  2. Brinkley stick - Wikipedia

    en.wikipedia.org/wiki/Brinkley_stick

    A Brinkley stick is a safety device used to discharge high voltage capacitors and ensure HT (high voltage) electrical circuits are discharged.The tool consists of a hook attached to the end of an insulated rod.

  3. RC time constant - Wikipedia

    en.wikipedia.org/wiki/RC_time_constant

    It is the time required to charge the capacitor, through the resistor, from an initial charge voltage of zero to approximately 63.2% of the value of an applied DC voltage, or to discharge the capacitor through the same resistor to approximately 36.8% of its initial charge voltage.

    en.wikipedia.org/wiki/Rechargeable_battery

    Ultracapacitors – capacitors of extremely high value – are also used; an electric screwdriver which charges in 90 seconds and will drive about half as many screws as a device using a rechargeable battery was introduced in 2007, [47] and similar flashlights have been produced.

  5. Clamper (electronics) - Wikipedia

    en.wikipedia.org/wiki/Clamper_(electronics)

    The capacitor cannot be made arbitrarily large to overcome load discharge. During the conducting interval, the capacitor must be recharged. The time taken to do this is governed by a different time constant, this time set by the capacitance and the internal impedance of the driving circuit. Since the peak voltage is reached in one quarter cycle ...

  6. Capacitor discharge sintering - Wikipedia

    en.wikipedia.org/wiki/Capacitor_Discharge_Sintering

    Capacitor discharge sintering (CDS) [1] is an electric current assisted sintering (ECAS) technique. [2] The technique is based on storage of electrostatic energy in a high voltage capacitor bank, and discharge into the sintering apparatus at low voltage (<30 V) and high current through step-down transformers on a pre-compacted powder compact which is kept under pressure.

  7. Bleeder resistor - Wikipedia

    en.wikipedia.org/wiki/Bleeder_resistor

    In electronics, a bleeder resistor, bleeder load, leakage resistor, capacitor discharge resistor or safety discharge resistor is a resistor connected in parallel with the output of a high-voltage power supply circuit for the purpose of discharging the electric charge stored in the power supply's filter capacitors when the equipment is turned off, for safety reasons.

  8. Discharger - Wikipedia

    en.wikipedia.org/wiki/Discharger

    A discharger in electronics is a device or circuit that releases stored energy or electric charge from a battery, capacitor or other source. Discharger types include: metal probe with insulated handle & ground wire, and sometimes resistor (for capacitors) resistor (for batteries) parasitic discharge (for batteries arranged in parallel)

  9. Dielectric absorption - Wikipedia

    en.wikipedia.org/wiki/Dielectric_absorption

    Dielectric absorption is the name given to the effect by which a capacitor, that has been charged for a long time, discharges only incompletely when briefly discharged.. Although an ideal capacitor would remain at zero volts after being discharged, real capacitors will develop a small voltage from time-delayed dipole discharging, [1] a phenomenon that is also called dielectric relaxation ...
