When inductor is called short circuit and open circuit?
In DC inductor is short circuited .
What is the symbol for an inductor?
The inductor symbol resembles a coil of wire of 3 to 5 turns.
Is a inductor linear device?
Inductor is a nonlinear device. since v=L di/dt.
What is the resistance of an inductor called?
The resistance of an inductor is generally referred to as the series resistance, sometimes noted as RL. Note that resistance is a DC measurement and that an "ideal" textbook inductor has an RL of 0. The reactance of an inductor is an AC measurement which measures the reaction of a component's current flow to an alternating voltage and is frequency dependent and directly proportional to the inductor's inductance, measured in Henrie's. The impedance is most commonly used when talking about inductors or capacitors and is a combination of resistance and reactance.
If an inductor and a switch are connected in parallel through which the current will flow in an AC circuit?
A:The inductor does not allow ac signal to pass through. It blocks ac and passes dc. If the switch is open, then the ac signal wont pass. If the switch is closed, then the ac signal will pass through the switch.AnswerIt is incorrect to say that an inductor 'does not allow' the passage of an alternating current. An a.c. current will pass through an inductor, although the inductor will limit the value of that current due to the inductor's inductive reactance. Inductive reactance, which is expressed in ohms, is directly-proportional to the inductance of the inductor and to the frequency of the supply. The value of the current is determined by dividing the supply voltage by the inductive reactance of the inductor.If the switch is connected in parallel with the inductor, then closing the switch will apply a direct short circuit across the inductor, and the resulting short-circuit current will cause the circuit's protective device (fuse or circuit breaker) to operate.
What is the purpose of a inductor?
The purpose of an inductor is to store and release energy in the circuit usually in order to induce a phase shift in the voltage or current passing through it. Inductor stores energy in the magnetic field.
Why is an inductor used for?

How do you increase the inductance in a inductor?
Since we know that inductance of an inductor depends on the length of inductor by the formula L=muAN*N/l, where l is the length of inductor. So by varying the length of inductor we say that inductance of inductor varies.
What is the purpose of capacitor in the circuit?
To store energy, in an electric field between separated charges. (An inductor stores energy in a magnetic field surrounding a current.)

May I know the properties of an inductor?
Some of them are: 1. Inductor temporarily stores energy in form of magnetic field. It is given by E=½LI² here L is inductance & I is current. 2. Inductor causes current to lag voltage by 90°. 3. Inductor consumes reactive power. 4. Inductor oppose current change in circuit for AC only. Fo DC it act as simple wire. 5. Inductors are used for blocking the AC while passing the DC. They are known as chokes. 6. Inductors are used to create magnetic fields in electrical machines for the purpose of energy conversion.
Is there no induced voltage in an inductor unless the current is changing?
In an ideal inductor, no, there is no voltage induced across an inductor unless the current in the inductor is changing. However, since there are no ideal inductors nor power supplies, eventually an inductor will draw a constant current, i.e. the limit of the power supply; and, since no inductor has zero ohms at equilibrium, that current will translate to voltage.
How do you construct an inductor?
any conductor wound with few turns can be considered as an inductor
What happens when a inductor reaches a steady state?
An inductor looks like a piece of wire to DC. It will thus look like a resistor, and inductor properties do not apply.
What is working principle of inductor?
A changing current through an inductor induces a voltage into the inductor, the direction of which always opposes the change in that current.So, in a d.c. circuit, an inductor will oppose (not prevent) any rise or fall in current, although the magnitude of that current will be determined by the resistance of that inductor, not by its inductance.In an a.c. circuit, because the current is continuously changing both in magnitude and in direction, it acts to continuously oppose the current due to its inductive reactance. Inductive reactance is proportional to the inductance of the inductor and the frequency of the supply. The vector sum of the inductive reactance of the inductor and the resistance of the inductor, is termed the impedance of the inductor. Inductive reactance, resistance, and impedance are each measured in ohms.
What is meant by inductor and name the inductor device?
a coil. a component having the property of inductance.
When inductor is called short circuit and open circuit?
In DC inductor is short circuited .
