What happens when AC passes through inductor?
When alternating current flows through the inductor, it produces a magnetic field around it, which by turn produces flux. The alternating flux produces an emf whose direction is opposite to the very cause of it ( Lenz’s law).
How does a inductor react to AC?
Inductor works similarly to capacitor, but here we need to check for sudden change in current. So, for a DC source, Current is constant, So Inductor act as short circuit element and for a AC source, Inductor act as a resistor. Here Reactance of a Inductor is equal to 1/(2*pi*frequency*Inductance).
How does inductor block AC current?
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.
How are inductors different for the cases of AC and DC current How are inductors similar and different to capacitors?
What is this? Capacitors store energy in an electric field. Inductors store energy in a magnetic field. In a capacitor, energy is calculated in terms of voltage….Table of Differences between Capacitors and Inductors.
| Feature | Capacitor | Inductor |
|---|---|---|
| DC Current | Current Decreases Over Time | Current Increases Over Time |
When an electric current flow through the inductor in a circuit energy will be stored in the form of?
magnetic field
An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it.
Why inductor allows DC to flow but blocks AC?
An inductor blocks AC while allowing DC because it resists a change in current. If you apply DC across an inductor, it will stabilize to some current flow based on the maximum current available from the current / voltage source.
How are inductors different for the cases of AC and DC current?
In other words, the inductor is a component that allows DC, but not AC, to flow through it. The inductor stores electrical energy in the form of magnetic energy. The inductor does not allow AC to flow through it, but does allow DC to flow through it.
Does an inductor increase current?
As an inductor stores more energy, its current level increases, while its voltage drop decreases.
