i cant clear it further this is the best i can do sry for inconviniance.
A & B r the terminals
Q in the circuit diagram each resistor is of resistance 5 ohm . the points A and B r connected to terminals of a cell of emf 9 volt and internal resistance 2/3 ohm.
find heat produced in cell and the current in resistor directly btwn A and B..
wat i really want is how to break this circuit.

This was solved earlier oon the forum
think symmetry..
I dont remember the post
but what you can do is join symmetric points (ones that are symmetric about AB!)
After that it is very simple :)
