what is ceramic resistor?

Question

what is ceramic resistor? where do we used ceramic resistors?

Answer 1

Resistors are use mainly to drop voltage and in doing this, heat is generated. Since this is a fairly inefficient thing to do, most electronic designs try to minimize the voltage drop and amount of heat generated. Sometimes there is no choice, and the heat a resistor generates is quite high and ordinary resistors would burn in half. In this case, a ceramic material is used for the body of the resistor because the ceramic handles high temperature fairly well. Like the tiles on the space shuttle.

Answer 2

Resistors are electronic components that provide specific amounts of resistance to an electrical current in electronic circuits. Ceramic resistors can fall into many different classes of resistors. Which classes these are often depend on who is describing the resistor. To a layman or electrician, a ceramic resistor is often any resistor encased in ceramic. Engineers and technicians, on the other hand, define ceramic resistors as those that use ceramics to control a resistor’s resistive value.

Ceramics are a very common internal component of many different types of resistors. In a carbon film or resistive wire resistor, the resistive material adheres to the outside of a ceramic core, usually in the shape of a cylinder. These cores provide a non-conductive base to hold the conductive components of the resistor in place, and give the resistor its general shape and size.

While an excellent electrical insulator, ceramic is also an excellent heat conductor. This property of ceramic allows the cores of these resistors to endure low to moderate power electrical current throughput without overheating and becoming damaged. Ceramic’s use, however, is not limited to the internal components of resistors.ceramic resistor seldom finds use in sensitive radio receivers or other devices particularly susceptible to interference.

Answer 3

ceramic resistors as those that use ceramics to control a resistor’s resistive value.Ceramic resistors are made of a combination of finely powdered carbon and ceramic material. These two powders combine in specific ratios to determine the final value of the resistor.
True ceramic resistors are widely used in many different types of electronic circuits and devices. While these types of resistors can endure very high operation temperatures, they also create significant amounts of electrical noise. Due to this fact, a ceramic resistor seldom finds use in sensitive radio receivers or other devices particularly susceptible to interference.

Answer 4

All of us have many ceramic resistors in our homes. Any circuit board will have ceramic resistors on them. So, TVs, computers, digital clocks, etc. The resistors are usually white with some paint around them. The paint is an indicator as to how many ohms it is rated for.

Answer 5

A Ceramic resistor or a stone resistor is another name for it
they are use for high voltage current and why it is called seramic and or stone resistor is cause it looks like a stone material
but it is not really stone it is a cement/plastic mixture I think (not sure what the cassing is made of but a resistor is a resistor all the way around sounds just as it works resist -a certain amount of current

Answer 6

A ceramic resistor is used to burn off excess energy and it does it by radiating heat

Answer 7

ceramic resistors are (obviously) ceramic based- they use specific formulas in the composition of the ceramic to achieve high degrees of accuracy in values (tolerance), high thermal stability, high voltage handling capabilities, and specific additional qualities.
