# 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, Electric current (I) = 5A,
Potential difference (V) = 220V,

Time (t) = 2h = 2 x 60 x 60 s = 7200 s

We know,Power (P) = V I = 220 x 5

P= 1100 W

Energy consumed by the electric appliance = P × t=1100 W × 7200 s

Energy consumed= 7.92 × $$10^6$$ J
