What is an AC circuit?
Understand the Problem
The question seems to be asking for information about AC circuits, likely seeking an explanation or definition of what they are or how they function.
Answer
An AC circuit features periodically changing sinusoidal current and voltage.
An AC circuit is powered by alternating current (AC), which means the current and voltage change periodically in direction and magnitude, typically following a sinusoidal wave pattern.
Answer for screen readers
An AC circuit is powered by alternating current (AC), which means the current and voltage change periodically in direction and magnitude, typically following a sinusoidal wave pattern.
More Information
AC circuits can utilize components such as resistors, capacitors, and inductors, and are commonly used to supply power to homes and businesses because AC can be easily transformed to different voltages.
Tips
A common mistake is confusing AC with DC (direct current), which maintains a constant voltage or current.
