Why can pencil lead can be used to make a light bulb?
A "pencil lead" is a mixture of the graphite allotrope of carbon mixed with clay and baked hard. While a pencil lead will conduct electricity, it can not be used to make a light bulb.
What effect would a pencil have on the brightness of a bulb?
A pencil has nothing to do with the brightness of a light bulb.
Is pencil lead is Pb free?
There is no lead in pencil - Pencil is made from graphite
What objects can lead be made into?
pencil . The 'lead' in a pencil is actually graphite.
Why does a circular fluorescent light bulb not light up fully?
A circular fluorescent light bulb may not light up fully due to issues such as a faulty ballast, aging tube, or poor connection with the socket. These factors can lead to insufficient power reaching the bulb, causing it to not reach its full brightness.
If a paper and pencil lead is connected to a light bulb circuit which one will turn on the light bulb?
The paper will not conduct electricity, so it will not light up the bulb. The pencil lead, on the other hand, can conduct electricity and complete the circuit, causing the light bulb to turn on.
Can a pencil lead light up a bulb?
No, a pencil lead cannot light up a bulb on its own as it does not conduct electricity. However, if a pencil lead is used as a component in an electrical circuit connected to a power source, it may help light up a bulb.
Why can pencil lead can be used to make a light bulb?
A "pencil lead" is a mixture of the graphite allotrope of carbon mixed with clay and baked hard. While a pencil lead will conduct electricity, it can not be used to make a light bulb.
What effect does the pencil lead have on the brightness of the bulb in a circuit?
The pencil lead does not have a significant effect on the brightness of the bulb in a circuit because it does not conduct electricity efficiently. In order for the bulb to light up brightly, the circuit needs an efficient conductor such as a metal wire to allow the current to flow easily and light up the bulb.
Is a light bulb older or a pencil?
pencil is older.
What effect would a pencil have on the brightness of a bulb?
A pencil has nothing to do with the brightness of a light bulb.
Why did the light bulb change brightness along the pencil?
because the pencil take the a litte enrgy.
Can a pencil lead light up using a battery?
Yes, A pencil lead can light up if you give it high voltage both live and neturalBut not to high
Can graphite let electricity turn on a light bulb?
No, graphite itself cannot conduct electricity in the same way as a metal wire. Graphite is a good conductor of electricity when in a specific form, such as in a pencil lead, but it is not typically used to power a light bulb without a complete circuit.
What would happen to the brightness of a bulb if you slid an alligator clip along the pencil lead?
The brightness of the bulb would decrease as the alligator clip moved along the pencil lead. This is because the resistance in the circuit would increase as the clip moves farther from the battery source, resulting in less current flow and therefore less brightness in the bulb.
What is the function of lead wires in a light bulb?
Lead wires in a light bulb are used to connect the filament to the electrical circuit. They conduct electricity from the power source to the filament, allowing it to heat up and produce light. Lead wires also provide support for the filament within the bulb.
What happens when you lick a light bulb?
Licking a light bulb can result in an electric shock and a burning sensation on the tongue. It is not safe to lick a light bulb as it can lead to injury or harm.
