Question

Comparison of Alternating Current and Direct Current

Answer 1

In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction.

Because AC is easy and cheap to transform from one voltage to another using transformers. High voltage means less amperage for the same power, meaning you can do with thinner wires. So high voltage DC transmission lines are now becoming more popular. DC has the advantage that you have no losses due to EM radiation.

Hope this helps!!

Answer 2

alternating current AC is used for long distance travel of current and use in our houses but the direct current DC is used for short distance travel of current like in battery or cell.
