Question

answer the question ​

Answer 1

Answer:

Explanation:

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

Answer 2
