Answer:The power of the motor and the energy consumed. Hence, the power of the motor is 1100 watt or 1.1 kW. Energy = 1.1 kWh × 2 h. Hence, the energy consumed in 2 hour is 2.2 kWh.
Explanation:
Power (P) is given by the expression,
P = VI
Where,
Voltage,V = 220 V
Current, I = 5 A
P= 220 x 5 = 1100 W
Energy consumed by the motor = Pt
Where,
Time, t = 2 h = 2 x 60 x 60 = 7200 s
ˆ´ P = 1100 x 7200 = 7.92 x 106 J
Therefore, power of the motor = 1100 W
Energy consumed by the motor = 7.92 x 106 J
