Hey Jimmy! I did this question for you. Sorry for the poor quality. This should give you a better understanding on diodes in parallel and series. (and in opposite sides) :biggrin:

Well, not very. What topics are on unit 1 apart from electricity and particle physics?

Quantum is another chapter.

LOL I did a question on diodes for Jimmy20002013 and he is offline. HAHA

Hello Sophie. I am done for now lol. I just did a question on diode and posted my question with all the solutions for Jimmy. And now he is already offline. My attachment is up there. Anyway, whu? How was your maths exam the day before yesterday. I even posted the same question on the last post. :rolleyes:

Can you actually read the answers? I know it is a poor quality. Download the image and rotate it clockwise 90degrees. It is a really good question. It covers every rule for a diode.

Is that the hardest type of diode question that we could get ?

Yes definitely! btw Q is 10K Ohm

Why does X= 2.4V when the resistor is equal to 0.6V, could you quickly explain?

3V is a total voltage. since diode is in forward direction with a resistor, it will require 3-0.6=2.4V. (remember, a diode requires 0.6V to let the current through). If the diode was is series with resistor Q and in forward bias. diode will be 0.6V and resistor Q will be 2.4 instead. (it is opposite when diode is in parallel). Got it?
