what happens when you connect a battery with a light bulb with a single wire?

Answer 1

No, of course not! You are wrong. I have tried wrapping the wire around but it doesnt work. What you have to do is connect one end of the wire to a battery and tape it on just to make sure it doesnt get loose.

What you do wih the other end of the copper wire is connect it to the bulb and once again, tape it on just incase it doesnt get loose.

It Doesnt Work Beacause The Copper Wire Is Not Strong Enough To Make Electicity Pass Through So Dont Bother Trying it

with standard household 120ac it will NOT light up. but you can get it to work by using really high voltages (several thousands volts or higher. the electricity has to have enough volts in order to ionize the gas inside the bulb....however it will not light up in its normal fassion, but instead will just ionize the gas inside and that will glow a different color depending on the composition gas inside the bulb. This will still work even if the filament is broken. also if it is broken you can run a wire to the base of the bulb and the other on the screw side. this will cause a "arc" between the filliment holders which will glow as i said before.

i have got purple for most of my bulbs, some blue it all depends on the voltage and the gas inside.

and YES copper is strong enough as long as the amps arent high (amps is what will cause a wire to burn up or short out) but with a low amp high voltage copper wire will work.

I know this because i have don't it many times, all you need is a high voltage low amp source to do it.

neon sighn Transformers work great....and thas what i use majority of the time. But i am buying a device that is intended for experiments, you can adjust the amount of voltage from 10k - 60k. this type of machine is perfect for high voltage electrical experiments

Answer 2

Yes, the bulb will light up.

However, and this is critical, it is illegal (at least in the US and Canada) to connect a load between hot and ground. You have to connect the load between hot and neutral. (Or between hot and hot.) Ground is reserved for protective earth ground, i.e. chassis or frame ground, and you are not allowed to pass operating current on ground.

Answer 3

Only if the voltage is correct. If you connect a 110V lamp to a 12 V battery, you won't see much.

When you connect a 1,5V lamp to a 12V battery, it will burn out.
