Why doesnt a field coil in a DC shunt motor lead to short ciruit when it is a fact that an INDUCTOR is a short circuit to DC?
Yes, an inductor is a short circuit to dc...that's true....IF the inductor is an ideal one, that is, the inductor has no resistance but has inductance only. Anything in real world, as you know, is not ideal. An inductor is usually made of a copper wire. A copper wire has its own resistance. If an inductor coil is thin and long (i.e. many turns), it will provide an appreciable resistance to DC, and will no longer be a short circuit.

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.
In which place an inductor store energy in it?
Because inductor forms a coil with magnetic field around it. It acts as a relay also. Tasleem
What is trapped energy of inductor?
An inductor resists a change in current. It does this by converting the current into a magnetic field. If the current then changes, the collapsing or increasing magnetic field will buck the attempted change through electromagnetic energy conversion.
What is the difference between an inductor and a capacitor?
Firstly the suffix '-ance' in each of those three words indicate the properties the material exhibits. Therefore resistance is the property by which any material tends to oppose the flow of current through it. Inductance is the property by which a material opposes the change in current, or opposes an alternating current. An inductor can be appreciated simply using a coil of insulated wire, or a solenoid. Capacitance is the property by which a material opposes the change in voltage across its ends, ie how it opposes alternating voltage. A capacitor comprises of, essentially, two metallic plates separated by a dielectric (a medium which may/may not be non-conducting, but is capable to contain charge). cheers!!
What is the phase angle between voltage and current in a purely capacitive circuit?
Current leads voltage (or voltage lags current) by 90° in a purely capacitive circuit. Try to remember it this way: capacitors resist change in voltage, hence the voltage lags (they resist voltage change because the voltage first goes to charging up the electric field in the capacitor).Inductors resist change in current (energy in an inductor is in the form of magnetic fields, which are caused by the current through the wire). Remember an inductor is a coil (like an electromagnet, or a transformer).
Is a circuit a path made for magnetic field?
A circuit is a path for charge particles -- it conducts current. An inductor, a circuit component, generates a magnetic field, when an AC is on. ======================
How does an inductor work to store and release energy in an electrical circuit?
An inductor works by storing energy in the form of a magnetic field when current flows through it. When the current changes, the magnetic field also changes, inducing a voltage in the inductor. This stored energy can then be released back into the circuit when needed.
How does current flows when inductor n capacitor r in series?
The stronger the magnetic field on your inductor the greater amount of current you will have flowing through your series circuit.
How does an inductor work?
An inductor works by storing energy in a magnetic field when an electric current flows through it. This magnetic field resists changes in the current, which can be used to control and regulate the flow of electricity in a circuit.
What is the purpose of a capacitor in a circuit?
To store energy, in an electric field between separated charges. (An inductor stores energy in a magnetic field surrounding a current.)
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.)

What is Inductor transient response?
An inductor resists a change in current through the creation/destruction of the magnetic field around the inductor. In an IR Circuit, when the electromotive force (the battery voltage) changes, the inductor will create a voltage to oppose the change, causing the current flowing through the circuit to change gradually over time rather than instantaneously. In an ideal IR circuit, the induced voltage is initially equal and opposite to the change in electromotive force, and it decays exponentially, with a time constant proportional to the inductance of the circuit.
How does an inductor work and what are its key functions in an electrical circuit?
An inductor works by storing energy in a magnetic field when an electric current flows through it. Its key functions in an electrical circuit include resisting changes in current flow, filtering out high-frequency signals, and storing energy that can be released when needed.
What does a inductor do in a circuit?
DC current has no effect on the inductor(can be considered as a short circuit) as the current does not change in a DC supply voltage this one just produces a magnetic field which remains constant , as the magnetic field is not varying no emf is induced in the circuit , so literally it has no effect on the circuit when the supply is of DC voltage.when an alternating current is set up in a circuit , the Alternating current brings a magnetic field in the inductor which is variable (since the current is varying...) this variable magnetic field induces an emf in the circuit (back emf) which opposes the cause that is producing the change (lenz's law)explanation consider a circuit with an inductor connected to an AC voltageduring the positive half cycle when the voltage increases the current also increases in the circuit [take the current direction as clockwise] this causes a variable increasing magnetic field in the inductor , this magnetic field in turn induces current in the circuit which is opposing the increase in the current flow from the original source, the inverse happen during the decreasing half of the half of the positive cycle , here the induced current adds up with the decreasing current opposing the cause that produced this back current (cause :- decrease in current changes the magnetic field so the induced current is produced ..... it is opposing the change because :- the induced current either decreases the increasing current or increases the decreasing current )
