ytkms Posted March 2, 2007 Report Share Posted March 2, 2007 do you add it or find the difference ( subtract) ?X= XL+Xc or is it this X = XL- Xc or this X= Xc-XL"Pure reactancesPure inductive reactances (XL) and capacitive reactances (XC) simply add togetherwhen coils and capacitors are in series. Thus, X =XL+XC. In the RX plane, their vectorsadd, but because these vectors point in exactly opposite directions Quote Link to comment Share on other sites More sharing options...
walid Posted March 18, 2007 Report Share Posted March 18, 2007 Hiat a certain freq Xl = Xcso the series Z = 0and the parallel Z = infinityif you still confused, please choose some values to C and L and try calculate Z at different frequencies.

Gazza Posted March 20, 2007 Report Share Posted March 20, 2007 You can do it either way as long and you keep your signs consistent.Example (XT = Xc-XL)The reactance in the circuit is equal to the absolute value of Xc-XLIf the value of XT is positive, the reactance is capacitive, if it is negative, it is inductive.If you reverse the formula, the opposite is now true, positive values are inductive and negative numbers are positive.do you add it or find the difference ( subtract) ?X= XL+Xc or is it this X = XL- Xc or this X= Xc-XL Quote Link to comment Share on other sites More sharing options...
