How would one scientifically prove that there's no current flowing through this circuit?
I got into an argument with "that guy" who thinks that the universe doesn't exist when you're not looking at it. He also thinks it's plausible that a small amount of current could flow through this circuit, but attempting to measure how much would involve breaking the circuit and at the moment all the current would magically vanish.
the answer is litterally magnets
actually, throw a magnet through the loop and current will flow in it as long as the magnet is moving
you could measure it without breaking the circuit by using a clamp on ammeter
back to normiebook now please
wouldn't magnets slow down or at least apply a force on the current?
Ohm's law:
change in electric potential = current * resistance
V = IR
rearrange to solve for current:
I= V/R
There is no power supply, therefore the change in potential is 0. Starts at 0 volts, and by the time the circuit completes itself there is still 0 volts.
What you have shown in the picture is the equivalent of touching the ends of a copper wire together.
Also, why don't you just fucking prove it to him in person? get a DMM and an old power strip, cut into it so that the wire is exposed, and measure the current. I'll bet you an African silver nickel that it will read 0.00 Amps

Somebody skipped intro to electrons 101
The trick here is to not converse with people without any sense. I doubt any evidence no matter how thorough or elegant will prevent him from being stupid.
um
Pick some differential equations of the circuits, put a starting current different than 0, and a resistance R>0, and prove that the current tends to 0 as time passes.
If you had a superconducting wire, then there would be current.
