Hey guys, I'm in need of some help.
First...
I know that the formula for a generator is V = N(turns) * A(m2) * B(tesla) * RPM
1. Is that valid for both AC and DC generators ?
2. Is the formula for a generator with only one magnet and one coil ?
If so, then adding more coils changes the RPM value ? In other words, are 2 coils regarded as a doubling of rotor frequency (RPM) ?
Secondly...
The zener diode produces a voltage drop, but how much current does it allow to pass in reverse ?
Is it like this :
15v - 5.6v = 9.4v, and the amperage is proportional to the passed voltage, or does the zener diode introduce more resistance and limits the current ?
Thank you
