I dunno to tell with respect to ohm's law.
The thing is lik this. When it is short circuited, (it means the ends are connected by a conductor) there is no resistance(ideally infinite) available to stop the flow of electrons. it means current flow is very high(ideal case- infinity).since the charges are moving faster there is no potential difference that exists across the points, hence voltage(ie potential difference) is 0

As per ohms law V = IR agreed, but here V you can say as source and v is voltage drop across R, so don't confuse between V and v, here V is source and R is resistance so if R = 0 ohms then v drop across R is o v but due to V source current flows maximum we can say as short circuit current.

According to ohm's law:-
V=IR
I=V/R
Current is a inversely proportional to the resistance when resistance is 0(short circuit resistance is always 0) the current in a circuit is infinity.
V=IR
I=V/R
Current is a inversely proportional to the resistance when resistance is 0(short circuit resistance is always 0) the current in a circuit is infinity.

hey in short circuits voltage is zero...according to ohms law v=IR, I will be zero..but it is max. how it is?

Or with ohm's law itself we an say like:
V=IR
Here I=infinite; R=0
So, V=0.
V=IR
Here I=infinite; R=0
So, V=0.

With ohms law we is directly proportional to I irrespective of are then how would be v=0?

As the resistance zero in short circuit.SO, the current flow is maximum.

Yes, I can understand current flow is max according to ohms law.

Short circuit means r=0. So if r is 0 that means i-maxm, so B.
