Question

a bulb of 100 w is used daily for 4 hrs , a fan of 60 w is used daily for 10 hrs, an ac of 1.5 kw for 2hrs , and a tubelight of 40 w daily for 8 hrs calculate the total monthly energy consumption and the cost of electricity consumed if rate of electricity is Rs 10 per unit ​

Answer 1

Answer:

Energy = Power*time

Energy consumed by 100 W bulb per day = 2∗100 Wh                

                                                                     = 0.2 kWh

Energy consumed by 40 W bulbs per day = 4∗40∗4 Wh

                                                                     = 0.64 kWh

Total energy consumed per day = 0.2 + 0.64 kWh

                                                  = 0.84 kWh  

Therefore, the energy consumed in 30 days = 30∗0.84 kWh

                                                                                   = 25.2 kWh
