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
