Question

3. An electric motor takes 5 amperes current from a 220 volt supply line. Calculate the power of the motor and electrical energy consumed by it in 2​

Answer 1

Answer:

I = 5 amp

V = 220 volt

T = 2 h

P = ? , E = ?

we know that,

P = V×I

= 20 × 5

= 1100 watt

= 1.1 k W

Energy consumed , E = P × t

= 1.1 ×2

= 2.2 K W H
