Engineering Series/Parallel Resistor Circuits (Diagonal Resistor)

AI Thread Summary
The discussion centers on solving a circuit problem involving resistors, particularly focusing on a diagonal 6 Ohm resistor and its configuration. The initial confusion arises from determining how the 6 Ohm resistor connects with others in the circuit. After analyzing the circuit and isolating resistors, one participant successfully calculated the total resistance to be 5 Ohms, confirming their approach was correct. Redrawing the circuit and simplifying it step-by-step proved beneficial in reaching the solution. Ultimately, the correct total resistance for the configuration was established as 5 Ohms.

Homework Equations


Kirchhoff's Current and Voltage Laws, Resistors in parallel and in Series.

The Attempt at a Solution


The main thing confusing me is the diagonal 6 Ohms, not too sure what it is parallel too and how to add them, however the answer i did achieve was adding the 10, 6 and 3 in parallel and finally adding the 8 which gives an answer of 9.6 recurring Ohms, however within my lecture, a person answered the problem as 5 ohms and the lecturer said he was correct, this is mainly just confusion on my part.

For simple circuits such as this one, it helps to isolate a couple of resistors at a time, rather than trying to figure out how all of the resistors connect with one another at once.

For this circuit, first look at R3 and R4. How are these two resistors connected with respect to one another?

It also helps to redraw the circuit, keeping in mind to preserve the connections of the resistors with one another, as you progress.

Thanks a lot, just found the answer to be 5,

what I did was configure the circuit like so http://i.gyazo.com/6d2a8e8d117cd4be1ea9d53fde71e8fb.png

calculate the resisatnce in parallel to reduce the circuit basically to http://i.gyazo.com/e8a352411f710659b0df79bb98191096.png

which is also the same as http://i.gyazo.com/d27b9e7cc22cf9c63e836dcfa03d8ebe.png

which equals a total of 5 ohms, was this deduction the correct way to approach?
