The electrical energy can be determined using the relationship between electric power and time. The formula for electric power is:
Power = Energy / time
Rearranging this formula, we get:
Energy = Power x time
So, to determine the electrical energy used over a given time period, we simply need to multiply the electric power by the time for which it is used.
For example, if a device has an electric power of 100 watts and is used for 2 hours, the electrical energy used can be calculated as:
Energy = Power x time
= 100 watts x 2 hours
= 200 watt-hours (Wh)
This means that the device used 200 watt-hours of electrical energy over the 2-hour period.
