  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. Open-circuit time constant method - Wikipedia

    Set the signal source to zero. Select capacitor C 2, replace it by a test voltage V X, and replace C 1 by an open circuit. Then the resistance seen by the test voltage is found using the circuit in the middle panel of Figure 1 and is simply V X / I X = R 1 + R 2. Form the product C 2 ( R 1 + R 2).

  4. Rectifier - Wikipedia

    en.wikipedia.org/wiki/Rectifier

    A motor-generator set, or the similar rotary converter, is not strictly a rectifier as it does not actually rectify current, but rather generates DC from an AC source. In an "M-G set", the shaft of an AC motor is mechanically coupled to that of a DC generator. The DC generator produces multiphase alternating currents in its armature windings ...

  5. Rise time - Wikipedia

    en.wikipedia.org/wiki/Rise_time

    Rise time is an analog parameter of fundamental importance in high speed electronics, since it is a measure of the ability of a circuit to respond to fast input signals. [8] There have been many efforts to reduce the rise times of circuits, generators, and data measuring and transmission equipment.

  6. Ripple (electrical) - Wikipedia

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

    Ripple (specifically ripple voltage) in electronics is the residual periodic variation of the DC voltage within a power supply which has been derived from an alternating current (AC) source. This ripple is due to incomplete suppression of the alternating waveform after rectification. Ripple voltage originates as the output of a rectifier or ...

  7. Relaxation oscillator - Wikipedia

    en.wikipedia.org/wiki/Relaxation_oscillator

    Relaxation oscillators are generally used to produce low frequency signals for such applications as blinking lights and electronic beepers. During the vacuum tube era they were used as oscillators in electronic organs and horizontal deflection circuits and time bases for CRT oscilloscopes; one of the most common was the Miller integrator circuit invented by Alan Blumlein, which used vacuum ...

    It quoted one source as saying no detailed discussions had yet taken place. The Telegraph added that any such visit would be unlikely to happen until at least 2026, given the schedule of King Charles.

  9. Electronic speed control - Wikipedia

    en.wikipedia.org/wiki/Electronic_speed_control

    The speed of the motor is varied by adjusting the timing of pulses of current delivered to the several windings of the motor. A generic ESC module rated at 35 amperes with an integrated eliminator circuit. Brushless ESC systems basically create three-phase AC power, like a variable frequency drive, to run brushless motors.
