How is inductive reactance calculated in AC circuits?
The formula for calculating the inductive reactance of a coil is: inductive reactance, or XL, is the product of 2 times p (pi), or 6.28, the frequency of the ac current, in hertz, and the inductance of the coil, in henries. A coil with an inductance of 0.3 henries is connected to a 120 volt, 60 hertz AC circuit.
What is the formula of inductance in AC circuit?
AC Inductance with a Sinusoidal Supply This simple circuit above consists of a pure inductance of L Henries ( H ), connected across a sinusoidal voltage given by the expression: V(t) = Vmax sin ωt. When the switch is closed this sinusoidal voltage will cause a current to flow and rise from zero to its maximum value.
What is inductive reactance in an AC circuit?
When an alternating or AC voltage is applied across an inductor the flow of current through it behaves very differently to that of an applied DC voltage. In other words, an inductors electrical resistance when used in an AC circuit is called Inductive Reactance.
Which is the correct formula for inductive reactance?
Definition: Inductive reactance is the opposition offered by the inductor in an AC circuit to the flow of ac current. It is represented by (X L ) and measured in ohms (Ω). Inductive reactance is mostly low for lower frequencies and high for higher frequencies.
How is reactance of capacitor and inductor measured?
Reactance is the opposition offered by capacitor and inductor in a circuit to the flow of AC current in the circuit. It is quite similar to resistance but reactance varies with the frequency of the ac voltage source. It is measured in ohms.
How does inductive reactance affect the flow of current?
An inductor resists the flow of an alternating current as a result of its inductance. Any inductor resists a change in current as a result of Lenz’s Law. The degree to which the inductor impedes the flow of current is due to its inductive reactance.
What is the difference between reactance and capacitive reactance?
What is Reactance? 1 Inductive Reactance (X L) Definition: Inductive reactance is the opposition offered by the inductor in an AC circuit to the flow of ac current. 2 Solved Problems. 3 Capacitive Reactance. 4 Solved Problems: Problem 1: Find out the capacitive reactance (Xc) for an AC source of 100v and 50 Hz by a capacitor of c = 20 μF.
