What Is Ceramic Resistor

They can withstand high energy and high voltages at high temperatures such as those encountered in the protection of high voltage surge equipment discharge.

What is ceramic resistor.

The ballast resistor is commonly found in older vehicles because they did not have the benefit of circuit boards found in most of today s vehicles. Ceramic resistors are chemically inert. Standard resistors have four color bands. To a layman or electrician a ceramic resistor is often any resistor encased in ceramic.

A wire wound resistor is a resistor where a wire with a high resistivity is wrapped around an insulating core to provide the resistance. Over time the ballast resistor can be damaged by normal wear and tear so there are a few things to look for when you suspect a bad or failing ballast resistor needs servicing. Engineers and technicians on the other hand define ceramic resistors as those that use ceramics to control a resistor s resistive value. More examples include a 1 ohm resistor 220 ohm resistor and 1k resistor.

Often a 10k ohm resistor is handy for pull up and pull down situations which we will discuss later. 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. Electrical electrical units amps and electrical wiring wire gauge and awg electrical formulas and motors. Three of the bands tell you the nominal value which means the value the resistor was designed to have the fourth band tells you the tolerance of the resistor which indicates how far off the nominal value the actual resistance could be.

Resistors color codes calculator color codes for fixed resistors. A ceramic resistor or a stone resistor is another name for it. Ceramic resistors are manufactured from a sintered body of ceramic material with conductive particles distributed throughout the matrix to produce a resistor that is 100 active and non inductive. Parallel circuits resistance voltage and current in parallel networks.

The manufacturing process isn t perfect so most resistors are a little off. The whole resistor is enclosed in a flameproof ceramic layer. A 10k resistor which means 10 000 ohms of resistance is one of the most commonly used. 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.

Another popular value is a 100 ohm resistor. Example of a wire wound resistor construction. Electrical resistance in serial and parallel networks resistors in parallel and serial connections. Metal film resistors are also available in high power types with power ratings less than wirewound types typically less than 5w but having closer tolerances.

Wire wound resistor construction varies widely. Back to main picture. High power metal film. They are useful for limiting current.
