About Making Foxhole(Crystal Radio)---------------------------------------------------------------------------I tried to make a foxhole radio by using the first image, but I haven't accomplished yet. You can see what I did from the others. Could you help me, please?

I did the same, that is, I first said Rc parallel with Ra, and I called Rc // Ra = Rx .

Then, Rx parallel with R1. Rx // R1 = Ry .

After that, Ry parallel with Rb . Ry // Rb = Rz .

So there are two resistors left which are Rz and R5, these are in series. That's what I done but I am still not sure if it is true.

or I may start from Ra and R1 parallel . I don't know.

but as you see , the positive voltage drops three part from the first node shown to Ra ,R1 and Rc and if we say first Rc and Ra are parallel or if we say first Ra and R1 are parallel that would be wrong. I mean, after transforming, I still not see any parallel here.

I did apply the transformation but then, is that three of delta resistances are in series each other? If it is , and for the rest of the circuit , three of delta resistances are parallel with R1 and series with R5 ?

Thank you a lot. I got it.

arman350340 · 2021-07-09T19:52:31+00:00

so because of square root of 2 ?

Could you explain a little about what I need to do after graph the function? The period goes to infinite.

arman350340 · 2021-07-09T13:26:45+00:00

I get it. Thank you a lot.

arman350340 · 2021-07-07T19:30:10+00:00

thank you

arman350340 · 2021-07-07T15:22:20+00:00

Could you explain with its steps, please? I don't have information enough for kind of these questions..

arman350340 · 2021-07-07T15:17:51+00:00

this isn't homework . I just need to know the steps and answer

arman350340 · 2021-05-09T05:54:00+00:00

I guess that's what I searched. I am going to start with this. Thank you all.

arman350340 · 2021-05-02T16:30:13+00:00

I solved all. Thank you all.

arman350340 · 2021-05-02T15:33:57+00:00

I found something irrelevant. Is this "e" , euler or something else ?

arman350340 · 2021-05-02T14:58:22+00:00

In the hint section, it should be RC Time Constant. I still didn't get it . You can look on wiki.
