Answer:
1100W, 7,920,000J
Explanation:
Power is equal to potential difference x current = 220×5 = 1100W
energy consumed = power × time = 1100W × 2×60×60 sec= 7,920,000J

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
