Let's imagine there is a circuit that contains two identical cells connected wrong way round i.e. in reverse, and nothing else.
I know that normally one will therefore say that the emf of the two cells cancel and hence by Ohm's law no current flows- assuming that there is some resistance in the wires.
However, now let the situation be ideal such that the wires in the circuit have 0 resistance and the cells themselves also have 0 internal resistance. Therefore, there is no resistance anywhere in the circuit.
Now, were I to apply Ohm's law, I=V/R, then as R tends to 0, I will tend to infinity. Does this therefore mean that even though the p.d. is 0 in the circuit, the current is however infinite?
Is this the situation for a 0 resistance circuit containing only a cell and an inductor- with the cell's emf and the inductor's back emf?
Thank you for answering the question.
