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.
What else can I help you with?
Why Doesn't a lamp light up if the filament inside is broken?
If the filament inside a lamp is broken, it cannot conduct electricity properly, which is essential for generating light. The broken filament creates a gap in the circuit, preventing the flow of electricity needed to produce light. As a result, the lamp will not light up.
What happens if the filament breaks?
If the filament in a light bulb breaks, the circuit is interrupted and the light bulb will no longer illuminate. This is because the broken filament is unable to produce light when electricity flows through it.
Can electricity still pass through a bulb which has fused?
If the bulb lights up then electricity is passing through the bulb. If the bulb doesn't light up then electricity is not passing through.
When you connect a multimeter across an open component what is the reading?
When a multimeter is connected across an open component, the multimeter will display an infinite or overload reading. This indicates that there is no electrical continuity or path for current flow through the component, as it is disconnected or broken.
Why does the light bulb not work when the filament is broken?
A light bulb works by passing an electric current through the filament, which is usually made from a high resistance substance such as tungsten. When the current flows through, the filament glows which produces the light. When it burns out, no electricity passes and no glowing occurs. Source: i just know
Will the bulb light if the filament is broken Why?
No, the bulb will not light if the filament is broken because the filament is the part of the bulb that creates light when electricity passes through it. Without a functioning filament, there is no source of light in the bulb.
Can current flow through a bulb with a broken filament?
No, the broken filament breaks the connection which electricity needs to complete the circuit.
How do you Use filament in a sentence?
(Filament is a thread or thin wire.)Is the lamp unplugged or is the filament broken in the bulb?A silkworm's cocoon is made from a thin filament which can be twisted into thread.
Why Doesn't a lamp light up if the filament inside is broken?
If the filament inside a lamp is broken, it cannot conduct electricity properly, which is essential for generating light. The broken filament creates a gap in the circuit, preventing the flow of electricity needed to produce light. As a result, the lamp will not light up.
You are using a bulb whose filament is broken will the bulb glow when connected to battery give reason?
No, the bulb will not glow when connected to a battery if the filament is broken. The filament is the part of the bulb that heats up and produces light when electricity passes through it. If the filament is broken, there is no path for the electricity to flow through and generate light.
What the filament of bulb is broken then it is called?
If the filament of a bulb is broken, it is referred to as a "burnt out" or "blown" bulb. This means that the filament, which is the thin wire inside the bulb that produces light when electricity passes through it, is no longer connected and the bulb cannot function properly.
What happens if the filament breaks?
If the filament in a light bulb breaks, the circuit is interrupted and the light bulb will no longer illuminate. This is because the broken filament is unable to produce light when electricity flows through it.
If the filament of the bulb is broken would the circuit is complete?
no, the circuit won't complete
Why doesn't a bulb work when the filament inside it is broken?
A bulb doesn't work when the filament inside is broken because the filament is the component that allows electric current to flow through the bulb. When the filament breaks, it creates an open circuit, preventing electricity from completing the path and reaching the light-emitting part of the bulb. Without the flow of current, the bulb cannot produce light.
Why does a fused bulb not glow?
A fused bulb does not glow because the filament of a fused bulb is broken. Since current can't flow through the filament, it can't get hot enough to glow.
Can electricity still pass through a bulb which has fused?
If the bulb lights up then electricity is passing through the bulb. If the bulb doesn't light up then electricity is not passing through.
When you connect a multimeter across an open component what is the reading?
When a multimeter is connected across an open component, the multimeter will display an infinite or overload reading. This indicates that there is no electrical continuity or path for current flow through the component, as it is disconnected or broken.
