Question

A television uses 75 W while in use. Assuming that it is used 4 hours every day, how much energy in kWh would the television consume annually?​

Answer 1

Answer:

108 kWh

Explanation:

Given,

Power rating of televison (P) = 75 W = 75/1000 kW = 0.075kW

Time for which it is used per day= 4 h

in one month = 4 * 30 = 120

in one year = 120 * 12 = 240 h

energy consumed annualy = 0.075 * 240 = 108 kWh
