Experiment 4

i have observe the calucation by the ciruit and measuring the circuit by using voltimeter atfer that i use the formula to find the calucation to get the answer . then i measure the circut by using the voltimeter and it comes up the simlar number as the calucation.

12v was good on voltmeter. On muilitmeter measure each point from 10 to 15 you will see the zener diode controlling the voltage

Obtian a breadboard circuits finding all the volts drops from10 volts. by using the voltage supply thing. atfer that i use the voltmeter and disconnect the circuit and finding the volt drop it comes differnt number of volt 1 , volt 2 volt 3 volts 4volts.  atfer doing the 10volts supply i did the same thing for 15 volts supply.
