I have posted a link to a falstad circuit which I made, could someone please explain to me why the current in the third voltage source flows backward with -70 mA?
And if possible run through the circuit analysis steps you would take to work out the voltage and currents in the circuit?

Thank you.

In normal condition we connect the load across voltage source terminal (we discharge a battery).
And this load current is drawn from the voltage source. And we treat this current as a positive direction. But when current is flow in opposite direction (we charge a battery), we give this current a minus sign.

Maybe you first show as circuit analysis steps?
