Question

the electric motor is rated 1.5kW- 250V. calculate the current flowing into the motor ,the energy consumed by it in one second, the time in which it will consume 90kWh of energy ​

Answer 1

Answer:Power=1.5kw

Voltage=220v(general voltage in domestic circuit)

Power=voltage ×current

1.5×1000watts=220×current

1500=220×current

Current=1500÷220

Current drawn=6.81amps(approx)

But it is operated on 5A circuit

So it leads to overloading and thus short circuit
