Question

An iron cored coil connected to a 100V,50Hz supply is found to take a current of 5A and to dissipate a power of 200W.Calculate the resistance,inductane and power factor​

Answer 1

Answer:

Given,

f=50Hz

V0=200V

I=2A

P=100W

In an A.C, the capacitor does not consume any power,

So, the power consumed in the circuit is,

P=I2R

R=I2P=22100

R=25Ω
