Pulsed DC Transformer with Embedded Magnets

[quarktoo]

See post above - huge brain lock on my part - I was wrong and TinsleKoala was right. Sorry is a punk and I am sorry TinselKoala pissed me off.

I actually just went out and hooked a dc motor to a extech power supply with a resistor in series and when the motor sped up and I realized the amp meter just shorted the across the resistor I went... oh.. shit!

It happens... Pops is getting old.

@TK 1952?? You are very well preserved [your telescope vid] must be the good life!

Well, Quark2, it's good of you to admit that you are wrong. Now, let's see where else you are wrong. I inferred from your earlier posts on this topic that you did not have an oscilloscope, because I thought SURELY anyone who has a scope SURELY would know 1) that it measures VOLTAGE vs. TIME and VOLTAGE ONLY, and 2) how to calculate the values of parallel resistors, and 3) how to use the VOLTAGE DROP across a resistive element to determine current via Ohm's Law. Since you were wrong about each of those things, yes, I INFERRED that you don't own a scope. Sorry (Canadian Style).

Now.... I have cut-and-pasted quotes from you in my above posts. Please indicate just where I have misquoted you, and I will apologise and correct the misquote.

And, while you are at it, please hit the topics that we haven't yet covered: the statement about the phase relationship between voltage and current in a purely resistive element, for example. What about that?

Now, nobody was calling names or making personal insults until YOU started it, quark2. And yet.... you were entirely wrong about what you were claiming. That is what pisses me off more than anything else. Rather than stick to the technical discussion, providing citations and proofs for what you claim, as I do, you start getting snotty and insulting. Which of course liberates me to do the same.

I took the time today to make a video illustrating the computation of parallel resistors and the method of obtaining current from monitoring the voltage drop across them, confirmed with a non-contact current probe and an expensive oscilloscope. Two simultaneous methods in agreement: the non-contact probe and the voltage drop give nearly identical readings (on a 60 Hz sine wave input signal, lighting up an LED for load), and a third method, a series connection through a Simpson analog milliampmeter, not so much.
I'll post it to my YT account in a couple of hours or so, after I get home from the lab. But since Q2 has admitted some of his errors it's not so important, I guess.

(Incidentally, Professor, Lawrence, and Rosemary, the LeCroy AP015 current probe I am using is rated from DC to 50 MHz; that should be a wide enough bandwidth to test a 20 kHz blocking oscillator, I should think....)

Note my scope on the right hand side. Are you a short fat guy?
