Regardless of why the battery is providing any given current, the amount of heating for that current is always fixed. The current and the heating are directly proportional to each other because a given change in current always gives the same change in power output, so plotting power vs. current will give a straight line through the origin.

We start by making a circuit diagram, as in Figure (PageIndex{7}), showing the resistors, the current, (I), the battery and the battery arrow.Note that since this is a closed circuit with only one path, the current through the battery, (I), is the same as the current through the two resistors. Figure (PageIndex{7}): Two resistors connected in series with a …
How do electrical devices limit the current flow from a socket?
The load wire isn''t change resistance (much... heating up does increase resistance for most wires). Thus, if the current isn''t that high, the voltage can''t be high either. So even if you have a "1.5V battery," if you short it with a wire, the voltage between the ends will plummet, to some value which corresponds to this maximum amperage.
