Transistor (Test Instrument)

Continued of Monday's Lesson


                  I was impressed by the usage of the transistor... Never thought that transistor is a multi-function electronic component before until being asked by Mr.Redzuan.

      Function of transistor

• Act as a switch
• Amplifier
• Increase/decrease current, voltage, amplitude
• General purpose
• Audio driver
• Current mirror (produce branch current)
• Filter
• Deflector

Also learned that there are two types of bipolar junction transistor) : NPN and PNP

By using digital multimeter and component analyzer, we are able to know that the emitter, base and collector of a transistor. On Monday, we also taught that how to use the oscilloscope. It is just like a TV to show the wave form that were being set in value of voltage and current.

Everything seem like piece of cake for Mr.Redzuan but I wonder that whether I can do it well and remember all the things that had been taught in the practical test. Start to worry now.....
