someone help... i need value of capasitor for power factor correction for powerline 1300 W
 

you need to calculate KVA by multiplying V and I,

Now you have KW and KVA->so you easily find KVAR from pithagoras low.

KVAR^2=KVA^2-KW^2.(^2=square).

Now, if KVAR=200,you need 200 var in capaciteve side for balance so you can calculate it by V*I*Xc=KVAR (Needed).

so your Xc=KVAR/V*I.
