Temperature Coefficient of Resistor ke eng?
Tekanyo ea mocheso ea mohanyetsi, e hlalosoang ke letšoao α (alpha), e hlalosa kamoo khanyetso e fetohang ka mocheso. Hangata e hlalosoa ka likarolo ho milione ka tekanyo ea Celsius (ppm/°C). Ho na le mefuta e 'meli e meholo ea li-coefficients tsa mocheso: tse ntle le tse mpe.
Positive Temperature Coefficient (PTC): Li-resistors tse nang le mocheso o motle oa mocheso li bontša keketseho ea ho hanyetsa ha mocheso o ntse o phahama. Boitšoaro bona bo tloaelehile ho lisebelisoa tseo motlakase oa motlakase o ntlafatsang ka mocheso o phahameng, joalo ka li-oxide tse itseng tsa tšepe.
