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. · 2 years, 2 months ago
