New to the forum :)
We were (trying to) discussing this at work the other day. Consider a simple battery powered circuit, with a resistor and an LED. With a battery, current is "chemically produced" in the battery and flows from the positive to the negative pole, passing through the LED (limited by the resistor) and "returning" (?) to the battery's negative pole. This is a correct summary?
But what if we disconnect the battery's negative pole, and connect the LED's cathode to "ground/earth" instead? Like, a big ol' iron pole into the ground. Theoretically, this should make no difference in terms of the curcuit, but would current still flow from the battery? If so, would we somehow destroy the battery?Joakim
