Answer:
The answer to this question is = 2.2 KWh
Explanation:
The work done in moving 5 A charge through Potential difference 220 V is
= W = V*I
W = 220*5
W = 1100 W = 1.1 KW
The energy consumed in 2 hours
= 1.1 KW * 2 h = 2.2 KWh

Answer:
Electric current = 5 A
potential different = 220 V
Time = 2 x 60 x 60 = 7200
P = VI
220 x 5 V
=> 1100 w
Energy consumed by motor,
=> 1100 x 7200
=> 7.92 x 10^6 J
