    Study Notes

    Experiment Overview

    • This experiment aims to study the characteristics of a Zener diode in reverse bias and determine its breakdown voltage.
    • The experiment uses a DC power supply, milliameter, voltmeter, connecting wires, and a Zener diode.

    Zener Diode Function

    • The Zener diode operates in reverse bias and is designed to regulate voltage across a load when input voltage or load current fluctuates.
    • The Zener diode, along with a resistor (RS), is connected in parallel to the load (RL) to form a Zener regulator circuit.
    • The breakdown voltage of the Zener diode (Vz) determines the output voltage across the load.

    Experimental Setup

    • The experimental setup has a variable DC power supply, a resistor, a Zener diode, and a load resistor.
    • The input voltage (Vi) is varied, and the current through the Zener diode (Iz) and voltage across it (Vz) are measured.

    Experimental Results and Graph

    • The observation table summarizes the collected data showing input voltage (Vi), current through the Zener (Iz), and voltage across the Zener (Vz).
    • The graph represents the relationship between Vz and Iz, plotted as a curve with negative X and Y axes.
    • The graph exhibits a steep slope initially, followed by a plateau after the breakdown voltage.
    • The breakdown voltage for this particular Zener diode is estimated at approximately 6.78 volts.

    Interpretation

    • The graph demonstrates that as the input voltage increases beyond the breakdown voltage, the current increases significantly, but the output voltage remains relatively constant.
    • This behavior highlights the voltage regulation capability of the Zener diode.
    • The Zener diode effectively stabilizes the output voltage against variations in input voltage.
