What does DC stand for in the described voltage description?

• A. Direct current
• B. Dynamic current
• C. Direct charge
• D. Duty cycle

Answer: (A)

DC stands for Direct current. This means the current flows in one direction and the voltage maintains a constant polarity over time, unlike alternating current where the direction and magnitude change periodically. Direct current is produced by batteries and DC power supplies and is used for most small electronics. The other terms aren’t standard ways to describe current types: dynamic current isn’t a common designation, direct charge isn’t the correct terminology, and duty cycle refers to the proportion of time a signal is on in a pulsed waveform, not the basic type of current.
