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

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

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.

In real time, any running with any load for racer will decrease his real speed due to weight.

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.

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

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. :)

Power= Voltage*current
Increase in Load means Increase in load current.
So if Current increases, Voltage has to be decreased so that total power remains constant( V*I= constant).
Increase in Load means Increase in load current.
So if Current increases, Voltage has to be decreased so that total power remains constant( V*I= constant).

1)Voltage and current cannot be increased simultaneously
2)As load increases current also increases
3)So voltage has to be decreased
2)As load increases current also increases
3)So voltage has to be decreased
