What happens if my circuit draws more current than my source is able to supply? For example, if I have a source that can supply 1 V and 1 A and I attach it to a resistor that is 0.5 ohms, the circuit will try to draw 2 A but my source is only rated to supply 1 A. What happens here?
Would the source supply the maximum rated current of 1 A and only be able to output 0.5V ? Or would the source begin to overheat?
How would this be different from connecting the 1 V 1 A source to a short circuit? In this case, I am trying to draw near infinite current but I can only supply 2 A.
