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

Can you charge inductor with dc voltage or ac voltage?

Inductors are low pass devices, they conduct most easily at low frequencies. DC is the limiting case for low frequency AC: i.e. DC is the lowest possible AC frequency, zero Hz and thus conducts best through an inductor. Capacitors are high pass devices, they conduct most easily at high frequencies. Infinite frequency AC is the limiting case for high frequency AC. Infinity Hz would conduct best through a capacitor.

Is a capacitor sensitive to frequency?

yes, capacitive reactance is inversely proportional to frequency.

Why there are only RC filters and not RLC filters used with IC.why inductor is not used?

The inductor is a component which produces inductance. This inductance which opposes any change of current through it, so if any changes occurred in an IC the output will be changed. so inductor is not used.

What is the current limiting property in an iductor called?

The property that limits the current flow in an inductor is called inductive reactance. Inductive reactance increases with frequency, causing the inductor to resist changes in current flow. This property is a crucial part of inductor behavior in AC circuits.

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

Will an inductor work on DC?

An inductor cannot work in dc because the frequency is zero there by making the inductive reactance zero as a consequenceAnswerOf course an inductor can work in a d.c. circuit!

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

At what frequency is the reactance of a 0.450 inductor equal to that of a 2.50 capacitor?

943H

Why does the inductance of inductor varies with frequency?

It doesn't. the impedance of the inductor will, following the rule j*w*l, where l is inductance, w is frequency in radians and j is the imaginary number designating this a reactance, not resistance.

Why an inductor opposes the flow of alternating current?

A change in current through an inductor will induce a voltage into that conductor, the direction of which will always oppose that change in current. This is a natural phenomenon due to the conservation of energy.

How will be the outputs across the inductor and resistor if you keep the frequency of the input signal very low?

For a low frequency source, the voltage across the inductor tends to zero because its impedance is proportionnal to source frequency, whereas the voltage across the resistor tends to the voltage source value.

What does an electrical choke do?

A choke is an inductor. The impedance of an inductor is dependent on the frequency of the current flowing through it. The greater the frequency, the higher the impedance. Therefore an inductor when used as a choke blocks the flow of high frequency current (by presenting a high impedance), while allowing low frequency or direct current to flow through it. Its function is to block ("choke") high frequencies while passing low frequencies.

What increases when the frequency increases?

When frequency increases, the energy of the radiation increases. Additionally, the pitch of sound also increases with frequency. In electrical circuits, the impedance of a capacitor or inductor also increases with frequency.

How component size decreases when frequency decreases?

The impedance of a component (inductor or capacitor) will change with frequency - resistor impedances will not. Inductor impedance - j*w*L Capacitor impedance - 1/(j*w*C) L = inductance, C = capacitance, j = i = imaginary number, w = frequency in radians The actual inductance and capacitance does not change with frequency, only the impedance.
