What happens when a DC voltage is applied to an inductor?

When DC is used in an inductor there will be no change in magnetic flux since DC does not have zero frequency. Therefore, the inductor acts as a short circuit in DC.

What happens when you apply current through an inductor?

An inductor typically consists of an insulated wire wound into a coil. When the current flowing through the coil changes, the time-varying magnetic field induces an electromotive force (e.m.f.) (voltage) in the conductor, described by Faraday’s law of induction.

What is the relationship between the current through the inductor and the behavior of an inductor in a DC circuit?

Energy stored by an Inductor If the current flowing through the inductor is constant as in a DC circuit, then there is no change in the stored energy as P = Li(di/dt) = 0. So inductors can be defined as passive components as they can both stored and deliver energy to the circuit, but they cannot generate energy.

What happens to the current in an inductor when a capacitor?

When the switch is closed at t=0 capacitor behaves as a short circuit while the inductor behaves as an open circuit as the voltage across the inductor immediately jumps to battery voltage. Now we know that the current in inductor increases while in a capacitor current decreases with respect to time.

What is the function of inductor in DC Circuit?

Upon initial application of the DC source, the inductor acts as a choke, limiting the current flow. As time passes, the impedance of the inductor will reduce to zero and the current will stabilize at whatever the total circuit impedance is.

Why is the voltage inside an inductor zero?

Although there is no current flowing through the inductor there is still an instantaneous rate of change of current which produces a voltage across the inductor equal to the voltage of the cell E and so the total voltage in the circuit is still zero. The inductor has no magnetic field associated with it and so is storing no energy.

How does DC affect the magnetic flux of an inductor?

Once the steady state has been reached, DC will have no effect on an inductor. It acts as if the inductor and a straight conductor are the same. But till it reaches steady state, the current is increasing. So, magnetic flux increases with increase in current.
