Question

a electric motor takes 5 ampere from a 220 volts line. determine the power of the motor and the energy consumed in 2 hour

Answer 1

Answer:

Explanation:

Given :-

Current in the motor = 5 ampere          

Potential difference = 220 V          

Time = 2 hours

To Find :-

The power of the motor and the energy consumed.

Formula to be sued :-

Power of the motor = V × I    

Energy = power × time  

Solution :-

Putting all the values, we get      

Power of the motor = V × I          

Power of the motor = 220 × 5          

Power of the motor = 1100 watt or 1.1 kW  

Hence, the power of the motor is 1100 watt or 1.1 kW.  

Now, Energy = power × time          

Energy = 1.1 kWh × 2 h.          

Energy = 2.2 kWh

Hence, the energy consumed in 2 hour is 2.2 kWh.

Answer 2

Answer:

The power of the motor and the energy consumed. hence, the power of the motor is 1100watt or 1.1 kw energy =1.1 kwh x 2h . hence, the energy consumed in 2 hour is 2.2kwh
