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 arrangement for studying the V-I characteristics of a p-n junction diode consists of the following components:

(A) A DC power supply to provide variable voltage.
(B) A p-n junction diode connected in series with a resistor.
(C) A voltmeter to measure the voltage across the diode.
(D) An ammeter to measure the current flowing through the diode.

The power supply is adjusted to apply forward and reverse voltages to the diode, and the current is measured for different values of voltage to plot the V-I characteristics.
