Given,

I = 5 A
V = 220 V
t = 2 hr = 7200 s
P = ?

We know

Power (P) = Voltage (V) x Current (I)

Substituting the values, we get

P = 220 × 5 = 1100 W

The energy consumed by the motor (E) = P × T

Substituting the values, we get

E = 1100 × 7200

= 79,20,000 J

= 7.92 × 10⁶ J

Hence, power of the motor is 1100 W and the energy consumed is 7.92 × 10⁶ J.
