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.
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?
The filament in the bulb has resistance. The current flowing through the resistance of bulb causes the filament to dissipate energy in the form of heat and light. The filament is actually glowing white-hot because of the energy it is dissipating, thus giving off light.
Why does not a bulb glows with wee megger?
no current
Why a fuse bulb never glows again?
Because it slept with another fuse bulb so the bulbs wife seperates the fuse bulb so thats why it never glows cuz its sad! :c
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
Which type of light bulb glows when a filament inside it gets hot?
An incandescent bulb.
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.
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
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.
