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.
Solution: (a) The impedance of a series RLC circuit is given by. 2 = Z R + ( X − X )2. L C. where . X = ω L. L. and . = ω C. (1.1) (1.2) (1.3) are the inductive reactance and the capacitive reactance, respectively. Since the general expression of the voltage source is V ( t ) = V.
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 lower-case Greek letter “omega,” or ω. Inductive reactance increases with increasing ...
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.
