Question

An electric motor 5 takes 5A from a 220V line. Determine the power of the motor and
the energy consumed in 2h
A) P= 1100watt, E= 396 X 10*3KU
B) P = 1100watt, E= 3.96 x 10*4KU
C) P = 1100watt, E = 3.96 x 10*3KJ
D) P = 1100watt, E = 3.96 x 10*6KJ​

Answer 1

Answer:

Hello mate ❣❣

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 × 106J
