### 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.

**Answers:-**

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 × 10^{6}* *J
