Voltage:

Voltage, also known as electric potential difference, is the force that pushes electric charges through a circuit. It is measured in volts (V).

Current:

Current refers to the flow of electric charge in a circuit. It is measured in amperes (A).

Resistance:

Resistance is an opposition to the flow of electric current. It determines how much current will flow for a given voltage. It is measured in ohms (Ω).
