Edisons most important inventions are the bulb, the pornograph and the improvement to the photograph camera.
Take two pieces of wire, one battery and one light bulb. Battery and light bulb should be the same voltage. Attach one end of one piece of wire to one pole of the battery (Soldering it would be best). Attach one end of the other piece of wire to the other pole of the battery and the other end of the wire to side conductor of the light bulb. You are done. To test the conductivity of something you simply touch the center conductor of the light bulb to one end of what you're testing and the other end of the first piece of wire to the other end of what you're testing. If what you're testing conducts electricity the current will run from the battery through what you're testing into the light bulb, out the other side of the light bulb and back to the battery and the light bulb will light up. If what you're testing doesn't conduct electricity, the electricity from the battery will not be able to pass through it to the light bulb and it won't light up. Good luck!
To replace an oven light in an electric oven, first, ensure the oven is turned off and unplugged for safety. Remove the light cover by either unscrewing it or twisting it counterclockwise, depending on the model. Take out the old bulb by gently pulling it straight out or unscrewing it. Finally, insert the new bulb and replace the light cover securely before plugging the oven back in and turning it on.

By Ohm's law, resistance is voltage divided by current, so the resistance of a light bulb can be measured by observing the voltage across it simultaneously with observing the current through it. Interestingly, the hot resistance is significantly different that the cold resistance, so measuring resistance with an ohmmeter will not give a meaningful resistance. This is because the resistance of a light bulb has a positive temperature coefficient. Take a typical 60 W 120V light bulb, for instance... Its cold resistance is about 16 Ohms. Calculate current and power at 120 V and you get 7.5 A and 900 W. The truth is that at 60 W, the bulb pulls 0.5 A and has a resistance of 240 Ohms.

recycle them into p pipes
1 nano secint
i millisecond
i think it takes about 10 seconds if you already have the light bulb in your hand.
3 weeks
Only two, as long as the light bulb has a hole, large enough for them to enter!
Does not decompose
i realy do not know
2 years
it took about a year and a half
As long as they are polish light bulbs 1
