  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

    So a much wider frequency range can be covered by a given variable capacitor in an RC oscillator. For example, a variable capacitor that could be varied over a 9:1 capacitance range will give an RC oscillator a 9:1 frequency range, but in an LC oscillator it will give only a 3:1 range. Some examples of common RC oscillator circuits are listed ...

  4. 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):

  5. RLC circuit - Wikipedia

    en.wikipedia.org/wiki/RLC_circuit

    The tuning application, for instance, is an example of band-pass filtering. The RLC filter is described as a second-order circuit, meaning that any voltage or current in the circuit can be described by a second-order differential equation in circuit analysis. The three circuit elements, R, L and C, can be combined in a number of different ...

  6. Time constant - Wikipedia

    en.wikipedia.org/wiki/Time_constant

    Similarly, in an RC circuit composed of a single resistor and capacitor, the time constant (in seconds) is: = where R is the resistance (in ohms ) and C is the capacitance (in farads ). Electrical circuits are often more complex than these examples, and may exhibit multiple time constants (See Step response and Pole splitting for some examples.)

  7. Open-circuit time constant method - Wikipedia

    en.wikipedia.org/wiki/Open-circuit_time_constant...

    Figure 1: Simple RC circuit and auxiliary circuits to find time constants. Figure 1 shows a simple RC low-pass filter. Its transfer function is found using Kirchhoff's current law as follows. At the output, = , where V 1 is the voltage at the top of capacitor C 1. At the center node:

  8. Electronic oscillator - Wikipedia

    en.wikipedia.org/wiki/Electronic_oscillator

    In an RC oscillator circuit, the filter is a network of resistors and capacitors. [2] [4] RC oscillators are mostly used to generate lower frequencies, for example in the audio range. Common types of RC oscillator circuits are the phase shift oscillator and the Wien bridge oscillator.
