Question

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

Answer 1

Hi !

Current = I = 5 A
Voltage = V = 220 V
Power = P = ?
Time = T = 2 hr
Energy = E = ?

P = I × V
   = 5 × 220
   = 1100 W

E = P × T
   = 1100 W × 2 hr
   = 2200 W hr
   = 2200/1000 kWh
  = 2.2 kWh

( ∵ 1 kWh = 1000 W)
