I hear plenty of people saying that voltage is just the potential for current to flow through, ergo, not actual flow.
However, if the potential is higher, the current CAN be higher.
So my question is, if the voltage is, say, 120v, does that mean current can't be more than 120 amps(falling within a potential)? If no, please elaborate on what "potential" exactly means within a circuit.
Saying "the difference between two points" doesn't really form a good understanding in my brain.
Voltage = current / resistance. If a circuit has no resistors, does that imply that the current is equivalent to the voltage(no resistance)?
If I'm right, please explain how. If I'm wrong, fill us all in here with what exactly "potential" means, and how it affects current, is related to power/energy, etc.
EXTRA: What I can't seem to understand is how this all works together. Someone tells me voltage is current divided by resistance, but if there's no resistance the current can be enormously powerful with almost no voltage? What?! No one seems to make sense of this.
