varistor Electr.|vɛəˈrɪstə(r)|
[f. variable a. + resistor.]
A semiconductor diode whose resistance varies non-linearly with the applied voltage.
1937Bell Telephone Q. Apr. 114 A varistor is a device, for example a copper oxide rectifier, whose resistance varies with the applied voltage. 1957Electronic Engin. XXIX. 386/1 Varistors exhibit a practical resistance variation of several decades over their normal rated working range of current or voltage. 1978Sci. Amer. Mar. 59/1 The compensation is termed equalization and is achieved by adding two varistors, or variable resistors, to the speech network. |
