1. ### B Voltage vs charge?

If voltage is the difference in charge between 2 points, then why for a capacitor of a larger area or thinner dielectric cross section, do they say that it can store more charge given the same apppied voltage? Isnt voltage the difference in charge between 2 points? So if you can store more...
2. ### Single phase AC 3 wire neutral conductor shock potential?

I have a question with regard to split single phase (in United States) electricity. I understand that there are 2 hot legs each 180 degrees out of phase at +120v and -120v (240v between hot legs) going from transformer to breaker box and a center tapped neutral earth bonded wire at 0v with...
3. ### Help Moving from DC/AC to RF

I appreciate the generic answers, but im looking for something a bit more intuitive. Math is a language, like English, and i'm asking someone to answer my questions in English since its my first language and calculus is a distant second. Any experienced engineers who have transitioned from...
4. ### Help Moving from DC/AC to RF

I really hope i can get some answers to the questions that have been plaguing me for some time. I'm more conceptual, and math does not satisfy my curiosity so I was hoping the experts here could fill in some blanks: In making a jump from learning DC/low frequency AC to RF, i studied...
5. ### Antenna circuit theory help

Thanks for all the help I truly appreciate it!
6. ### Antenna circuit theory help

To rephrase my question: if the open ends of a dipole behave like a capacitor that passes high frequency then why isnt the same true for current that reaches a break in the TL. Why does it reflect in the TL but radiate at the load when physically theyre the same thing 2 conductors separated by...
7. ### Antenna circuit theory help

Yes...the thing is I fully understand what all the texts say but they do not accurately answer my question. You cant just say rf works that way as if it is magic. Rf is still alternating current from accelerating charges. Tl theory doesnt exactly pick up where basic theory left off it simply...
8. ### Antenna circuit theory help

I do not know that at all. Im confused if its not an open circuit at high frequency then why does an impedence mismatch which is essentially like a partially open circuit reflect the current? It seems like the description is double edged sword "its not an open circuit at high frequency so...
9. ### Antenna circuit theory help

antenna circuit theory help!! Im having trouble understanding vswr and current path in an antenna system. Example is the dipole...Ive read that the parasitic capacitance between the 2 wires forms the complete circuit but then I read about standing waves that reflect at the open circuit. My...
