I see... Now, how about using an alternator connected to some kind of water wheel? If I were to rectify the current into DC to charge a battery, then would that be any better?
Let's say there was a 12V, 105 A, 5000 RPM alternator. Would that make this any easier dealing with AC current?
Ok, I'm new to electronics and have some pretty simple questions that I can't seem to find answers to elsewhere. Let's say I have a DC motor that I want to use as a generator with the following specifications:
130 VDC
17 A
5950 RPM
I know that in order to generate 130 Volts, that would...
Here is the problem:
Given that electric potential is given as a function of x and y: V(x,y)=20x4 + 60y3
What is Ex at (2,1)?
I have tried using E=-DV/DV, but I keep getting confused on how to derive this as it's been a while since I took calculus. I am also unsure of how to plug in the...
