If you add resistance to the circuit the bulb will shine with a fainter light ... the higher the resistance is the fainter it will shine
Edison failed many times - no one knows how many - to make a filament for a light bulb that would last a long time. He did not invent the light bulb - he was working on a BETTER light bulb that would last longer.
When a bulb is brown the whole bulb would be shaded brown and would be the same shade all over. When a bulb has blown or fused then firstly part of the bulb would be brown the rest of the bulb would be the original colour. Secondly the the internal element that looks like a spring will have broken and roll around inside the bulb.
No, copper wire cannot be used to make the filament of an electric bulb as copper wire has very low resistance. Therefore, the bulb will not glow if current is passed. It would also melt - the filament has to be white-hot to be any use!
Thomas Edison is quoted as saying "I did not fail, I found 2000 ways how to not make a light bulb." He did finally succeed in finding the one way to make a light bulb.

lower the voltage by using a different power source or by placeing a variable resistor in series with the light bulb.

Yes, it is true. The Sun would appear more than a thousand times fainter viewed from Pluto than it would as viewed from Earth.
fainter

it all depends on what the bulb is rated for4 extra volts on a 120 volt bulb is negligable4 extra volts on a 1 volt bulb will definitely pop the element, but I don't think it would explodeAnswerDepends on the bulb voltage, but it shouldn't explode. If it's a 6volt bulb or lower, it would burn out quickly.If it's a 12volt bulb or higher, it may have a shorter life, but it would be brighter.
