What do you call the amount of work that electrical flow can do, expressed in watts or kilowatts?

The amount of work that electrical flow can do is referred to as power, which is expressed in watts (W) or kilowatts (kW). Power quantifies the rate at which electrical energy is converted to a different form, such as light or heat, or used to do mechanical work.

In physics and electrical engineering, power is calculated using the formula P = IV, where P represents power, I denotes current in amperes, and V signifies voltage in volts. This relationship shows that power is directly related to both the current flowing through a circuit and the voltage across the circuit.

Understanding power is crucial in various applications, such as determining the capacity of electrical devices, assessing energy consumption, and designing electrical systems that meet specific energy requirements.

This differentiation is crucial to avoid confusion with other terms: current refers to the flow of electricity, resistance measures the opposition to that flow, and voltage represents the potential difference that drives the current.
