(a)Electric Power is defined as the rate at which electrical energy is consumed by an electric appliance.
(b)Given Power of the heater is 2kW....and t = 2 hour per day for 30 days(i.e a month) which is 2×30=60 hours.
So Power consumed by the heater in 30 days=2kW×(2×30)h=2×60kWh=120kWh
(c)Since Cost of one unit of power (or 1kWh) is Rs 4...so the cost of 120kWh will be=Rs(120×4)=Rs 480.

hey mate here is your answer ❤️❤️❤️❤️❤️❤️

Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second.

heater is used for 2 hours and it's power is 2 kWh

then 2×2kwh=4kwh per day.
then in one month

4×30=

120 units of energy is consumed...
cost
120×4
480 is cost...
this may help you.....

hrishikeshfbr: ha

hrishikeshfbr: you wrote 360

hrishikeshfbr: And you have a different definition

hrishikeshfbr: followed
