a current of 1.1 A flows through a coil when connected to a 110 V DC source . when 110V -50 Hz AC is applied to the same coil , only 0.5 A current flows . calculate the resistance ,impedance & inductance of the coil.

Answer 1

What is your question about this? It is exceedly straightforward
resistance= dcvoltage/dccurent
impedance=acvoltage/ac current
from those two, you can calulate the inductive reactance (it is a right triangle)
then the inductance is wL=reactance
