How the current will be increased if the voltage is decreased? this is not so. according to ohm's law- V is proportional to I. so if load increases curent will be low. And the voltage also will do the same. :)

vi=constant
load i increases so voltage reduces to keep power constant
load i increases so voltage reduces to keep power constant

Its very easy. You just think about your mobile when you call or receive more [load] then your power, that is your battery will automatically decrease.

In Practical Applications battery voltage is lowered as load increases.

According to ohms law voltage is directly to propotional to current.
V= IR.
As as "R" increases so I will be less for const voltage supply. I less means we less (directly propotional).
V= IR.

For ideal constant voltage source, voltage willnot change. But in practical it decreses as load increases. And power need to be constant.

Prasanth answer is wrong. As current increase voltage also increase and vice versa.

It is just like a inverter when ever the power supply is on it will get charged and as soon as the power supply goes off the battery will be enabled and the stored charge will decay exponentially

Think practical as we increase load current will draws more rapidly.
