SECOND WEEKS OF WORKSHOP

DIODE

SECOND WEEK of workshop is fascinating when I manage to test diode, transistor and learn integrated circuit. We also are being informed by En. Ahmad Redzuan bin Mohd Hanapiah that we will be having our industrial visit in nearest time. Can’t wait for that moment to happens because it was my first time of industrial visit. Back to my instrument test, for the first class I focused on testing diode. Diode is functioning to allow currents flow in one direction while blocks currents oppose it

LED

PNP AND NPN TRANSISTOR

COMPONENT ANALYSER

I also had change to use component analyser to check for the internal value of diode. Using component analyser is much more easier compared to use multimeter BUT component analyser cannot be use to analyse bipolar capacitor because it will caused damaged to component analyser. Testing LED by physical inspection just by looking at it inner flag to determine which leg is cathode and anode. For LED to be light up it need to be connected to power source and resistor. Resistor? YES, resistor because if there is no resistor  to resist current flow LED might damaged.Component analyser again being used to test for transistor. Transistor can be differentiating into two which is PNP and NPN transistor. The last part of my test instrument is learn about intergrated circuit(IC). In single IC there may be about hundred of capacitor.

INTEGRATED CIRCUIT

This week class moved to a new level which is WORKSHOP. Its being taught not by Dr. Kamal but other lecturer. He is En. Ahmad Redzuan bin Mohd Hanapiah. He will be teach us for about 7 weeks and after that others lecturer will take over. Before i enter the class. I fell very excited because this class is more towards practical and me as boys really love when it comes to practical.  

FIRST class is on  11^th October, during this class  En. Ahmad Redzuan explain to us about what are we will be doing  throughout this 7 weeks. He tells us that during his class we will be deal with electronic  apparatus such as diode, capacitor and transistor. All this electronic apparatus  will be useful when we are making our own circuit board. En. Ahmad Redzuan also stress us about the 5S while we are deal with the apparatus.

SECOND class is on  13^th October, we had our instrument test during this class. We only manage to test resistor and capacitor only due to limit of time. Resistor function is to resist current. Without resistor, voltage cannot flow and the circuit is not completed. We test resistor by observing the colour  code. besides review to colour scheme, I also  used multimeter to check the actual value of the resistor.

multimeter that i had been used to measured all the apparatus

For capacitor, we actually test three type of capacitor which are disc ceramic capacitor, mica capacitor and radial capacitor. We measures the capacitors by using colour code, multimeter and by physical inspection.

We got three method to use because we need to test differend kind of capacitors. For mica type we used colour code, for ceramic capacitor we used physical inspection by looking at their code and compared its with the table provided while for radial capacitor we used multimeter. Actually, every electronic  apparatus can be measured with the correct mutimeter. Im very enjoyed during this workshop and can’t wait for the next meeting.
