The currentvoltage relationship of a diode is given by the f

The current?voltage relationship of a diode is given by the following graphic:

Suppose now the diode is connected in series with a resistor R (figure below) and is fully conducting (forward bias region). Calculate the approximate value of the current in the circuit. Can you plot the operational point on the above graphic?

Solution

From the graph diode forward voltage drop is 0.7v.

By applying kvl :-2+0.7+I*1=0

I=1.3amps

Diode operating point is (0.7,1300m)
