An electric heater of 1000 watt is used everyday for 70 mins. Calculate the units of electric energy this heater will consume in 30 days of use.

Open in App

Solution

Total energy consumed = Electric power x time
As P = 1000 watt and time,t = 70 min per day.
So energy consumed in one day = 1000 Ã— 70 Ã— 60 Joules
Now Total energy consumed in 30 days = 1000 Ã— 70 Ã— 60 Ã— 30 Joules
