If the current is directly proportional to potential difference, then why the is V=IR not I=VR.....

What does infinite resistance mean in circuit.

Ideally we have zero resistance does that mean that if I apply an potential difference V, it will come to zero (because of ohm law)

V=IR

BUT R=0

V=0

The potential difference across a cell of emf E and internal resistance r is

Q. At absolute zero temperatures ..... Materials become superconductive..... Electricity pass through them without any resistance ..... According to 'V=IR' , R becomes zero ,then if resistance becomes zero do u think that any kind of potential difference exists???? And if not ...how can electrons travel through a conductor??? at such weird temperatures?

Q. Which among the following is correct, where I = current, V = Potential difference & R = Resistance?
