In the RLC series circuit, there is a resonant frequency where the inductive reactance equals capacitive reactance. The average power versus angular frequency plot for a RLC circuit has a peak …

Lecture 18: AC Circuits. Power and energy; Resonance. Filters. 18.1 AC circuits: Recap and summary. Last time, we looked at AC circuits and found that they are quite simple to analyze provided we follows some simple rules: 1. Work with complex valued voltages and currents.
completes with chapters on AC power, resonance, and introductions to polyphase systems and magnetic circuits. Each chapter begins with a set of learning objectives and concludes with practice exercises that are generally
12.2 Simple AC circuits Before examining the driven RLC circuit, let’s first consider the simple cases where only one circuit element (a resistor, an inductor or a capacitor) is connected to a sinusoidal voltage source. 12.2.1 Purely Resistive load Consider a purely resistive circuit with a resistor connected to an AC generator, as shown
Resonance in AC Circuits. By Dr. Sanjay Vidhyadharan. Zmin = R at Resonant Frequency where XL = XC. Imax = V/R. QUALITY FACTOR (Q) The “sharpness” of the resonance in a resonant circuit is measured quantitatively by the quality factor Q.
Resonance. AC Electric Circuits. PDF Version. Question 1. The Q factor of a series inductive circuit is given by the following equation: Q = X L. R series. Likewise, we know that inductive reactance may be found by the following equation: X L = 2 πf L. We also know that the resonant frequency of a series LC circuit is given by this equation: f r =
