The relationship of wire diameter and electricity produced

[Troymoore4]

im doing some personal research into building my own generator. i am looking for info on how wire diameter affects the power produced by the generator. specificaly: what AWG of wire is best for coils that are being used to generate as clost to the statdard killowatt/hour as possible.

that doesn't really make sense ... there is no standard kilowatt hrs

generators would normally be designed to produce a given voltage and capable of a maximum current capability

Wire size is most associated with maximum current.

But there is the problem of physically winding a coil. The thicker the wire, the larger the radius to the outermost winding. Equivalently, within the same volume and form factor for a coil, the thicker the wire the smaller the number of turns. It is not easy to calculate performance with alternate designs.

I have seen online calculators that aid with DIY transformer design. Perhaps there is something similar for generators. Try searching for "online generator design calculator"

The design of a DC generator will be very similar to a DC motor. Do you plan a DC generator or an AC alternator?
Here is an AWG wire table that gives diameter, ampacity etc; https://en.wikipedia.org/wiki/American_wire_gauge

It was some decades ago already, but as I recall in this regard generators works ~ the same way as transformers. The core parameters together with the frequency determines the maximal power: the maximal power and the available cross section for wire together fits with the wire thickness and turns in the coil.

So there is no real 'standard' or 'optimal': within the available cross section you can more or less freely trade between thick wire/high current/low voltage to thin wire/low current/high voltage.

You should think around the parameter 'Turns per Square Inch of Insulated Wire'.
