The joule is the unit of which quantity?

Explanation:
The joule measures energy (and the amount of work transferred). It quantifies how much energy is used or transferred when a force moves something a certain distance: 1 joule equals a force of 1 newton acting over 1 meter. In electrical terms, energy delivered by a device is counted in joules, while the basic electrical quantities have different units—current in amperes, voltage in volts, and resistance in ohms. A handy way to connect things is that power is energy per time, with 1 watt equaling 1 joule per second. For example, using a 60-watt device for 1 second transfers 60 joules of energy.
