Kirchoff's Law With Battery Only

AI Thread Summary
The discussion centers on the application of Kirchhoff's law in a hypothetical scenario involving a resistance-free wire and a battery with no internal resistance. It is clarified that such a situation is not physically realistic, as it would imply infinite current, which is impossible. Real voltage sources always have some internal resistance that limits current flow. When connecting a battery to a superconducting wire, the current is still governed by the finite internal resistance of the voltage source. Thus, the original question about applying Kirchhoff's law in this context is deemed inappropriate.

Hello,
If one had a resistance free wire and a battery with no internal resistance, how would Kirchoff's law be applied if the terminals of the battery were connected by the wire? Is this even an appropriate question? I know/believe current would be at infinity. I am still trying to fully understand voltage, but because it is a conservative electric field, wouldn't the equation still be equal to zero?

Thank you

It is not an appropriate question. Anything that generates infinite current is non-physical.

Any real voltage source has a finite internal resistance. So if you connect it to a superconducting wire, the current is determined by the finite internal resistance of the voltage source.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
