Homework Statement
For the circuit shown in Fig. 4.26 both diodes are identical. Find the value of R for which V=80mV
Homework Equations
I'm not quite sure what equation to use here. If you look at the wiki page on diodes http://en.wikipedia.org/wiki/Diode
it might be Shockleys current equation
The Attempt at a Solution
My thought on how to approach this problem is find the current that comes out of the diode and then use that current in a voltage divider using 80mV to find a value of R. Though I have no clue what is coming out of the diode. Though I know 5mA is going to each diode.[URL]http://img218.imageshack.us/i/fig426.png/[/URL]
