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 inductor block ac and pass dc?
When your circuit starts up, your inductor creates an electrical current in the opposite direction. With dc, this effect vanished after the circuit is started. With ac, the current keeps starting and stopping so the inductor keeps creating a current in the opposite direction.
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
Why do the voltage drops of an inductor and a lamp in a series ac circuit not equal the applied voltage?
The voltage is greater than the applied voltage, why?
What cause the voltage t lead current in an ac circuit?
Voltage leads current or, more specifically current lags voltage, in an inductive circuit. This is because an inductor resists a change in current.

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.

Capacitor inductor circuit which smooth out rectified ac voltage are known as?
filter circuits
What is an ac reactor?
A reactor in an AC circuit is basically an inductor which will filter spikes in source voltage. See the related link.
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. ======================

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 is the bahaviorS of the INDUCTOR in ac supply?
Because of Ac supply, current lags voltage by 90 in Inductor.
Why do the voltage drops of an inductor and a lamp in a series ac circuit not equal the applied voltage?
The voltage is greater than the applied voltage, why?
Does inductor allow ac to pass through it?
Yes, with some difficulty. You can think of an inductor as a kind of "AC resistor"in a way. The higher the frequency of the AC, the more difficulty it has passingthrough the inductor.If you apply AC voltage across an inductor, whereV = voltage of the ACf = frequency of the ACL = inductance of the inductor,then the AC current through the inductor isI = V/2 pi f L
What is driven RL circuit?
A driven RL circuit is a circuit that contains a resistor (R) and an inductor (L) connected in series with an external source of alternating current (AC) or voltage. The external source provides energy to the circuit, driving the current through the inductor and resistor. This circuit can exhibit interesting behavior such as resonance and phase shifts due to the interplay between the inductive and resistive components.
What cause the voltage t lead current in an ac circuit?
Voltage leads current or, more specifically current lags voltage, in an inductive circuit. This is because an inductor resists a change in current.
