Question

an electric motor takes 5 a from a 220 V line determine the power of the motor and energy consumed in 2 hours​

Answer 1

Answer:

Step-by-step explanation:

p=vi

p=5*220

p=1100 watt

e=power*time

e=1100*2

e=2200J

Answer 2

Step-by-step explanation:

Given that,

An Electric Motor takes 5A from a 220V line.

Since,

Power(P) = I x V

               = 5 x 220 W

               =  1100 W

               = 1.1 kW  [∵1000 W = 1 kW]

∴Power of the motor is 1.1 kW or 1100 W

Since,

Energy = Power x time

Energy = 1.1 x 2 kWh

            = 2.2 kWh

Therefore energy consumed in 2 hr. is 2.2 kWh
