Experiment No.4 - voltage drop

In this exercise we where given 1 resistor, 1 5v1 400mw zener diode and one 1N4007 diode. With these I made a circuit and measured voltage drop at given points.

Vs = 10 & 15v
R = 1k ohms




10 Volts 15 Volts
Volt drop v1 5.04v 5.16v
Volt drop v2 .74v .76v
volt drop v3 5.78v 5.93v
Volt drop v4 4.19v 9.02v
Caculated current A 4.19mA 9.02mA
With the Zener diode in reverse polarity it drops it rated voltage which is why V1 is around 5v. Because the other diode is in foward polarity it only uses up its rated .7v.

  1. You need to explain in more detail why this is happening also adding extra pages will make it easier to follow

  2. Hi Aero you need to update your blog adjusting it depending on my comments, also try not to get to far behind writing up your experiments
