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.

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".

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 ...

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?

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.

AC or DC: Which Is Better? Your gadgets run on direct current, but the electricity in your home is alternating current. What’s up with that?

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.

Linear ac-dc power still has a place in lab supplies and high-end audio, but most modern power conversion uses switching voltage regulators, not linear ones.

Chapter 7: Alternating Current Question 1: Derive the expression for the impedance in an LCR series circuit. Question 2: Explain the concept of resonance in an LCR circuit.

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.
