What term refers to the rate at which energy is transferred or converted?

The rate at which energy is transferred or converted is known as power. Power quantifies how quickly work is done or energy is transferred in a system. It is measured in watts (W), where one watt is defined as one joule per second. This concept is essential in various fields of engineering, as it helps in understanding how efficiently a device operates or how much energy is being consumed or produced over time.

When considering other terms like voltage, force, and work, they refer to different physical concepts. Voltage relates to the electrical potential difference and is a measure of the force driving electric current through a circuit. Force is a vector quantity that causes an object to accelerate and is not specifically related to energy transfer over time. Work, on the other hand, is defined as the amount of energy transferred by a force through a distance, but it does not directly measure the rate of energy transfer. Thus, power is the correct term that represents the rate of energy conversion or transfer.
