Two opposing voltage source, of different current capacities?

Question

If two voltage source of the same value(20V) are wired in series and they both have different current capacities, could there be any current flow assuming the resistance(internal & circuit) are equal? I assume the voltages being the same and in series to oppose one another they would cancel out regardless of their current capacities?

Answer 1

Correct. No voltage drop across the resistor means that no current will flow through it. This is why cells of the same voltage can be placed in parallel with no bad effects.
