Thank you, duly noted. In #3 where/how do I mount the 10MΩ/1.8pF? In a small metal enclosure with two BNC's and then connect F-BNC directly to the scopes input without any cable in-between?
I thought I already proposed the "better configuration" by saying "Zs=50Ω/Zc=50Ω/Zl=1MΩ" where Zl is the...
When I have a signal source with a Zs=50Ω output impedance connected to a Zc=50Ω coax cable connected to the Zl=50Ω input impedance of my scope, In this case I understand that the power transferred to the load is 1/2 as per below illustration.
1. Does this Zs=50Ω/Zc=50Ω/Zl=50Ω configuration...
Well, that trick I didn't know, so thank you for that.
Then it's only fitting that I amend my statement to "it's [this post] generating VERY LITTLE of value"
So you are stating a personal opinion, and because of that opinion it's clear to you that measurements are wrong and therefore you can't be bothered to look at the facts even for all the money in the world.
It makes me think of this Leo Tolstoy quote:
“I know that most men, including those at...
Yes, but in this data series, the current is never zero, otherwise the calculating script throws a divide by zero warning, which it doesn't in this case. - so no zeros.
As I have said several times, and as it can be seen in the trace, before the pulse - both current and voltage are zero. And...
Yes that's how it's calculated.
Yes, I agree in the case of singular points, but 6.7e10 as in the plot is still finite.
And what if both U(t) AND I(t), as the case is here, are not constants in time?
As a service for the persons reading this post, I made the following calculations:
I took the first full pulse from the data file (SDS00001.CSV attached in previous thread) and it looks like this
Then I inverted the current by multiplying it with -1 and the result looks like this
Note that...
I agree the mathematics is definitely not trivial, that's why it even more impressive that Nick Lucid (the video channel owner) still manages to covey the essence of such complex math only by the use of proper pedagogy. I know it is not in any way complete, but it is a extremely good starting...
I had to make a new measurement to record the full pulse and a bit more. The only change I have made is the nominal value of "R" I lowered it from 1.1M to 883K which resulted in higher voltage and longer pulse duration.
For arguments sake, even if I didn't know how to properly use the CT, as...
Hi friends
It seems to me that fundamental electric theory is no longer taught in school, which is a shame as it results in everyone having their own intuition and interpretation about it, leading to silly and time wasting discussions which everyone would be better without.
In an attempt to...
I don't appreciate your irony. Where do you find excess energy? The negative current goes back to the source's power supply, the power supply performs work (Work as in W = F * d * cosθ) on it at a energy cost equal to the amount released by the Resistor.
Energy in = Energy out
Which I...
In stead of expressing your personal distrust maybe you should start by posing me a question. Obviously the traces don't start "out of nothing" I just chose to start at that particular point when load is applied, prior to that point both traces are 0V complete flatliners. As I tried to explain...
I would say at least one, but I am willing to entertain the possibility of two.
I vote in favor of that suggestion, I already spent $1.000 on the CT, if the CT is yielding incorrect results I can at least claim my money back. If anyone knows anyone reputable that is willing to validate the...
Hi Klaus
The simple and only reason I talk about R as an ohmic load is:
I did not say it behaved like an ohmic load, because according to the measurements it definitely doesn't, which is the only reason I'm posting this. I was initially confused and in doubt on how to handle this and make a...
Hi Klaus.
First let me make my intentions very clear:
What I have recorded is NOT the desired result, so I need to establish a baseline to move away from the current result. I need help/suggestions to calculate and establish such a baseline.
I have recorded what I have recorded, if I made...
