At what frequency will a 0.5 H inductor have a reactance of 1,000 ohm?

An alternating em.f is applied to a pure indutance such that inductive reactance is 10 ohm. If the frequency of a.c. Is doubled, the reactance will become

An ideal inductor of 1 H is connected across a resistance of 100 ohm as shown in the figure. What is the current through the inductor as soon as key K is closed?

An alternating e.m.f. is applied to a pure capacitance such that the capacitive reactance is 10 ohm. If the frequency of a.c. is doubled,the reactance will become

A coil has an inductive reactance of 160 ohm at frequency of 50 hz. Calculate the self inductance of the coil.

An ideal inductor of 1 H is connected across a resistance of 100 ohm as shown in the figure. What is the potential difference across the 100 ohm resistance, when the current has attained a steady value?

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

A coil of inductance 0.50 H and resistance 100 ohm is connected to a high frequency supply (240 V, 10 kHz). (a) Obtain the maximum current in the coil. (b) what is the time lag between voltage maximum and the current maximum. Hence, explain the statement that at very high frequency, an inductor in a circuit nearly amounts to an open circuit. How does an inductor behave in a dc circuit after the steady state?
