An electric motor takes 5A from a 220V line. Determine the power of the motor and the energy consumed in 2h. |
|
Answer» Solution :It is given that CURRENT drawn by ELECTRIC MOTOR `I=5A` the line voltage `V=220V` and TIME t=2h `therefore`Power of the motor `P=VI=220V times 5A=1100W` and the energy consumed `E=Pt=1100W times 2h=2200W h or 2.2kWh` |
