After this experiment, the concept behind the working of a transistor should be fairly clear as well as its application as an amplifier. Background Information Transistors are tiny electronic switches. They are the main components of microprocessors, which are essential to many of the products we use every day such as TVs, cars, radios, telephones, computers and many home appliances.
Transistors are also essential parts of amplifier circuits and devices.
Materials Used One transistor, two resistors of 2k W , 5.1k W and 200 W value, 1k W variable resistor on the trainer board, multimeters, function generator, oscilloscope, two 0.1 m F capacitors, and banana to alligators wires. Procedure Transistors as Amplifier A circuit based on the figure 1 was setup. Also the function generator was used to provide the input voltage V in . A sinusoidal input of frequency 10 KHz was used and the amplitude was set to the smallest value. Then, using the oscilloscope, the amplitude of the input and output measured.
