Sample questions
In an L-C-R series circuit, the resonant frequency is $f_0$. If the inductance is doubled and capacitance is halved, the new resonant frequency will be:
A series RLC circuit is connected to an AC source. The impedance of the circuit is given by $Z = \sqrt{R^2 + (X_L - X_C)^2}$. Describe the condition for resonance in this circuit. The diagram shows a series RLC circuit with a resistor R, an inductor L, and a capacitor C connected to an AC voltage source. The general phasor diagram for this circuit shows current I along the x-axis, $V_R$ along I, $V_L$ leading I by 90 degrees, and $V_C$ lagging I by 90 degrees.
Average power in a L-C-R circuit depends upon
