What is inductive reactance Class 12?

Inductive reactance is the name given to the opposition by an inductor to a changing current flow in the circuit. This impedance value is measured in ohms, just like the resistance. The inductive reactance is represented by XL and measured in ohms (Ω).

What is inductive and capacitive reactance?

The reactance in the magnetic field resists change in the current whereas, in the electric field, the reactance will resist the change in voltage. With the increase in frequency, capacitive reactance is decreased, and inductive reactance is increased.

What is inductance and inductive reactance?

Inductance is the property of a circuit to oppose any change in current and is measured in henries. Inductive reactance is a measure of how much the countering emf in the circuit will oppose current variations.

What is the reason for inductive reactance?

Inductive reactance It is this change in magnetic field that induces another electric current to flow in the same wire (counter-EMF), in a direction such as to oppose the flow of the current originally responsible for producing the magnetic field (known as Lenz’s Law).

What is inductive reactance and its unit?

Inductive reactance (XL)—It is the effective opposition offered by the inductor to the flow of current in the circuit. Its S.I. unit is ohm.

What is inductive and capacitive?

Compared to resistive loads, inductive load current peaks after voltage. Consequently, inductive coils produce lagging power factors. Capacitive load elements use capacitors that store electrical charge. They resist changes in voltage, which causes current to peak before voltage during each electrical cycle.

What is inductive reactance and capacitive reactance Class 12?

Inductive reactance XL : The quantity ωL plays the same role as the resistance R in resistive circuit. This is the resistance offered by the capacitor, called capacitive reactance (XL ). It measured in ohm. XL = ωL.

What is difference between inductance and induction?

As nouns the difference between induction and inductance is that induction is an act of inducting while inductance is the property of an electric circuit by which a voltage is induced in it by a changing magnetic field.

Is inductive reactance same as inductance?

More specifically, inductive reactance (Xl) is just Inductance (L) times angular frequency (w). So if you increase the frequency of the current running through your inductor, the reactance will increase, but the inductance will stay the same.

What is the formula of inductive reactance?

Inductive reactance is defined as:(10-4)XL=_ωL=2πfLwhere XL is the inductive reactance, ω is the angular frequency, f is the frequency in Hertz, and L is the inductance.

How do you derive inductive reactance?

Inductive reactance equation derivation Inductive reactance is the opposition offered by the inductance to the current flow. The Inductive reactance is directly proportional to the frequency ‘ f ‘ and the inductance ‘ L’. The value of inductive reactance is measured in ohms.

What is difference in resistance and reactance?

The resistance is the obstacle in the flow of current in an electrical circuit due to resistor.

Resistance is the property associated with both ac and dc circuit.

Pure resistors generate resistance.

Resistance is associated with the real part of the impedance.

The difference in phase between voltage and current in a purely resistive circuit is 0⁰.

What is the reactance for an inductor and capacitor?

Reactance has two types; inductive and capacitive reactance . As the name suggests, the inductor provided opposition is called inductance reactance where opposition by the capacitor is called capacitive reactance. Both are denoted by capital letter “X” with a subscript of “L” for the inductor and “C” for the capacitor. It is also measured in “Ohms”. Reactance changes with a change in frequency. Impedance : Any opposition to current an in AC circuit is called impedance, which

What is meant by reactance?

Reactance, denoted X, is a form of opposition that electronic components exhibit to the passage of alternating current (alternating current) because of capacitance or inductance. In some respects, reactance is like an AC counterpart of DC (direct current) resistance.

What is inductance reactance?

Inductive reactance is a property exhibited by an inductor, and inductive reactance exists based on the fact that an electric current produces a magnetic field around it.
