audioguru Posted May 24, 2007 Report Share Posted May 24, 2007 A reactance doesn't dissipate power. The tiny amount of resistance inside it dissipates a small amount of power.The reactance charges and discharges with AC current which is called "apparent power".Apparent power is explained in articles in Google about Power Factor.

bodonkudelly Posted May 28, 2007 Author Report Share Posted May 28, 2007 Thank Audioguru.But , could we measuring it ??? ::) Quote Link to comment Share on other sites More sharing options...
AN920 Posted May 28, 2007 Report Share Posted May 28, 2007 You need a varmeter that measures the the product effective [(Voltage x Current) x Sin (angle between V and I)] . Reading will only obtained when V and I have a a certain phase difference. Readings for 0 deg and 180 degree phase difference will read zero.
