Inductors and capacitors are called reactive elements in electric circuits.these reactive elements also offer resistance in the circuit termed as reactance
for inductor it is wL (-j)
for capacitor i is 1/wC (j)
where L,C and w are inductance , capacitance and frequency of the AC source respectively
when clubbed with resistance the the resultant of the resistance and reactance gives us the impedance of a circuit
if the impeadence(R=0) of the circuit is of inductor only then these are called as purely inductive circuits
if the impedence of the circuit is dominated by inductor ( wL > 1/wC ) even though the circuit has resistance and capacitor then these circuits are called inductive circuits

∙ 12y agoAn inductor has numerous functions in electric and electronic circuits; often it is named to reflect its function: e.g. 'choke', 'reactor', etc. The basic function of any inductor is to oppose any change in current -a changing current induces a voltage into the inductor which acts to oppose that change in current. In the case of a.c. circuits, an inductor will also act to limit the current -this behaviour increases with frequency, so it can be used to 'filter out' high-frequency signals, while allowing lower-frequency signals to pass.

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.
Why l is symbol for inductor?
inductor was invented by scientist lenz so it is denoted by l..
The resistance that an inductor poses to the flow of ac?
An inductor has two properties. The first is resistance(measured in ohms), which is due to the length, cross-sectional area, and resistivity of the conductor from which it is wound. The second is inductance (measured in henrys), which is due to the length of the inductor, its cross-sectional area, the number of turns, and the permeability of its core.The inductor's resistance limits the value of current flowing through the inductor. The inductor's inductance opposes any change in current.
In an AC circuit with only an inductor what will an increase in frequency do?
Inductor impedance is given by jwL, where w=2*pi*frequency. Therefore as the frequency increases the impedance of the inductor increases, causing a larger current flow and a larger power dissipation across the inductor
What type of inductor is installed in a circuit to impede the flow of ac of a frequency?
A: The inductor is called a RF choke
Why is an inductor used for?
what 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.
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 .
What is the purpose of inductor?
The fundamental purpose of an inductor is to store electrical energy in a magnetic field.
What is the symbol for an inductor?
The inductor symbol resembles a coil of wire of 3 to 5 turns.
Why l is symbol for inductor?
inductor was invented by scientist lenz so it is denoted by l..
Why inductor are used in CKT?
inductor is used in ckt because it will work as controling current device
