Transistor audio amplifier with power supply and different loads Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12268
Indian Lab Suppliers supplies the Transistor audio amplifier with power supply and different loads (Product ID: 12268) as part of its electronics engineering lab equipment range. It is a single-stage common-emitter audio amplifier that can be run with a resistive, an inductive or a transformer load.
Quick Answer
The board holds an NPN transistor stage, an audio output transformer and a 12 V DC, 100 mA IC-regulated supply wired internally. With each of the three loads students measure voltage gain, plot the frequency response, and find the input and output impedance of the RC-coupled CE stage, then compare how the load changes gain and bandwidth. A decade AF generator, AC millivoltmeter, decade resistance box and 20 MHz CRO are required and not included.
