The only way I can really think of is to look at it, because of carbon's gray appearance it should be pretty easy to tell.
This depends on the type of resistor. Carbon composition and metal film resistors typically will burn open, carbon film types can short.
carbon
It's a wireless compressed carbon-based resistor that has coloured rings around it to indicate its value in Ohms based on a predefined code.
A 10K resistor has the coloured stripes in the following order.. Brown, Black, Orange, Gold
A: Lots of significant difference metal has better stability with the environment it can be laser ed with precision and carbon is usually more noisy
Radiocarbon dating is a technique that uses the decay of carbon-14.
Which type of resistor is commonly used in automotive circuits?
there might be ways to get the power rating by measuring the size of the resistor. but as the physical size of the resistor increases, its power rating also increases..
1.)Linear Resistor 2.)Non Linear Resistor a.)Fixed Value Resistor b.)Variable Resistor c.)Package Resistor Taking into account compositon: 1.) Carbon piece 2.) Carbon Deposition 3.) High Volatge Ink Film 4.) Metal Film 5.) Metal Glaze 6.) Wire Wound 7.) Ceramic Metal
Same as any other kind of resistor, they're used to control voltages and currents in electric circuits.
A trimmer resistor usually called a trim pot is a small variable resistor it is used in circuits to do preset it is trimmed with a trimmer screwdriver it is made up with a round fiber disc with a layer of carbon with a wiper that run on the carbon layer to change the resistance it always have 3 connecting pins where the center one is connected to the wiper and the other two to opposite ends of the carbon strip.
A: You may find some traces of the color code bands if not there is not way to determine its value with a VOM the carbon residue will falsely deviate the value . Cleaning with it with a alcohol will help but to be certain there is no way
