no current

I did them with a 1,000 volt megger .
Megger Group Limited was created in 1889.
It is the terminal on the megger that the ground cable connect to when testing a device to ground.
yes
The bulb glows continuously probably, because the circuit it is installed in, is in the closed position.
The thin wire in an electric bulb that glows is called a filament. It is typically made of tungsten and glows when electricity passes through it, producing light.
huh? no, of course not!
the filament
yes, there is a gas in a light bulb you energise it and it glows.
The filament is the small coil that glows when the bulb is on. I believe its made out of tungsten
The bulb glows dimly when current is passed through a vinegar solution because the small number of ions in the vinegar solution move through the filament of the bulb.
The bulb that glows brightly likely has a higher current passing through it compared to the dim bulb. This could be due to differences in resistance, voltage, or power ratings of the two bulbs.
The supporting metals are insulated from the current path and current cannot flow.
The part of a light bulb that glows is called the filament. It is typically made of tungsten and emits light when an electrical current passes through it, heating it up to produce light.
fluorescent bulbs have mercury in them. There are heaters at the ends of the bulb that vaporizes the mercury to allow the light to be produced ( the fluorescence on the inside of the bulb is what actually glows). If the bulb is cold you do not get the ionization of the mercury to cause the fluorescent powder inside the bulb to glow, or it just glows a small amount.
An incandescent bulb.
