There is a concept that one must understand when working with electricity; "electrical current will always take the path of least resistance."
Many people don't understand the difference between a "short" circuit and an "open" circuit.
An open circuit is when there is effectively no return path from the electrical source back. It's like when a light switch is turned off and the light isn't on.
A SHORT circuit would be when the light switch is turned on but another wire is across the same wire pair, resulting in an effectively shorter path between the conductors of the power source. The electrical current then takes the path of least resistance, leaving no electrical current for the bulb.
Naturally, there is that gray area between a short circuit and an open circuit, that's where things run properly... in general.
Switch
A glass sphere containing a metal element that glows when electricity is applied.
In an incandescent lamp, it is called a filament. It is usually made out of Tungsten. The resistance in the filament causes it to heat up, and then glow. In a neon lamp it is plasma, which is an ionized gas. In a fluorescent bulb mercury vapor is ionized to produce UV radiation, that hits the phosphor coating on the outside of the bulb and that glows.
A parallel circuit lights up even when one bulb is out.
it would be ok in a circuit which didn't need a light bulb.
The bulb glows continuously probably, because the circuit it is installed in, is in the closed position.
A fuse bulb contains a small wire that melts to break the circuit when the current exceeds a certain level, protecting the circuit from damage. Once the wire melts, it needs to be replaced in order for the bulb to glow again.
Examples are the tungsten element inside a light bulb, and the heating element bars of an electric fire.
no current
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 is the load of the circuit, without it you have a short circuit.
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.
