You mean positive temperature coefficient? Yes conductors as they get heated then due to the nucleii vibrating with greater amplitude would have a grip over the moving electrons and so the resistivity increases with the increase in temperature. Hence positive temperature coefficient.
What else can I help you with?
What is positive coefficent and negative co efficient of material?
of resistance ?
What is difference between positive and negative conductor?
There is no positive and negative conductor. There are just two ends of a conductor, namely positive and negative. It is usually said that electricity flows from the positive to the negative side of a conductor, but scientists have discovered, that current consists of electrons that always flows from the negative to the positive side.
What is coefficent in math?
The number in the front of the equation. Example 2x-3k..so the 2 nd the 3 are the coefficent.
Does a conductor has many positive electrons?
No, a conductor does not have "positive electrons". Positive electrons are positrons, particles of anti-matter. A conductor, because if it's atomic structure, allows electrons to flow more freely from one atom to the other, thus creating electricity.
Is wire an example of a conductor?
It matters what kind of wire like a cell phone charger would not be a conductor but a wire made for braces would be a big conductor. Also anything metal is a positive conductor of electricity. :)
What is the coefficent of 5a plus 2?
The coefficient is 5.
Who coined the term Lift Coefficent?
Otto Lilienthal
Is the electric current in a metal conductor is carried by positive ions?
Yes
What is the name for a positively charged conductor through which electrons flow into a device?
Anode The name for a positive charge conductor through which electrons flow into a device is called the life conductor.
How does one charge a conductor negatively if you have only a positively charged rod?
You can use induction to charge a conductor negatively with a positively charged rod. Bring the positively charged rod close to the conductor without touching it. This will cause the electrons in the conductor to move away, leaving positive charges behind and making the conductor negatively charged.
If a carbon resistor increases in temperature its resistance will?
This depends on the type of conductor. If the conductor has a positive coefficient the resistance will increase. If the conductor has a negative temperature coefficient the resistance will decrease.
The number factor of a variable term is called the?
numerical coefficent
