Question

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

Hint:

A simple circuit with a variable DC power supply, a series resistor, and a diode is used to plot the V-I characteristics.

Answer 1

The circuit for studying the V-I characteristics of a p-n junction diode typically includes:
- A variable DC power supply to provide different values of voltage \( V \),
- A p-n junction diode,
- A series resistor to limit the current through the diode, and
- A voltmeter and ammeter to measure the voltage across and the current through the diode, respectively.
Here is a simple diagram: \[ \begin{array}{c} \text{DC Power Supply} \quad \longrightarrow \quad \text{Series Resistor} \quad \longrightarrow \quad \text{P-N Junction Diode} \quad \longrightarrow \quad \text{Ammeter} \quad \longrightarrow \quad \text{Voltmeter} \end{array} \] The current and voltage are varied, and the corresponding V-I characteristics are plotted.
