What is the measurement of how much electricity is being used in one second called?

The measurement that indicates how much electricity is used in one second is referred to as a Watt. A Watt is defined as the rate of energy transfer equivalent to one joule per second. Therefore, when we talk about power consumption, we are essentially discussing how many watts of electricity are used within a specified time frame.

Volts measure electrical potential, which is essentially the pressure of electricity, while Amps measure the flow of electric current, akin to the volume of water flowing through a pipe. Joules represent a unit of energy, indicating the total amount consumed over time but do not convey the rate of use directly. Therefore, Watts are the correct answer as they combine both voltage and current to give a clear picture of electricity being utilized at a given moment.
