Which unit is used to measure electrical power?

The unit used to measure electrical power is the watt. Power in electrical systems is defined as the rate at which electrical energy is converted into another form of energy or used in a circuit.

One watt is equivalent to one joule per second, which means it measures how much energy is used or produced in a specific time frame. This relationship highlights the connection between power and energy over time, allowing for the quantification of how effectively an electrical device performs its function.

In practical applications, the watt is commonly used to rate the power of electrical devices, such as light bulbs, appliances, and motors. This helps consumers understand how much energy a device will consume when in use, informing decisions about energy efficiency and costs.
