Solving Resistors in a Circuit: Working Backwards

[csmith23]

Problem: I have found the total current running through the entire circuit. My problem is now I am trying to work backwards to determine the current through a certain resistor. I know when dealing with basic capacitors, voltage in parallel is the same, and charge in series is the same. Does the same apply to working with a circuit that only involves resistors?

Thanks.

I believe I found the correct way to do this. It would have helped if I was approaching the problem a different way.

Okay ran into another circuits issue. We have to compute the voltage of the entire circuit. I have set up my systems of equations. However for "v" I need a value. I use the rref feature in the calculator to determine currents. I am not exactly sure how to go about solving this the way I have been taught.

Welcome to MHB, csmith23! Could you please post a picture of the problem that's not hidden behind a password? Or type up the problem statement?

Thanks!

The current in resistance i6 is 1.4A. The resistances R1 = R2 = R3 = 2.00 ohms. R4 = 16 ohms, R5 8.00 ohms and R6 = 4.00 ohms. what is the ideal voltage of the battery.

Hopefully this link works.

I think this is the same as http://mathhelpboards.com/other-advanced-topics-20/mesh-currents-emfs-resistances-10968.html.
