Transistor Characteristics Apparatus Manufacturer,Supplier and Exporter in India
Product Code : SCL-EAE-11329
The apparatus is arranged around an NPN transistor connected in common-emitter configuration, with the emitter serving as the common reference for the input and output circuits. Students can vary the base-emitter and collector-emitter conditions and record the corresponding base and collector currents.
The recorded observations support graphical analysis of transistor behaviour in cutoff, active and saturation regions. The common-emitter configuration is widely used for studying transistor amplification because changes in base current control the collector current. Exact meter ranges, power-supply outputs, transistor rating and panel construction must be confirmed before ordering.
Key Features
Confirmed NPN configuration: Demonstrates an NPN bipolar junction transistor in common-emitter connection.
Input-characteristic study: Supports plotting base current against base-emitter voltage at a selected collector-emitter voltage.
Output-characteristic study: Enables collector current to be plotted against collector-emitter voltage at selected base-current values.
Operating-region analysis: Helps learners distinguish cutoff, active and saturation behaviour.
Current-gain calculation: Recorded base and collector currents can be used to estimate common-emitter current gain.
Hands-on measurement: Converts transistor equations and circuit symbols into observable laboratory results.
Structured practical learning: Suitable for instructor demonstrations and repeatable student experiments.

How to Use the Common Emitter NPN Transistor Characteristics Apparatus
Identify the transistor base, collector and emitter terminals.
Confirm the approved transistor, meter and supply ratings.
Set all variable controls to their minimum positions.
Keep the apparatus switched off while making connections.
For the input curve, maintain the specified collector-emitter voltage.
Increase the base-emitter voltage gradually and record the base current.
For the output curve, select a base-current value and vary the collector-emitter voltage.
Record the corresponding collector-current readings.
Repeat the procedure for additional base-current settings and plot the curves.
Return all controls to minimum before switching off.
Safety note: Use appropriate current limiting and do not exceed the confirmed base current, collector current, collector-emitter voltage or transistor power-dissipation rating.
