riders59rohan Posted August 12, 2008 Share Posted August 12, 2008 The capacitor's resistance i.e the resistance offered by the material from which capacitor was made and not the resitance offered by air gap between the capacitor should it be shown in the circuit either in series or in parallel to the capacitor.

waitforufo Posted August 12, 2008 Share Posted August 12, 2008 This resistance is generally referred to as Equivalent Series Resistance (ESR). See http://wiki.xtronics.com/index.php/Capacitors_and_ESR Link to comment Share on other sites More sharing options...
John Cuthber Posted August 13, 2008 Share Posted August 13, 2008 Both. If you charge a capacitor then wait a long time and measure the voltage you will find that it's less than you charged it to. This leakage of charge can be modeled as a (large) resistance in parallel with the capacitor. The ESR limits how fast you can discharge a capacitor (neglecting stray inductance) and the leakage resistance limits how slowly you can discharge it.
