v=ir
v=voltage
i=current
r=resistance
by ohm's law

v=ir
v=voltage
i=current
r=resistance

v=ir,when voltage increase current also increase.

voltage is difference between two potentials..........
current is flow of electrons in it...........
so with increase in current voltage increases.............

when I-current going through the conductor,proportional to 
the V-voltage

Voltage = current * resistance

power = voltage * Current

you want the relation between current and voltage. very 
fine. but in what element you want. it is different in 
different elements and devices. first you should be very 
clear before asking questions. ok. god bless you.

current: it is a series 
voltage : it is parallel
current : we cannot share current
voltage : it is possible to share

v=ir , but imp. point 2 b noted is current is directly
proportional 2 voltage not voltage......

Voltage is directly proportional to Current this
Proportionality is replaced by a constant called "Resistance"

 Hence V = IR

current is directly prapotional to applied voltage
