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. XL =2p x f x L. L = the inductance value of the coil in henries.
How do you find XC?
Capacitive reactance is defined as:(10-1)Xc=1/ωC=1/2πfCwhere XC is the capacitive reactance, ω is the angular frequency, f is the frequency in Hertz, and C is the capacitance.
What do you mean by reactance?
In electric and electronic systems, reactance is the opposition of a circuit element to the flow of current due to that element’s inductance or capacitance. Greater reactance leads to smaller currents for the same voltage applied.
How does an inductor affect an AC circuit?
Hence, when a sinusoidal voltage is applied to an inductor, the voltage leads the current by one-fourth of a cycle, or by a 90º phase angle. Current lags behind voltage, since inductors oppose change in current. Changing current induces an emf. This is considered an effective resistance of the inductor to AC.
What is inductor and how it works in AC circuit?
An Inductor is usually a coil of wire that sets up an alternating magnetic field around it when an alternating current flows through it . Inductance is the property of an inductor that opposes the change in current. The AC circuit behavior with inductor is entirely different from the DC circuit.
What is the effect of capacitor in AC circuit?
We know that the current flowing through the capacitance in AC circuits is in opposition to the rate of change of the applied voltage but just like resistors, capacitors also offer some form of resistance against the flow of current through the circuit, but with capacitors in AC circuits this AC resistance is known as …
Can I use a capacitor with a higher UF rating?
Start capacitors typically range from 20-30 uf up to 250-300 uf. You can safely substitute a higher voltage rating capacitor in place of a lower one, but never put a lower voltage capacitor if the original was a higher voltage—These capacitors are used on many Capacitor Start/Capacitor Run Motors.
