Basically my friends and I can't decide what happens to a voltage source if it is dangling. Let me clarify that, the other end, the negative end of the voltage source is hanging in the air, not connected to ground (because it is still there if it's connected to ground). We'd like to think that it can be removed, just like what happens to a resistor/capacitor/inductor when it dangles because current does not pass through it because of the lack of a closed loop. But since it's an independent source, the case might be different.
For some reason I believe it should still be there since the other end is just dangling, therefore, no additional voltage is coming in, and that is very very similar to the case when a voltage source is connected to ground.
Buuut, by conservation of charge, whatever the source gave should come back to that same source, since you can't just supply an infinite amount of voltage to the circuit and not get it back. And KVL actually supports this.....
So does it still stay in the circuit or is it removed? And what's the difference between a dangling voltage source and a grounded voltage source, if any. Any help will be appreciated. Thanks. I think we resolved it but I want to make sure.
