http://www.electronics-tutorials.ws/dccircuits/dcp_10.html on this link the theory that is to be used is given.. using it, consider the loop containing resistances 2,3,4 ohms..call it loop1. it is a delta network which can be converted to an equivalent star network with resistances 8/9, 6/9 and 12/9. now the circuit is simplified to a series connection of 6/9 ohm resistor, to a parallel connection of (8/9,5 in series) and (12/9, 7 in series). now that is easy to calculate and the answer comeas out to be 4.1171875 exactly.

Whenever we have to find resistance of a circuit, mark each joint with a letter, then combine those letters in such a way that it becomes easier to solve, such diagrams are called equivelant diagrams. After you make an equivelant circuit for the above, you get the type of the question. In this case it is unbalanced wheat stone bridge, and then you calculate Aviral Chawla · 1 year, 12 months ago
