Question
How much electric energy in kWh is consumed by an electrical appliance of 1000 watts when it is switched on for 60 minutes?
Solution
Power,
(P) = 1000 W
= 1 kW
Time duration,
(t) = 1 hr
Now, we can calculate the electrical energy consumed as,
Energy consumed = (Power) (Time)
So,
Energy consumed
= (1)(1) kWh
= 1 kWh
So, energy consumed is 1kWh.
