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.

What is the definition of electric bulb?
A glass sphere containing a metal element that glows when electricity is applied.
What is the part of the light bulb that glows?
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.
What is a circuit that lights up even if one bulb is out?
A parallel circuit lights up even when one bulb is out.
What would happen if you didn't have a light bulb for a circuit?
it would be ok in a circuit which didn't need a light bulb.
What job does a bulb do in a circuit?
The bulb converts energy from the power source into light and heat. It is the load in the circuit.
Why bulb glows continuously?
The bulb glows continuously probably, because the circuit it is installed in, is in the closed position.
Why a fuse bulb never glows again?
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.
What glows when an electric circuit is closed?
Examples are the tungsten element inside a light bulb, and the heating element bars of an electric fire.
Why does a bulb glow when electric passes through it?
When electric current passes through a bulb, it heats up the filament inside. This heat causes the filament to glow and produce light. The filament is made of a material that can withstand high temperatures without burning out.
Why does not a bulb glows with wee megger?
no current
Will a bulb glows when wood is attached to it?
huh? no, of course not!
What part of the bulb glows to produce light?
the filament
What is filament in a bulb?
The filament is the small coil that glows when the bulb is on. I believe its made out of tungsten
Is there gas when you turn on a light bulb?
yes, there is a gas in a light bulb you energise it and it glows.
A bulb glows dimly when current is passed through a vinegar solutionwhy?
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.
What is a bulb's job in a circuit?
The bulb is the load of the circuit, without it you have a short circuit.
Two bulb are connected in parallel one bulb glows brightly and other is dim what do you say about their current?
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.
