Calculating Energy Used by a Motor

How to calculate energy used by a motor?

Calculate the energy used by a 2.0 hp motor that runs for 1.0 hour. (1 hp - 746 W)

Answer:

The 2.0 hp motor uses 1492 joules of energy when it runs for 1.0 hour.

To calculate the energy used by the motor, we first need to convert the power of the motor from horsepower (hp) to watts (W). One horsepower is equal to 746 watts. In this case, the motor has a power of 2.0 hp, so when converted to watts, it will be 1492 watts (2.0 hp x 746 watts/hp = 1492 watts).

Next, we multiply the power (1492 watts) by the time the motor runs, which is 1.0 hour. By multiplying the power by the time, we get the total energy used by the motor, which is 1492 joules of energy (1492 watts x 1.0 hour = 1492 joules).

Therefore, the 2.0 hp motor uses 1492 joules of energy when it runs for 1.0 hour.
