Lewis Posted November 5, 2003 Report Share Posted November 5, 2003 Dear all, i would like to ask a question about a RC circuit.The supply is connected to a capacitor which is parallel to a resistor, then connect them to a high voltage discharge lamp.There is a question: what is the functions of the capacitor and resistor. Thanks Link to comment Share on other sites More sharing options...
ng Posted June 18, 2005 Report Share Posted June 18, 2005 as i understand it, a capacitor stores charge(energy in its electric field).it acts like a battery and when there is a path for discharging it discharges. Link to comment Share on other sites More sharing options...
Matt Posted July 12, 2007 Report Share Posted July 12, 2007 When power is removed from the Circuit, The Cap will discharge through the Res. In accordance with the Time Constant RC....................... Matt "Its easier to get Forgiveness than Permission" Never ever say to a customer "It Can't Do That" Because It CAN !!

marke Posted July 12, 2007 Report Share Posted July 12, 2007 The R-C network is commonly referred to as a snubber network and is designed to limit the rate of rise of voltage. This will help to reduce transient voltages with the transient energy absorbed in the resistor. Commonly employed around arcing contacts etc to limit the arcing and to prolong the contact life.
