PN Junction Diode Characteristics Apparatus – 2 Meter
Product Code : SCL-EAE-11362
The apparatus provides an organised platform for applying a controlled electrical input to a PN junction diode. Its two-meter configuration allows learners to observe voltage and current during the experiment. Exact meter ranges and measurement units must be ed against the final technical datasheet.
Students can take a sequence of readings, record the results in an observation table and plot current against voltage. This hands-on method connects semiconductor theory with measurable circuit behaviour and supports both individual practical work and teacher-led demonstrations.
Key Features
Two-meter configuration: Supports simultaneous observation of the electrical quantities required for diode-characteristic experiments.
Forward-bias study: Demonstrates how diode current changes as forward voltage increases.
Reverse-bias study: Allows reverse-current behaviour to be examined within the verified operating limits.
V-I curve plotting: Produces paired readings for preparing forward- and reverse-characteristic graphs.
Accessible experiment layout: Keeps terminals, controls and measuring sections organised for supervised use.
Direct analog observation: Helps students understand scale reading, pointer movement and measurement changes.
Classroom-ready learning: Supports semiconductor physics, basic electronics and STEM demonstrations.

How to Use the PN Junction Diode Characteristics Apparatus – 2 Meter
Place the apparatus on a stable, dry laboratory bench.
Identify the diode section, meters, terminals and adjustment controls.
Set all adjustable controls to their minimum positions.
Connect the diode in forward bias using the supplied circuit diagram.
Switch on the apparatus and increase the input gradually.
Record each corresponding voltage and current reading.
Return the controls to minimum and switch off the power.
Reconnect the diode for reverse-bias measurement.
Record readings within the specified limits and plot both V-I curves.
Safety note: Change connections only when the apparatus is switched off. Do not exceed the ed voltage, current or diode ratings. Qualified teacher or laboratory supervision is required.

Frequently Asked Questions
What is a two-meter PN junction diode apparatus used for?
It is used to observe the voltage and current of a PN junction diode and plot its forward- and reverse-bias V-I characteristics.
Why does the apparatus have two meters?
The two-meter arrangement supports observation of the electrical quantities needed for the experiment. The exact function and range of each meter should be ed before ordering.
What happens when a PN junction diode is forward biased?
Forward bias reduces the junction barrier. Diode current then increases significantly after the device enters its conduction region.
What happens when the diode is reverse biased?
A small reverse current normally flows within the safe operating region. The apparatus must not be operated beyond its ed reverse-voltage limit.
Can students plot a diode V-I curve with this apparatus?
Yes. Students record corresponding voltage and current readings and plot current on the vertical axis against voltage on the horizontal axis.
Are patch cords and instructions included?
The supplied accessories have not been verified. the patch cords, experiment manual and complete kit contents in the final quotation.
