunsanya, stated.
Also speaking, the chief executive of Airtel Nigeria, Mr Dinesh Balsingh, said, “Climate action becomes meaningful when awareness is translated into action. Through the Airtel Garden, we are creating living classrooms where pupils can learn practical lessons about environmental stewardship, sustainable agriculture, waste management and the importance of protecting our planet.
“We believe that empowering young people with these experiences today will help shape a more environmentally responsible generation tomorrow.”
