Explanation:
An electric motor takes 5 A from a 220 V line. Determine the power of the motor and the energy consumed in 2 h.
Answer:
Given parameters
Voltage (V) = 220 V
Current (I) = 5 A
Time (t) = 2 h = 2 x 60 x 60 = 7200 s
Power (P) is given by the expression,
P = V × I
P= 220 x 5
P = 1100 W
Energy consumed by the motor = P x t
P = 1100 x 7200
P = 7.92 x 106 J
Therefore, power of the motor = 1100 W
Energy consumed by the motor = 7.92 x 106 J
