  2. RLC circuit - Wikipedia

    en.wikipedia.org/wiki/RLC_circuit

    An RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel. The name of the circuit is derived from the letters that are used to denote the constituent components of this circuit, where the sequence of the components may vary from RLC.

  3. Q factor - Wikipedia

    en.wikipedia.org/wiki/Q_factor

    Larger series resistances correspond to lower circuit Q values. For a parallel RLC circuit, the Q factor is the inverse of the series case: [21] [20] = = = [22] Consider a circuit where R, L, and C are all in parallel.

  4. Duality (electrical circuits) - Wikipedia

    en.wikipedia.org/wiki/Duality_(electrical_circuits)

    parallel – series (circuits) resistance – conductance; ... The use of duality in circuit theory is due to Alexander Russell who published his ideas in 1904. [1] [2]

  5. Electrical resonance - Wikipedia

    en.wikipedia.org/wiki/Electrical_resonance

    An RLC circuit (or LCR circuit) is an electrical circuit consisting of a resistor, an inductor, and a capacitor, connected in series or in parallel. The RLC part of the name is due to those letters being the usual electrical symbols for resistance, inductance and capacitance respectively. The circuit forms a harmonic oscillator for current and ...

  6. Series and parallel circuits - Wikipedia

    en.wikipedia.org/wiki/Series_and_parallel_circuits

    In a series circuit, the current that flows through each of the components is the same, and the voltage across the circuit is the sum of the individual voltage drops across each component. [1] In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents flowing through each ...

  7. Current divider - Wikipedia

    en.wikipedia.org/wiki/Current_divider

    Figure 1: Schematic of an electrical circuit illustrating current division. Notation R T refers to the total resistance of the circuit to the right of resistor R X.. In electronics, a current divider is a simple linear circuit that produces an output current (I X) that is a fraction of its input current (I T).

  8. LC circuit - Wikipedia

    en.wikipedia.org/wiki/LC_circuit

    A parallel resonant circuit can be used as load impedance in output circuits of RF amplifiers. Due to high impedance, the gain of amplifier is maximum at resonant frequency. Both parallel and series resonant circuits are used in induction heating. LC circuits behave as electronic resonators, which are a key component in many applications ...

  9. RL circuit - Wikipedia

    en.wikipedia.org/wiki/RL_circuit

    A resistor–inductor circuit (RL circuit), or RL filter or RL network, is an electric circuit composed of resistors and inductors driven by a voltage or current source. [1] A first-order RL circuit is composed of one resistor and one inductor, either in series driven by a voltage source or in parallel driven by a current source.
