Hi. Actually, this is embarrassing, but my question is simply an algebra question. I know the equation and I know the answer, but I can't remember how to GET the answer. Can someone please walk me through this very simple algebra issue?
Equivalent resistance in a circuit = 26 ohms
R1 and R2 are parallel resistors; R1 = 55 ohms
R1 and R2 are in series with R3, which = 12 ohms.
The equation, as given by my professor, is:
26 = 12 + [1 / (1/55) + (1/R2)]
(Answer = 19 ohms)
I just can remember how to solve for that R.
