Q. An electric motor takes 5 A from a 220 V line. Determine the power of the motor and the energy consumed in 2 h.
Given that electric current (I) = 5A, Potential difference (V) =220V
Time (t) =2h=2×60×60s=7200s
Now Power (P) is given by the expression
Now Energy consumed by the motor
=7.92 × 106 J
