electric power is the electrical energy consumed by an appliance in unit time or it is the rate of transfer of energy in electrical circuit. it is represented as p = e/t where p = power e = energy t = time
power or the wattage of the motor = 2kW
time for which it is used in one day = 2 hrs
energy used in one day = p*t (p=e/t) = 2*2= 4 units
days in sept. = 30
energy used in 30 days = 4*30 = 120 units
cost of one unit = rs 6
cost of 120 units = 120*6 = 720 rs
power or the wattage of the motor = 2kW
time for which it is used in one day = 2 hrs
energy used in one day = p*t (p=e/t) = 2*2= 4 units
