One watt is a unit of energy that equates to one joule per second. Put simply, power can be defined as the energy usage rate at which work is done or energy gets used – you could even refer it to having “the ability to do work”, whether this involves creating electricity or using...
the end. This energy could be supplied by a battery (in a circuit) or by a person riding a stationary bike (in the yard). The amount of energy needed to keep the molasses flowing at a rate of one coulomb per second is a joule. The production of one joule per second is one watt....
