EXPERIMENT 3


ZENER DIODES: In this experiment I placed a zener diode in reverse bias in a parallel curcuit with two 100ohm resistors. The zener diode was a 5v1 400mW. Tested twice, when Vs= 10v & 15v. I found when testing the voltage drop with the different Vs values the voltage drop was the around the same. This is because the voltage drop across a zener diode in reversa bias will always be the same no matter how much voltage is supplied because the voltage pressure required to push through in reverse bias is 5volts. When I tested it in forward bias i got a voltage drop of .86V. This reading tells us that the voltge pressure used to push through the zener to make it work is around .6V-.7V

  2. Good start a pic of the circuit and what could we use this circuit for and a more in depth explanation of why Zd did not change. you need to show your calculations as well
