  2. 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.

  3. RC oscillator - Wikipedia

    en.wikipedia.org/wiki/RC_oscillator

    Another common design is the "Twin-T" oscillator as it uses two "T" RC circuits operated in parallel. One circuit is an R-C-R "T" which acts as a low-pass filter. The second circuit is a C-R-C "T" which operates as a high-pass filter. Together, these circuits form a bridge which is tuned at the desired frequency of oscillation.

  4. Circuit topology (electrical) - Wikipedia

    en.wikipedia.org/wiki/Circuit_topology_(electrical)

    Circuit diagram of a ladder network low-pass filter: a two-element-kind network. Comprehensive cataloguing of network graphs as they apply to electrical circuits began with Percy MacMahon in 1891 (with an engineer-friendly article in The Electrician in 1892) who limited his survey to series and parallel combinations. MacMahon called these ...

  5. RC time constant - Wikipedia

    en.wikipedia.org/wiki/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):

  6. Network analysis (electrical circuits) - Wikipedia

    en.wikipedia.org/wiki/Network_analysis...

    Two terminals where the current into one is identical to the current out of the other. Circuit: A current from one terminal of a generator, through load component(s) and back into the other terminal. A circuit is, in this sense, a one-port network and is a trivial case to analyse.

  7. Phase-shift oscillator - Wikipedia

    en.wikipedia.org/wiki/Phase-shift_oscillator

    The two resistors R and three capacitors C form the RC phase-shift network which provides feedback from collector to base of the transistor. Resistor R b provides base bias current. Resistor R c is the collector load resistor for the collector current. Resistor R s isolates the circuit from the external load. [3]

  8. Electronic circuit - Wikipedia

    en.wikipedia.org/wiki/Electronic_circuit

    A circuit diagram representing an analog circuit, in this case a simple amplifier. Analog electronic circuits are those in which current or voltage may vary continuously with time to correspond to the information being represented. A simple schematic showing wires, a resistor, and a battery

  9. Negative resistance - Wikipedia

    en.wikipedia.org/wiki/Negative_resistance

    An I–V curve, showing the difference between static resistance (inverse slope of line B) and differential resistance (inverse slope of line C) at a point (A).. The resistance between two terminals of an electrical device or circuit is determined by its current–voltage (I–V) curve (characteristic curve), giving the current through it for any given voltage across it.
