Document Summary

Resonance and coupled circuits: series and parallel resonance their frequency. Response: quality factor and bandwidth, self and mutual inductance, coefficient of coupling, tuned circuits, series and parallel resonance their frequency. The frequency at which the reactance of the inductance and the capacitance cancel each other is the resonant frequency (or the unity power factor frequency) of this circuit. Since i = vr /r, then the current i can be studied by studying the voltage across the resistor. !2-!1= r/l are called the half power frequencies or the 3 db frequencies, i. e the frequencies at which the value of im equals the maximum possible value divided by = 1. 414. Of interest here in how the steady state amplitude and the phase angle of the output voltage v0 vary with the frequency of the sinusoidal voltage source: quality factor and bandwidth. Reactive components such as capacitors and inductors are often described with a figure of merit called q.
