Question

How much electric energy is consumed by a 100W lamp used for 6 hrs everyday for 30 days..?

Answer 1

energy consumed = power *time

E=100*6*30

E=100*180

E=18000Wh

E=18kWh

E=3.6*18*10^6J

E=6.48*10^6J

Answer 2

Answer : 18kWh

explanation :

Power = 100W

Usage = 6 hrs/day

Total number of days of usage = 30 days

Total Energy Consumed = Power × Total Usage

=> 100 × 6 × 30

=> 18,000 Wh = 18kWh
