I know the HSC is over but this has been haunting me for months.

Its been like a splinter in my mind.

My question relates to superconductors.

alright.

so a superconductor below its critical tempertaure has no resistance (zero resistance) to the flow of electricity.

And because it has zero resistance, it allows high voltages to be produced.

But, in the V = IR relationship, according to me, if R is zero, then V is zero.

Can someone explain my hypothesis or have I revolutionised modern physics?

That equation applies only to the conductors that exhert resistance on the electrons which flow through them. This equation would also apply to the superconductor if it was not cooled to its critical temperature....

So yeh, you can't really apply the formula to the application of superconductors when at their critical temp. The concept of zero resistance within a superconductor is more technical than the BCS theory, its pretty advanced physics... Somethnig to do with Bonons if I remember correctly :p
