what is the min and max ohmic resistance for the earthing
rod installed for lighting poles for street light network
Due to ferranti effect which power increases at the receiving end?active power or reactive power?
is power factor correction related with vector group of transformer i.e:Dyn11?
at meter room 50 hrc switch installed,but there are not get earthing proper,so what happen?and 11kv transformer out put going in to hrc main 400a three nog each? so earthing is require for all switch? (some customer made earthing at there home.)

Can u explain : how capacitor act when the supply is given is a.c and d.c. I know that when d.c supply is given then the capacitor charges and becomes open circuited. But please say about when a.c is given. I have seen that when a.c supply is given ,it charges and discharges, But when we plug in capacitor to our daily supply and take it out ,then we join those wires spark will appear,which seems charge is present ,but when a.c is given it should charge and discharge
