The ac circuit shown in Figure 15.4.1 15.4. 1, called an RLC series circuit, is a series combination of a resistor, capacitor, and inductor connected across an ac source. It produces an emf of ω t.

To analyze a series RLC circuit, follow the same approach as for series RL and RC circuits. However, this time, consider the magnitudes of both XL (inductive reactance) and XC (capacitive reactance) to find the overall circuit reactance.
The series RLC circuit has a sinusoidal response that varies with frequency, ƒ. This is because the inductive and capacitive reactances, XL and XC, are functions of the supply frequency.
In a series RLC circuit, the current is taken as the reference vector. Therefore, the current lags the source voltage by 51.8°, which means the phase angle is lagging. This is confirmed by the mnemonic expression “ELI”.
The voltages across the circuit elements add to equal the voltage of the source, which is seen to be out of phase with the current. An RLC series circuit has a 40.0Ω resistor, a 3.00 mH inductor, and a 5.00μF capacitor.
Instead of analysing each passive element separately, we can combine all three together into a series RLC circuit.
Consider an electrical circuit containing a resistor, an inductor, and a capacitor, as shown in Simple Harmonic Motion Figure 9. Such a circuit is called an RLC series circuit. RLC circuits are used in many electronic systems, most notably as tuners in AM/FM radios.The tuning knob varies the capacitance of the capacitor, which in turn tunes the radio.

Perhaps the first practical issue we face is determining the effective impedance of an RLC series loop. For starters, resistors in series simply add. Reactances also add but we must be careful of the sign. Inductive reactance and capacitive reactance will partially cancel each other. Thus, the impedance in rectangular form is the sum of the ...
