Question 2:
An
electric motor takes 5 A from a 220 V line. Determine the power of the motor
and the energy consumed in 2 h.
Solution:
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
P=VI
=220×5watts
=1100w
Now Energy
consumed by the motor
H= Pt
=1100×7200J
=7.92 × 106 J
