volt Quiz Practice Quiz | volt

Electrical potential difference — Volts quantify the 'push' that drives electrical current. This is also known as voltage or potential difference.

Watt/Ampere — Voltage (V) = Power (W) / Current (A), hence a volt is equivalent to Watt per Ampere.

12 Joules of energy per Coulomb of charge — Voltage is defined as energy per unit charge. 1 Volt = 1 Joule/Coulomb.

Increase the current — According to Ohm's Law (V = IR), increasing voltage directly increases current, assuming resistance is constant.

Voltmeter — A voltmeter is specifically designed to measure the potential difference (voltage) between two points.
