A
Diode Problem - (3.1)
In this circuit, you want to light the LED by passing 1ma of current
through
the LED. The supply voltage, Vin, is 5v.

Your job is to do the following:
- Determine
the value of the resistance, R, (in ohms) that will give 1 ma through
the
diode taking the threshold voltage of the LED into account.
