Explanation:
energy consumed = power * time duration
Power = energy consumed / time duration of consumption
= 500 Joules / 20 seconds
= 25 Watts or Joules/sec
Lamp has a constant power rating.
energy consumed in 15 days
= 25 watts * (2 * 3600 sec) / day * 15 days
= 2,700 kilo Joules
or,
= 25 watts * 2 hours /day * 15 days = 750 watt hours
= 0.750 kWH kilo watt hours
