Alexeia Posted May 21, 2013 Share Posted May 21, 2013 (edited) Hello, I attached a circuit diagram. I need to solve for the total resistance, current through I1, voltage over R6, and current through I5. I made an attempt by reducing the circuit to a simpler circuit. What confuses me is the current through I5, and whether R3 actually makes any difference to the total resistance of the circuit, because in my eyes it is as if it is bypassed by the wire carrying current I5. Help will be much appreciated. Thanks Diagram_Series_Parallel_Comb.pdf Edited May 21, 2013 by Alexeia Link to comment Share on other sites More sharing options...

Correct. There is a short circuit across R3. Link to comment Share on other sites More sharing options...
Alexeia Posted May 21, 2013 Author Share Posted May 21, 2013 So should I add the resistance of R3 when calculating the total resisitance or do I leave it out? Thanks Link to comment Share on other sites More sharing options...
EdEarl Posted May 21, 2013 Share Posted May 21, 2013 The short circuit essentially removes R3. Link to comment Share on other sites More sharing options...
