In an ac circuit the current in an inductor
The expression di/dtis one from calculus, meaning the rate of change of instantaneous current (i) over time, in amps per second. The inductance (L) is in Henrys, and the instantaneous voltage (e), of course, is in volts. Sometimes you will find the rate of instantaneous voltage expressed as “v” instead of … See more Inductors do not behave the same way as resistors do. Whereas resistors simply oppose the flow of current through them (by dropping a voltage directly proportional to the … See more But what does negativepower mean? It means that the inductor is releasing power back to the circuit, while a positive power means that it is absorbing power from the circuit. Since the positive and negative power cycles are … See more Angular velocity may be represented by the expression 2πf, or it may be represented by its own symbol, the lowercase Greek letter omega, which appears similar to our … See more An inductor’s opposition to change in current translates to an opposition to alternating current in general, which is by definition always changing in instantaneous magnitude and direction.

WebIllustrative Problem 1: An AC circuit is composed of a serial connection of: a resistor with resistance 50 Ω, a coil with inductance 0.3 H and a capacitor with capacitance 15 μF. The circuit is connected to an AC voltage source with amplitude 25 V and frequency 50 Hz. Determine the amplitude of electric current in the circuit and a phase difference between … WebThe magnitude of the reactive force opposing the flow of ac is measured in ohms. It can be expressed mathematically as: XL = 2πf L X L = 2 π f L. Where XL equals inductive reactance (inductor Impedance) in ohms, f equals frequency in hertz, L equals inductance in henrys, and π is approximately 3.1416.
