What Is Ceramic Resistor

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.

What is ceramic resistor.

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. 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 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. The manufacturing and choice of materials used is dependent on the way the resistor will be used in.

Engineers and technicians on the other hand define ceramic resistors as those that use ceramics to control a resistor s resistive value. High power metal film. A resistor is an electronic component that can lower a circuit s voltage and its flow of electrical current. Standard resistors have four color bands.

A wire wound resistor is a resistor where a wire with a high resistivity is wrapped around an insulating core to provide the resistance. 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. There are two main types of resistors. They can withstand high energy and high voltages at high temperatures such as those encountered in the protection of high voltage surge equipment discharge.

More examples include a 1 ohm resistor 220 ohm resistor and 1k resistor. Resistors color codes calculator color codes for fixed resistors. They are useful for limiting current. Another popular value is a 100 ohm resistor.

A 10k resistor which means 10 000 ohms of resistance is one of the most commonly used. Example of a wire wound resistor construction. Ceramic resistors are chemically inert. A ceramic resistor or a stone resistor is another name for it.

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. Often a 10k ohm resistor is handy for pull up and pull down situations which we will discuss later. Parallel circuits resistance voltage and current in parallel networks. 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.

The whole resistor is enclosed in a flameproof ceramic layer. Electrical resistance in serial and parallel networks resistors in parallel and serial connections. Back to main picture. To a layman or electrician a ceramic resistor is often any resistor encased in ceramic.
