Hey guys,
I am looking for a point in the right direction for this problem.
The problem asks for the value of R for which the voltage across the resistor is 40mV. I assume I need to workout the current passing through the resistor. Since the resistor is in series with D1, which is in parallel with D2 the current should be divided. Once I have the current I can use Ohm's law to find R.
So I think what I need to find is the current passing through D1 and R.
Thanks
