The inductance of a coil is 0.25 H. Calculate its inductive reactance in a.c. frequency 50 Hz.

A coil has an inductance of 0.5H. Calculate:- its inductive reactance when connected to 240 V (peak), 50 Hz A.C.

The inductive reactance of a coil is 1000Omega . If its inductance and the frequency of A.C. supply are both doubled, then the reactance will become

The inductive reactance of a coil is 1000 Omega . If its self inductance and frequency both are increased two times then inductive reactance will be –

An alternating voltage of 240V, 50 Hz is applied to 20H inductance coil and resistance 300 Omega . Calculate, inductive reactance power factor and power absorbed.

The frequency of a.c. is doubled, what happens to inductive reactance?

The inductance of a coil is 10 H. What is the ratio of its reactance when it is connected first to an A.C. source and then to a D.C. source?
