why current increases when voltage decreases in ac
system
Answer Posted / puneet kumar
In our system, current is flow from source to load..and
source is defined in term of VA rating only.(for more
KVA,MVA..)
Thus VA of source is fixed.
It means V X A = Constant.
or V = Constant / A
or V is inversly proportional to A.
Therefore current increses when voltage decreases in ac
system.
