What is the unit of electrical pressure?

Explanation:
Voltage represents electrical pressure, the push that moves charges through a circuit. The unit for this pushing force is the volt. One volt equals one joule of energy per coulomb of charge, which captures how much energy each unit of charge has as it moves. In circuit terms, voltage is the potential difference that drives current; by Ohm’s law, current equals voltage divided by resistance. The other units measure different things: ampere is current (flow rate of charge), watt is power (voltage times current), and hertz is frequency (cycles per second). For example, a 9-volt source across a 9-ohm resistor yields about 1 amp of current, illustrating how voltage pushes current through resistance.
