Does anyone have a clear understanding on the relationship between the filament size of a lightbulb and the wattage? I was under the impression that resistance causes the filament to heat up and glow, so the more resistance the brighter the light bulb. A filament with more resistance, then, would have to be smaller. However I have read that a larger filament causes a bulb to grow brighter. Is this true, and why?
Thanks
