Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I'm currently doing an A level course in Physics, so this thought struck me then.

I was looking at a simple problem, when a thought struck me, if V=I/R and at absolute zero (0 kelvin) there is no resistance, what happens to the voltage?

In other words, V=I/0 I know that you cannot divide by zero so I asked a staff member and he said at that temperature there is no Voltage at all, the current just keeps going round and round.

So does this mean that 0=I/0? So is the answer dividing by zero = zero??

Sorry if I have posted in the wrong forum, but I wasn't sure where it was supposed to go.

Regards.
