If V is directly proportional to I then can I be directly proportional to V???

Dear student,

According to Ohm's law, at constant temperature and physical parameters (like length and area) the potential difference is directly proportional to current. 

V=IR  where V= Voltage, I= Current and R= Resistance.

By looking at the ohm’s law we understand that,
I=VR
 

So you can say, numerically I is proportional to V.

It depends on whose respect you are talking with or which parameter (current or voltage) you are controlling. 
But conventionally, potential difference drives the current, that's why it is not correct to state Ohm’s law the other way round. But if you are talking from mathematical aspect, you can say I is proportional to V. 

Regards,
