Question

An electric motor takes 10 A current from 220 V supply line. Determine the power of the motor and energy consumed in 4 hr​

Answer 1

Answer:

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 7200ot time mei 2 ki jagah 4 hoga

P = 7.92 x 106 J

Therefore, power of the motor = 1100 W

Energy consumed by the motor = 7.92 x 106 J

replace krke calculate krlena

5 ki jagah 10 hoga

Answer 2

Answer:

Given parameters

Voltage (V) = 220 V

Current (I) = 10 A

Time (t) = 4 h = 4 x 60 x 60 = 14400 s

Power (P) is given by the expression,

P = V × I

P= 220 x 10

P = 2200 W

Energy consumed by the motor = P x t

P = 2200  ⨉  14400

P = 31680000 j or 31.68  ⨉ 10⁶ j

Therefore, power of the motor = 2200 W

Energy consumed by the motor = 31.68  ⨉ 10⁶ j
