As per ohm's law we can say that when we apply voltage difference V across a resistor of resistance R then current flow across the resistance at constant temperature is directly proportional to the applied voltage difference
this is given as
[tex]V = i R[/tex]
on rearranging the above equation we will have
[tex]i = \frac{V}{R}[/tex]
so the correct answer would be
I = V / R
