	RLC circuit - Wikipedia, the free encyclopedia
		An RLC circuit (sometimes known as resonant or tuned circuit) is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel.
		A RLC circuit is called a second-order circuit as any voltage or current in the circuit can be described by a second-order differential equation.
		In this circuit, the three components are all in series with the voltage source.

		For series resonance the condition of resonance is straightforward and it is characterized by minimum impedance and zero phase.
		The resonance of a series RLC circuit occurs when the inductive and capacitive reactances are equal in magnitude but cancel each other because they are 180 degrees apart in phase.
		The sharpness of the minimum depends on the value of R and is characterized by the "Q" of the circuit.

		The quantity Z is called the   impedance, it has units of ohms, and it plays the same role in AC circuits as resistance does in DC circuits.
		When a circuit is driven near its natural frequency, we say that it is being driven at resonance.
		If the circuit is not properly tuned, then it may pick up two stations equally well, an effect you have probably heard many times.

		The formulas on this page are associated with a series RLC circuit discharge since this is the primary model for most high voltage and pulsed power discharge circuits.
		In this case, once the switch closes and the voltage on the load resistor rises to match the capacitor voltage, both waveforms then essentially overlap and decay at the same rate since the voltage across the inductor is minimal.
		The circuit current is graphed in the second, lower plot and reaches its peak value at t=2L/R.This circuit is often desirable (if possible) with high voltage, energy storage capacitors since voltage reversals can frequently decrease the lifetime of the capacitor.

	The ideal series-resonant circuit
		Remember that current is the same in all parts of a series circuit because there is only one path for current.
		In summary, in a series-LC circuit with a source voltage that is above the resonant frequency (300 kHz in this example), impedance is higher than at resonance, current is lower, and the voltage drops across the reactances are lower.
		A typical series-LC circuit, then, has R as well as L and C. If our perfect (ideal) circuit has zero resistance, and a typical circuit has "some" resistance, then a circuit with a very small resistance is closer to being perfect than one that has a large resistance.

		The circuit begins in the zero state (inductor current = zero, capacitor voltage = zero), and the voltage source applies a unit voltage at time zero.
		The unusual position of the voltage source allows direct comparison of power for all four elements (placing the voltage source in the traditional position at left would foreshorten the power arrow width).
		t = 0 s: The series current remains zero immediately after applying the step input since the energy state of the inductor cannot change instantaneously, so the rightmost node of the resistor is pulled up to high potential.
