An electrical contractor in Austin, TX, posted a super-informative blog post about understanding AC and DC electrical currents. This is what the differences boil down to: "DC" means "direct current".

AC and DC current are to EVs what petrol and diesel are to traditional combustion-powered cars. You can think of them as ‘fuels’ to fill up your electric car’s battery. Unlike when choosing the ...

The battery as we know it today was an invention of Italian chemist and physicist Alessandro Volta. He witnessed electricity splitting water into its constituent elements of oxygen and hydrogen and ...

Making a dc voltage from an ac source means you will have to rectify the ac voltage to get a dc bus. One difference compared to a dc-dc converter is that you can use a linear power supply with an ac ...

It's essential to understand how power and energy calculations relate, especially with the increased importance of energy efficiency. Calculations of power and energy are relatively straightforward ...

Batteries aren't one-size-fits-all, and neither is the way they're wired to your house. Here's what you should know about AC- and DC-coupling. When we think about solar panels and batteries, we don't ...

Explaining how current is created and the difference between AC and DC ...

Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important for ...
