Question

Draw circuit arrangement for studying V-I characteristics of a p-n junction diode.

Hint:

In a typical V-I characteristic experiment, both forward and reverse biases are applied to observe how current behaves across the p-n junction.

Answer 1

The circuit setup for examining the V-I characteristics of a p-n junction diode includes:

(A) A variable DC power source.
(B) A p-n junction diode in series with a resistor.
(C) A voltmeter for measuring the diode's voltage.
(D) An ammeter for measuring the diode's current.

Forward and reverse voltages are applied to the diode by adjusting the power supply. The current is then recorded at various voltage levels to generate the V-I characteristics.
