circuit Q

JEE Advanced 2015 Discussion Forum › Electricity and magnetism questions › circuit Q

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 :)
