AI Thread Summary
In an ideal circuit with zero resistance, connecting an ideal battery leads to the conclusion of infinite current, which is deemed a meaningless scenario. The voltage at the terminals of the battery remains defined, but the current becomes undefined due to the lack of resistance. The discussion highlights that while the situation is theoretically interesting, it does not align with physical reality. Kirchhoff's voltage law cannot be applied in this context because the premise is considered nonsensical. Ultimately, the thread was closed due to the flawed premise of the question.

If an ideal battery of zero internal resistance is connected to a conductor having no resistance, what should be the current through the circuit (as in schematic) ?

The question is meaningless, really. It would be infinite current, but so what? It is not a physical situation.
 
The ideal voltage source defines the voltage at its terminals to be V. If the conductor connecting its terminals has zero resistance, the voltage between its ends is zero.

I would say, if V is nonzero, the current through the voltage source is undefined.

No doubt its not a physical situation but at least it is a proper theoretical case which can be considered from a theoretical point of view....in that case I have some questions...how can Kirchhoff's voltage law be applied to this circuit...

It cannot, because the premise is nonsense. We do not waste people's time here at the PF with threads that start with a false premise. Thread is closed.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...

Thread 'Why measure the speed of light in one direction?'

It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
