A carbon pile resistor is made of a stack of carbon disks compressed between two metal contact plates. Adjusting the clamping pressure changes the resistance between the plates. These resistors are used when an adjustable load is required, such as in testing automotive batteries or radio transmitters.
Resistor based on the sheet resistance of carbon film. Sheet resistance is the resistance of a square piece of a thin material with contacts made to two opposite sides of the square. [1] It is usually a measurement of electrical resistance of thin films that are uniform in thickness.

Inks for electrodes, terminals, resistors, dielectric layers etc. are commonly prepared by mixing the metal or ceramic powders required with a solvent (ceramic thick film pastes) or polymer pastes [7] to produce a paste for screen-printing. To achieve a homogeneous ink the mixed components of the ink may be passed through a three-roll mill.

One difficulty in using nichrome or kanthal wire is that common tin-based electrical solder will not bond with it, so the connections to the electrical power must be made using other methods such as crimp connectors or screw terminals. Constantan (Cu 55 Ni 45) has a low temperature coefficient of resistivity; and as a copper alloy, it is easily ...
