Hi
I need circuit diagrams for studying P-N junction & Zener Diode under forward and reverse bias. I know they are available on Google, but I had a few questions, and if I understand the answers, I won't need circuit diagrams.
1. a) Some circuit diagrams have a rheostat connected in series with the diode and some have it in parallel. What is the difference ? (b) In parallel type circuits, is the logic behind placing a rheostat same as in series (In case you short-circuit some components, current would be limited) ?
2. If you want to study a diode under reverse bias, what changes would be necessary ? Can you just flip the diode, and the ammeter, and the voltmeter ?
3. Will the same diagram work for a zener diode, both under forward and reverse bias, or do I need a different diagram for that ?
4. In our physics lab, we have a box type of thing. Everything is located inside the box, and we're provided with sockets at the end of each component. We are just supposed to join the wires correctly.
What confuses me is that there are two different diodes for forward and reverse bias in that box. So if you need to study forward bias, you use diode 1, and for reverse bias, diode 2. What is the logic behind this ? Why can't one just reverse the diode 1 to use it in reverse bias ?
Thanks for answering.
