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.
