Question

Direct current is the flow of an electric charge _____.

A. that regularly reverses direction

B. that regularly stops and starts again

C. that moves in only one direction

D. that stops at a specific point

Answer 1

Answer: Direct current = that moves in only one direction

Explanation :

Electric current is defined as the electric charge per unit time. The electric current is of two types

• Direct current
• Alternating current

In direct current, the current flows one in one direction while in alternating current the current changes its direction periodically. So, the correct statement that describes the direct current is " (C) that moves in only one direction ".

Answer 2

For the answer to the question above, 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. So my answer is A.
