Ceramic Resistor Uses

Depending on the resistance required pitch diameter and length of the carbon spiral vary.

Ceramic resistor uses.

Ceramic and metal oxide if you need a high power non inductive resistor you can use cermet ceramic metal mix or metal oxide resistors. A spiral is etched on the deposited carbon which turns it into a wire wound on a ceramic core. A ceramic substrate that has a thin bulk metal foil cemented to it makes up the resistive element. A resistor is a passive two terminal electrical component that implements electrical resistance as a circuit element.

Adjustable resistors there are many different types of adjustable resistors. These are constructed much like a carbon comp resistor substituting the cermet or metal oxide for the carbon composition material. This is my favorite image to show people. This makes use of two resistors to divide a voltage by the ratio of their resistances.

Uses of carbon resistors. As seen above resistors can be used to limit the current that flows into a device. The construction of a true ceramic resistor often called a carbon composite resistor is different from most other types even though it also uses ceramics. The simplest most often have the most uses and the resistor follows this statement exactly.

The carbon resistor contains carbon coated onto a ceramic core. These two powders combine in specific ratios to determine the final value of the resistor.
