Re: Zero Ohms = Mathematically Incorrect

Hi:

If a conductor has zero resistance, then what is the amperage of a
current flowing though it?

Amperage = voltage/resistance

If the resistance is zero, then the amperage is something that math
cannot explain. Anything divided by zero is an "error" when calculated.

How to solve this puzzle?


Thanks,

Radium

Yes, but E=IR, so if you have no resistance (R) then the voltage (E) =
zero and the current (I) is undefined since I=E/R and if E and R are
both zero, the current (I) can be a very large number, since 0/0 =
infinity. So what is the current in that case?

Another thought is the current and voltage in a LC tank circuit. If the
current reaches a peak at the same time the voltage goes to zero, and
visa versa, what is the current in the LC circuit when the voltage is
zero?
