Power: The rate at which work is done or energy is transferred.
Explanation
Power is calculated as work divided by time (P = W/t) and is measured in watts. Greater power means work is done faster. A 100-watt bulb consumes energy faster than a 60-watt bulb. Power rating indicates how much energy a device uses per second. Higher power consumption results in higher electricity bills.
Example
A motor rated at 1000 watts does the same work as a 500-watt motor but completes it in half the time.
