When it comes to charging electric vehicles (EVs), two primary methods are commonly used: Alternating Current (AC) and Direct Current (DC) charging. Both serve the same purpose—recharging the EV ...

We explain the difference between AC and DC electricity. How do these types of current affect how long it takes to recharge an electric car?

Batteries are a part of our everyday life, and power everything from phones to gaming handhelds to laptops, but do those batteries use AC or DC current?

AC and DC power differ in direction, usage, and efficiency. Learn the basics of how alternating and direct current work and where each is used.

Power relays are specifically designed to handle either AC or DC. It’s important to know the fundamental differences between them before building them into a system.

Rectifying ac has other problems, such as the surge current that it will draw (Fig. 1). This is different than inrush current, which dc-dc supplies also have, when you first apply power to them.

Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the difference between basic types of motors in the past.

While that’s an easy and understandable assumption, it can also be a dangerous one, as this demo of AC and DC switching dramatically reveals.
