If the filament of the bulb is broken would the circuit be complete?

If the bulb's filament is broken, the whole circuit becomes open. If the bulb is in a series circuit or is the only bulb, the electricity would no longer flow. If the bulb is in a parallel circuit, along with other bulbs, then only the blown bulb would go out, and the other bulbs would still work.

How do you make a light bulb work without electricity?
No power is used. The lamp in the light fixture is the load of the circuit. The load resistance is what makes the current flow. When the current flows through the filament's resistance, heat and light are generated. With no lamp in the fixture, the circuit's voltage potential is still at the socket contact points and if touched could cause you a shock. This is a good reason to shut the fixture off at the switch when removing the burnt out bulb and replacing it with a new one.
What would happen if one of a set of light bulbs burn out in a parallel circuit?
It depends on the circuit. If it is a constant-current circuit, any light bulbs connected in parallel with it will become brighter. If it is a constant-voltage circuit like a typical household circuit, nothing will happen. Any connected in series with it will go out.
I am trying to make a simple balloon detonator using an rf remote but the instruction states i need small gauge filament what is this?
A small gauge filament is a thin wire with a high melting point, just like the filament in light bulbs. That filament will heat up when electricity will pass through it. If you have enough battery power, I would suggest using a piece if pencil lead.
How do light-bulbs work?
An electric current passes through a thin filament, heating it until it produces light. The enclosing glass bulb prevents the oxygen in air from reaching the hot filament, which otherwise would be destroyed rapidly by oxidation.
What would be different about the circuit if a resistor were added in series with the light bulbs?
The total current in the circuit will decrease.
If the filament of the bulb is broken would the circuit is complete?
no, the circuit won't complete
What happens when a bulb gets fused?
When a bulb fuses the circuit is broken if it is on a serial circuit. If the bulb is on a parallel circuit, only the fused bulb will go out, any other bulb would remain lit. On a serial circuit, until the bulb is replaced by a new one, the circuit is not able to be used.
What happens if one bulb in a series circuit burned out?
In a series circuit, all bulbs are necessary to complete the circuit. If one bulb goes out, the circuit is broken, so none of the bulbs would light up.
What would be the voltmeter reading if the lamp across which it is placed has a broken filament?
A voltmeter connected across the broken (open) filament of a light bulb reads the full voltage of the power supply whether the bulb is in a series or parallel circuit. -- In a series circuit with other components in series with the bulb, this reading tells you that at least one of the components is open, possibly the filament. -- In a parallel circuit with other components in parallel with the bulb, or with the bulb connected directly to the power supply, this reading tells you nothing ... the voltmeter reads the full power supply voltage whether the bulb is open or good. The voltmeter isn't a very helpful measurement to identify an open filament. An ohmmeter, with the power to the circuit turned off, is much more helpful.
Why is a copper wire not used to make filaments of electric bulbs?
Because the filament is in effect a resistor. Copper is too good a conductor to provide resistance to the current, and would simply allow the current to complete the circuit. The light is generated by the filament glowing as it heats up in resistance to the current. Tungsten is a much better resistor.
What would happen if you stuck an insulator in the middle of a circuit?
the circuit would not be complete. the lightbulb would not light or the buzzer would not buzz
Why does a energy efficient bulb not complete a circuit?
There is no element to heat to complete the circuit. Another example would be magnetic induction lighting.
What is an complete circuit?
A circuit is complete whenever current can flow from the battery (or what is producing current), through the circuit, and back to the battery. A complete circuit could contain just a battery and one wire. An incomplete circuit could be a battery with a wire attached to just one terminal, because current cannot flow all the way through the circuit in this case (i.e. cannot flow through the battery). note: not all elements in a circuit may have current flow in a complete circuit. For instance, a light bulb may be shorted but you still have a complete circuit.
Can you measure a vacuum tube using ohmmeter?
Maybe, but not sure info would be useful. You can use ohmmeter to check that a tube's filament is intact. Broken/burned-out filament is most likely reason for dead tube.
Would a4 paper complete a circuit?
No paper is an insulator.
Why doesn't a bulb work when the filament inside is broken?
The filament in a light bulb (the part that glows bright) is usually made from a metal called tungsten which has such a high melting point that it can heat up as electricity is passed through it and give off light without melting at the high temperatures produced. However, at high temperatures, tungsten can also burn - so if a current is passed through the fillament under normal conditions, it will heat up, glow, but because it is so hot, it will react with the air around it and either vaporise or burn, becoming useless. To prevent this happening, the filament is enclosed in a glass bulb. In the bulb all the air is removed and another gas is put in instead. In cheap bulbs this is usually nitrogen, but more often the gas used is argon. Neither of these gases will allow burning, and so the filament can glow brightly when electricity is passed through it without the risk of it burning. However, if the glass bulb is broken - or even if it is simply cracked - air containing oxygen can get in and so when you switch on the bulb the hot filament burns away rapidly blowing the bulb.
