● P = VI V = 220V, and I = 5A.
●Power P = 220 × 5 = 1100 W
●Power of the motor = P × t P = 1100 W.
●t = 2 Hr 2 × 60 × 60 W = 7200 S
●∴ Energy consumed, E = 1100 × 7200 J = 7920000 = 7.92 × 106J

Answer:
Step 1: Given data
Supplied voltage, V=220volt.
The current through the motor is, I=5A.
the time of consumption is, t=2h. or 2×60×60seconds= 7200seconds
Step 2: Calculation of power
As we know, power is P=VI.
So,
P=220×5=1100
orP=1100watt.
Therefore, the power of the motor is 1100watt.
Step 3: Calculation of energy consumption
We know that energy consumed by a body is E=P×t.
So,
E=1100×7200
orE=7920000joule.
orE=7.9×106joule.
Therefore, the energy consumed in 2 h by the motor is 7.9×106joule.
