What is the behavior of the capacitor in an AC circuit?

Once the capacitor is “fully-charged” the capacitor blocks the flow of any more electrons onto its plates as they have become saturated. However, if we apply an alternating current or AC supply, the capacitor will alternately charge and discharge at a rate determined by the frequency of the supply.

How does inductor behave in AC current?

Inductive Reactance against Frequency Well the self induced emf in the inductor is determined by Faraday’s Law that produces the effect of “self-induction”. When a current passes through an inductive coil, the rate of change of the AC current induces an emf in the same coil that counteracts the changing current.

How does a capacitor and inductor behave while switching?

An inductor opposes change in current and a capacitor opposes change in voltage. When an inductor is connected, the voltage across it will be equal to the terminal voltage, whereas, the current through it will take time to change.

What is the Behaviour of inductor and capacitor for current and voltage in steady state condition?

Capacitors become open circuits, which means that there is a break in the circuit, in D.C. steady state, while inductors become short circuits, which means they become a wire, in D.C. steady state. A good way to remember this is to understand why this occurs. Capacitors store charge in a electrostatic field.

Do inductors act like resistors?

Inductors store energy in the magnetic field created by the passage of a current. thus, if you have a voltage / an alternating current, the inductor resists this and the more the frequency is high, the more the current tries to change quickly, and thus more the inductor resists. they do not behave like resistors.

How does a capacitor behave?

Because capacitors store energy in the form of an electric field, they tend to act like small secondary-cell batteries, being able to store and release electrical energy. Once the capacitor has reached the full voltage of the source, it will stop drawing current from it, and behave essentially as an open-circuit.

What is the response of a capacitor and an inductor to a AC voltage?

Inductor and capacitor are two electrical elements which helps to store the electrical energy. Inductor does not allow sudden change in the current passing through it. It dissipates energy stored in it to avoid sudden change. Similarly capacitor does not allow sudden change in the voltage applied across it.

How does capacitor and inductor behave in steady state?

The capacitor behaves as open circuit and inductor behaves as closed circuit in steady state condition.

Why AC is blocked by inductor?

Since inductor behaves like a resistor, DC flows through an inductor. The AC flowing through L produces timevarying magnetic field which in turn induces self- induced emf (back emf). This back emf, according to Lenz’s law, opposes any change in the current. Therefore L blocks AC.
