Question 17.1: Determine the current flowing in the following circuit and t......

To determine the current, we first draw the diode characteristic with an extended voltage axis, then superimpose the load line. The load line is defined by the point on the voltage axis where V is equal to the applied voltage (5 V) and the point on the current axis where I = E/R = 5  V/1  kΩ = 5  mA .

The point of intersection of the two lines shows the current in the circuit (4.25 mA) and the voltage across the diode (0.75 V).
