Why are there two batteries connected in opposition?
Is this a school question or is it something you're making at home?
It's a scientific question that has blurred my mind for years. I need to know what what happens to the voltage and the lamp. (specially if we omit the burning of wire because of overheating possiblities) what will the voltages in such cases be?Why are there two batteries connected in opposition?

Yeah, but i want to know what happens if we make such a circuit ...4V=0V and many amps / warm battery.
That part of circuit is a little short of components!
Wow really? It's hard for me to accept that, cause according the kirchhoff 'slaw, at the upper part of the short circuit cable (cable in the middle) the electrons should flow in both left and right directions, and so i think the battery on the right should effect the lamp. ?Yes, battery on RHS contributes nothing to LHS due to the perfect short circuit![]()
My problem is not the resistance of the wires and they are ignorable for me (in real world it is less than 2 ohms for such a circuit if we do not assume the wires to be too long).'The resistance in wires are not considerable' - so even though they are small they are not zero. Is that what you assume? If this is indeed what you assume then draw the circuit out showing the resistances of these wires and then do the mesh current analysis.
There is another assumption you have made without knowing it - or maybe you know it but have not stated it and are ignoring it - something about each of the batteries ;-) Again, include this in your circuit diagram and then do the mesh current analysis.
I think you confusion arises from assumptions you are making or not aware of.
Is that centre line meant to be a connection or just an indication of the values to its left? Its poorly drawn out - any cross connections should show the small filled in blob as on the arrows.
