What else can I help you with?
Does current flow through a resistor, or does it flow across a resistor?
Current flows through a resistor, not across it.
What is the name of pencil point?
The pointed end of a pencil where the graphite or lead is located is called the pencil tip or pencil point.
What is a good title for a science fair project about pencil resistors?
Pencil Circuts
Is a battery a resistor if not what is?
No, a battery is not a resistor. A battery provides electrical energy, while a resistor is a component that restricts the flow of current in a circuit.
What is the thickness of a pencil point?
The thickness of a pencil point typically ranges from 0.5mm to 0.9mm, depending on the type of pencil.
What is the purpose of the series resistor in test pencil?
The series resistor in a test pencil serves to limit the current flowing through the circuit when the pencil is used to detect voltage. This protection helps prevent damage to the tester and ensures user safety by reducing the risk of electric shock. Additionally, it allows for safe measurement of high voltages by ensuring that the current remains at a manageable level.
Can a pencil sharpened at both ends be used as a conductor?
Yes, but it will have high resistance so it would be better called a resistor than a conductor.
Is pencil lead a resistor?
It is not a resistor, but not to say it's a good conductor. Although it lacks the metallic bonding that makes Cu such a good conductor, the sheets of graphite have hybridized sp2 orbitals, meaning there are long rows of p orbitals that can share electrons across the sheet, meaning it can conduct electricity. It has a resistivity of ~20uOhm meters, whereas as Cu has a resistivity of ~17nOhm meters.
Can the graphite content in a pencil be used as a variable resistor?
Yes, the graphite content in a pencil can be used as a variable resistor by changing the length of the graphite material exposed. Increasing the length of the graphite path decreases resistance, while decreasing the length increases resistance. This can be useful in making simple electronic circuits or sensors.
How do you make a dimmer switch with a pencil?
To make a simple dimmer switch using a pencil, you'll need a basic understanding of electrical circuits and some tools. Start by using a pencil as a variable resistor (rheostat) in the circuit; connect the pencil's graphite to the circuit in place of a standard switch. As you adjust the position of the pencil, it will change the resistance, thus dimming the light. However, this is a very rudimentary method and not safe for actual electrical use; it's better suited for educational demonstrations rather than practical applications.
Is Light dependent resistor an example of resistor?
yes, a variable resistor
What am i i am usually as long as a new pencil To write my name you meed three words?
"A new pencil"."A new pencil"."A new pencil"."A new pencil".
Who invented the resistor?
Otis F. Boykin invented the wire precision resistor and the electrical resistor.
What is the difference between an ohmic resistor and a non-ohmic resistor?
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
What is the function of a cement resistor?
A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).
What are resistor values defined by?
Resistor value is defined by the Resistance the resistor offers in Kilo ohms/ohms value given by color codes on the resistor.
What you call pencil in Telugu?
It is called as pencil only.
