I just wanted some feedback on the basic theory section.... I tried to make it understandable while showing the math for those that are really interested in figuring out amplifier output for a given speaker configuration.
I look back at the notes and it seems like a pile of calculations.... are they too much???
Should I simplify further??
At this point the next things to get into are capacitors and inductors (coils) but these are somewhat more complex and I'm not too sure everyone will understand how they work.
Perhaps I will quickly jump into some transistor theory as well as it's very interesting and easier to understand than something like a capacitor which involves quite a bit of physics and EM wave theory.
A capacitor uses electric fields to store energy while inductors use magnetic fields to store energy..... and they work off something called imaginary power
and no... I'm not kidding.... it's quite complex.... you have to get into evil math called Laplace and Fourier transforms to calculate things.Some capacitor and inductor functions can be calculated in equations but neither device uses power.... they store power and return power (in theory)
So to simplify things.... lets say I push 50V and 1 amp into a capacitor for 10 seconds..... then if I reverse it and suck 1 amp at 50V out of the capacitor it's "charge" will last 10 seconds.
So the net power is exactly zero..... power in = power out
This isn't really true because the capacitor has some internal resistance... but certain types of capacitors are very close to perfect energy storage devices.
As usual.... I'm getting off topic......
Any comments ( constructive or destructive ) are appreciated.
If you see any mistakes please let me know.... I write the post.... go over it once or twice very quickly and that's it..... so it's easy for me to miss stuff.
If there are any questions this is the time to ask them.
