Fundamentals of DC and AC circuits

Understand the Problem

The question is inquiring about the basic principles and concepts related to DC (Direct Current) and AC (Alternating Current) circuits. This encompasses the understanding of how these circuits operate, their differences, and key components involved.

Answer

In DC, electricity flows in one constant direction; in AC, the direction periodically reverses.

The final answer is that in direct current (DC), the electricity flows in one constant direction, whereas in alternating current (AC), the direction of the electricity flow periodically reverses.

Answer for screen readers

The final answer is that in direct current (DC), the electricity flows in one constant direction, whereas in alternating current (AC), the direction of the electricity flow periodically reverses.

More Information

An interesting fact is that AC is commonly used for power supply in homes and businesses because it is more efficient over long distances, whereas DC is typically used in battery-powered devices and electronics.
