Question

1. Draw a circuit arrangement for studying the V-I characteristics of a p-n junction diode.
2. Show the shape of the characteristics of a diode.
3. Mention two information that you can get from these characteristics.

Answer 1

a.

b. 

c. Information from V to I characteristics:

Threshold Voltage: To conduct significantly, the diode requires a minimum forward voltage of 0.7 V for silicon and 0.3 V for germanium.

Breakdown Voltage: The reverse voltage at which the diode conducts strongly due to breakdown effects.
