if it takes 15 minutes to dry your hair with a 1.200 kW Hair dryer, how much energy is used in drying your hair?

1 answer

To calculate the energy used in drying your hair, we need to first convert the time from minutes to hours:

15 minutes = 15/60 hours = 0.25 hours

Next, we can use the formula:

Energy = Power x Time

Energy = 1.200 kW x 0.25 hours = 0.3 kWh

Therefore, 0.3 kilowatt-hours (kWh) of energy is used in drying your hair.
