if battries are fully charged and kept off,they will loose
the charge even though they are not supplying the load.So
they they kept under continous charge.this is known
as "trickle charging"

Answer / babu sundaran

Trickle charging, means charging a fully charged battery
under no-load at a rate equal to its self-discharge rate,
thus enabling the battery to remain at its fully charged level

To know the self discharge rate of battery refer the data
sheet of battery manufacturer .

We say that if voltage in a power system is increased,for a constant power the current will decrease (by P=VI). isn't this in disagreement with the ohms law(I propotional V;resistant const.).Since the resistance of transmission lines remains constant,shouldn't inc in voltage cause inc in current across the transmission line? I have read many articles across the net but still couldn't this figure this out. :( Guyz plz assist me with dis..:)..
