DC Current

Definition

DC (Direct Current) is the flow of electric charge that only moves in one direction. It has a constant magnitude and does not change with time.

AC Current: AC (Alternating Current) is the flow of electric charge that periodically changes direction. It oscillates back and forth, like waves on the ocean.

Voltage: Voltage is the electrical potential difference between two points, which causes charges to move within a circuit.

Resistance:

Resistance is an electrical property that opposes the flow of current. It determines how much current will flow for a given voltage.
