Inductive reactance is the property of an inductive coil that resists the change in alternating current (AC) through it and is similar to the opposition to direct current (DC) in a resistance.
22 wrz 2023 · The opposition to current flow through an AC Inductor is called Inductive Reactance and which depends lineally on the supply frequency. When connected to an AC supply, the current flowing through an inductive coil produces a self-induced emf opposing the emf that initially set up the current.
Chapter 1 Useful Equations And Conversion Factors. AC Circuit Equations. PDF Version. Inductive Reactance. Capacitive Reactance. Impedance in relation to R and X. Z L = R + jX L. Z C = R - jX C. Ohm’s Law for AC. Series and Parallel Impedances. All impedances must be calculated in complex number form for these equations to work. Resonance.
An inductor rated at 4 Henrys is subjected to a sinusoidal AC voltage of 24 volts RMS, at a frequency of 60 hertz. Write the formula for calculating inductive reactance (X L), and solve for current through the inductor.
Inductive reactance can be calculated using this formula: X L = 2πfL; The angular velocity of an AC circuit is another way of expressing its frequency, in units of electrical radians per second instead of cycles per second. It is symbolized by the lowercase Greek letter “omega,” or ω. Inductive reactance increases with increasing ...
Complex Impedance. The ratio of the voltage across a component to the current through it when both are expressed in complex notation. I=I0sin(ωt) I=I0ejωt.
The combined effect of resistance \(R\), inductive reactance \(X_L\), and capacitive reactance \(X_C\) is defined to be impedance, an AC analogue to resistance in a DC circuit. Current, voltage, and impedance in an RLC circuit are related by an AC version of Ohm’s law:
