  2. RLC circuit - Wikipedia

    en.wikipedia.org/wiki/RLC_circuit

    v. t. e. A series RLC network (in order): a resistor, an inductor, and a capacitor. Tuned circuit of a shortwave radio transmitter. This circuit does not have a resistor like the above, but all tuned circuits have some resistance, causing them to function as an RLC circuit. An RLC circuit is an electrical circuit consisting of a resistor (R ...

  3. RC circuit - Wikipedia

    en.wikipedia.org/wiki/RC_circuit

    A resistor–capacitor circuit (RC circuit), or RC filter or RC network, is an electric circuit composed of resistors and capacitors. It may be driven by a voltage or current source and these will produce different responses. A first order RC circuit is composed of one resistor and one capacitor and is the simplest type of RC circuit.

  4. RC time constant - Wikipedia

    en.wikipedia.org/wiki/RC_time_constant

    RC time constant. The RC time constant, denoted τ (lowercase tau), the time constant (in seconds) of a resistor–capacitor circuit (RC circuit), is equal to the product of the circuit resistance (in ohms) and the circuit capacitance (in farads): It is the time required to charge the capacitor, through the resistor, from an initial charge ...

  5. Capacitance - Wikipedia

    en.wikipedia.org/wiki/Capacitance

    In general, capacitance is a function of frequency. At high frequencies, capacitance approaches a constant value, equal to "geometric" capacitance, determined by the terminals' geometry and dielectric content in the device. A paper by Steven Laux [27] presents a review of numerical techniques for capacitance calculation.

  6. Equivalent series resistance - Wikipedia

    en.wikipedia.org/wiki/Equivalent_series_resistance

    Equivalent series resistance. Capacitors and inductors as used in electric circuits are not ideal components with only capacitance or inductance. However, they can be treated, to a very good degree of approximation, as being ideal capacitors and inductors in series with a resistance; this resistance is defined as the equivalent series ...

  7. Capacitor - Wikipedia

    en.wikipedia.org/wiki/Capacitor

    When a parallel-plate capacitor is filled with a dielectric, the measurement of dielectric properties of the medium is based upon the relation: = ′ ″ = = (), where a single prime denotes the real part and a double prime the imaginary part, Z(ω) is the complex impedance with the dielectric present, C cmplx (ω) is the so-called complex ...

  8. Ohm's law - Wikipedia

    en.wikipedia.org/wiki/Ohm's_law

    Ohm's law states that the electric current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, [1] one arrives at the three mathematical equations used to describe this relationship: [2] where I is the current through the conductor, V ...

  9. RL circuit - Wikipedia

    en.wikipedia.org/wiki/RL_circuit

    t. e. 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.
