Question

If there any difference between 1 kW and 1 kWh? Explain.

Answer 1

1. 1 Kilowatt $\left(kW\right)$ is the measure of power that an electrical appliance consumes. $(1kW=1000W)$.
2. 1 Kilowatt-hour $\left(kWh\right)$ is the energy consumed when using a power of $1kW$ for $1h$. In other words,$1kWh$ equals one hour of electricity usage at a rate of $1kW$.

Therefore, 1 kW is a measure of power while 1 kWh is a measure of electrical energy.
