The energy will be 0.33 KWh
Explanation:
Power = p = 2KW
Time = t = 10 minutes = 1/6 hour
Power is defined as the time rate of change of energy. So,
P = W/t
W = pt
W = (2KW)(1/6h)
W = 0.33 KWh
This energy will be used for boiling water in a 2KW kettle for 10 minutes

power =2 kw
2 × 1000
= 2000
time = 10 minutes
6 / 10= 1/10
energy = power × time
= 2000 × 1/6 = 1000/3
= 33.33 watt hour ans
