Experiment 8






Firsrty Vce through the experiment the Vce numbers changes becuase all differnt type of resistor .soon i chnaged the resisoter differnt numbers come differnt resister but not everything the same.The reason why beascause i test the voltmeter in diffent pisiton from the the red lead hits on the tranisitor on the Base and the other leads go on the emiitt


Firsty Vbe through the experiment the numbers are very simlar to 0.6 to 0.7mA to all the resistors.



Firsty Ib through the expiermnet the Ib numbers are totally differnt to the all type of resistor that i used. the reason why i disconnect the resistor and using the multer on the resistor and other lead goes on the lead and it comes up the numbers and it showing it how mch mA . but not all the same number in all differnt resistor that i used.



Firsty Ic through the experiment the caulation are differnt than other resistor i used the reason why well it simlar i did to the Ib well i disconnet the main resistor and putin the lead on the resistor and other lead goes on the Red led on the anode and the reasult came out.
Atfer that i started to make the graphic of the caulation for the Ic and Ib to see how mch cut off and saturated and also the load line so i used the IC and IB to match the lines the follows the way and match and put the number in the right order like from the smallers to the biggers

Experiment 6

Testing tranisitor
the tranisitor letter goes to which muiltmeter leads like red or black. whatever is choosen need to be used throughout the circuits from them .
the base is commond betweeen emitter and collector. the middle leg is the base bt nt alway the middle one.
i used the black lead on the base it wil be the PNP
with the red lead on the base wil be NPN

Experiment 5









I have done the capacitor charging cicuit with the difffernts of resitor and cacpacitor and it calcated all the differnts number.atfer working out the resitor and capacitor i use the oscilloscope to observed the time of ms. the answer came bit simlar to the calcaution of the resitor and cacpacitor

Experiment 3

The experiment showed how the zener kept the voltage at about the same as when you increased the supply voltage. . The zeneer into revesve bias. The cathode side showed how to select revrese
