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. Most of the digital electronics that you build will use DC.
Voltage is the cause and current is its effect. Voltage is the potential difference between two points. When charges flow due to this potential difference, we say that currentâ¦ is flowing. Voltage and current can be compared to a water reservoir with tubes connected to the outlet, the reservoir is the supply.
