The only solution stuck in my head goes through finding the resistance from the slope of the curves and using it somehow in the solution, however, I can't figure out what voltage do I use for X and Y? (The current will obviously be the same for both.)
How does one approach exercises of this type?
Two resistors, X and Y, have I–V characteristics given by the graph.
The resistors X and Y are connected in series to the same cell. Estimate the total current leaving the cell in this circuit.
P. S. The resistors X and Y connected to a cell of emf 1.5 V
