Voltmeters and Internal Resistance

Simple resistive circuit with voltmeter

Question: Does a voltmeter have any internal resistance, and if so, what, if any, affect does it have on voltage readings? Answer: Even if you have no electrical experience at all, I would hope that your answer to the first part of the question was, “yes.” Otherwise this would turn out to be an incredibly short …

I almost feel bad about the fact that I couldn’t even spell his name correctly until I was well into adulthood. You are probably thinking, “Sure, he had a bitchin’ robe, and for …

Complex Numbers and their Geometry

(Note: I lied. This will be my first “neural dump.” I began writing about Euler’s Formula, but felt what follows was worthy of its own post and a better foundation for what will follow when I tackle Euler.) Complex numbers arose from the fact that there is no solution for in the equation in , …

Why “Neural Dump?”

Leonhard Euler

I will soon be making the first post that I believe lives up to this site’s name, “Neural Dump.” The post will be an informal outline of the derivation of Euler’s Formula.  I consider this forthcoming post to be a “neural dump” since the audience I am primarily targeting is me. “Huh?” you ask. Well, …
