    Hello and thank you for posting your question to Brainmass!

    The solution is attached below in two files. the files are identical in content, only differ in format. The first is in MS Word format, while the other is in Adobe pdf format. Therefore you can choose the format that is most suitable to you.

    The original circuit is:

    To simplify we note that R1 and R2 are in parallel, and they are both in series to R3
    Thus, we can collapse the three resistors into one equivalent resistor R0:

    In addition we denoted the currents and loops direction. The ...

    Solution Summary

    The expert uses Kirchhoffs law and Ohms law to determine the voltages and currents
