It is indeed a very interesting approach. And now I can try some things as n is getting higher. Thank you again sir.

Hey there community, I have a question on an exercise. Actually it is a general question based on it. Here is the exercise: We throw 3 dice. If we know that the sum of these 3 is 10, then what is the probability of at least one of them being 3? Well now, this exercise is very simple. I mean I...

Hello there guys. As the title says, for quite some time now I've been looking for some extra sources of information. I am working with the book "introduction to electrodynamics" by David J Griffiths and even though it is good, I am thinking that it would be better to enrich my studies in this...

Ah, I see. Now I can continue based on your remarks further. Thank you very much sir.

Hey guys, what's up? I have some questions regarding the Poisson Process. I checked some threads, but not all, so forgive me if these questions have been answered before. 1)Lets say I am given some some tables or/and graphs or generally speaking some data and I am asked to find out if the...

I see yes.Thit is surely a relief.Your help is truly appreciated!

Hello there.I have a question about how to find the frequency cutoff in a breadboard with oscilloscope,multimeter etc Ok the circuit it simple.Ac voltage source in series with a resistor,which is in series with a capacitor.I am given that in the frequence cutoff the voltage of the capacitor is...

So as the title says i need to learn some things about the function point Q of a transistor/amplifier. It is written in books that we need it steady,we need it not affected by β etc,it says how to find it etc But i don't know the meaning of this.What does the Q point represent?It refers to the...

Ok so there is Base current.So i found it by using Ibq=IEq/(1+β).And it is around 0.0099mA.Vceq as found in the pdf is 8.6V.Was this the whole exercise?I mean i just used the DC equivalent.Am i missing something?Ibq isn't the dc base current & vceq the dc voltage?Won't they be found by using...

Of course it helped sir.First thing in the morning,tomorrow,i will retry.So for now,have a good night.

Homework Statement In the following common base circuit,β=100.If Vcc=15V, VEE=4V,RE=3.3KΩ, Rc=7,1KΩ find the Ibq and Vceq(they are related to the dc values of the Q point) Homework EquationsThe Attempt at a Solution Well ah...i mainly want to ask some things.However knowing that i must...

Yes you are right,they seem harsh but i don't get easily discouraged.I downloaded LTspice and i will work with it.Moreover,i will keep posting more exercises and questions as i move.So for now,goodnight :)

Well thanks you to you sir and to mrGneill ofc, many questions were answered and now i can see the problem a lot better than before.I am grateful.

Ah for these as well huh?Well it is a lot clearer now. I believe i forgot the 5 DC voltage source.Wouldn't it be 5-10=-5 volt.Meaning C charges to a voltage of the peak voltage on its left side minus the 5V battery voltage on its right What is the peak voltage?It is 20 now.Or peak is 25 and it...

Still confused.Let me ask you some more. 1)I read that if we have in a circuit both DC and AC voltage sources,then we analyze them separately.For DC analysis i open all the capacitors.For AC analysis i substitute all DC voltage sources with AC grounds and i substitute the...
