increasing the temperature, resistance decreasesthen it is): |
Answer» <p>Thermistor with this particular temperature behavior are commonlysemiconductors. In a semi-conductor, there is an energy gap between the (filled) valence and the (empty) conduction band. At zero temperature, no charges are in the conduction band and the resistance should be infinite as the system behaves basically like an insulator.</p><p>If you turn on the temperature, some electrons will start to occupy the conduction band and thus contribute to conduction, lowering the resistivity.</p> | |
