    Grounding, earths electrical field

    Hi guys, I have a question. So we all know that voltages seek a path to ground and we hold that the ground is considered 0voltage (electrically neutral) compared to say a power line or a lightning bolt. The hot wire or lightning will seek to balance their charges out and equalize. However, It...

    Amps higher than voltage possible?

    Hi guys, I have a question. From how I understand it Voltage and Amps are proportional to each other. e.i. 120V/8R= 15amp. In a short circuit you could have 120v and 120A (is it possible to pull higher amps off a powerline? assuming the circuit could handle the amps without burning up)...

    AC power generation and transformers

    Hi guys, I have a question. When electricity is generated how is it determined which side of the coal in the generator is the hot and which side is the neutral? Since AC fluctuates in polarity wouldn't both leads be essentially electrified? With that said, if the hot path was severed from the...

    How do energy plants safely measure power

    Hi, How does a given power plants measure the power being generated? Is it simply a mathematical estimate based upon materials, windings, speed, magnet strength ect? Or do they have a gigantic multimeter? haha

    Capacitors in parallel effects on frequency

    Hi all, I have a question on capacitors and signal chains. If I have a signal that goes through two capacitors in parallel of different values such as .01uf o and .005nf what would be the result? I understand that the lower .005nf capacitor would act as the path of least resistance to the...

    General electronic questions

    Hi guys, I have some questions that I am struggling to understand. Due to my situation I don't have much chance to experiment much and am stuck doing a lot of book learning. I understand how to solve for basic circuits. Here are my questions: 1.) House circuits have 120v 15A, however if I...
