what is Voltage Quiz Practice Quiz | what is Voltage

Electrical potential difference — Voltage represents the potential energy difference between two points.

Volt (V) — Voltage is measured in Volts, named after Alessandro Volta.

Electromotive force (EMF) — EMF, or Electromotive Force, drives the flow of current in a circuit, which is voltage.

Power source (e.g., battery) — The power source provides the electrical potential difference.

V = I * R — Ohms law states: Voltage (V) equals Current (I) multiplied by Resistance (R).
