Lab 8 The Diode Objective: Measure the current-voltage curve of a silicon diode.

Reverse current

  1. Construct the circuit below using a DC power supply, a diode.
  2. attach an Oscilloscope set to 1M[math]\Omega[/math] input impedence as shown in the circuit diagram. The oscilloscope will serve as a Resistor to measure the voltage across the diode and calculate the current.
  3. Measure the diode reverse current [math]I_r[/math] as a function of the DC supply voltage.

Forward Current
