Resistor Terms:



'A', 'B/C', 'D/E', 'F-M', 'N', 'P', 'R', 'S', 'T', 'V'

Variable Resistor: A resistor that changes value with applied voltage. Also called a Potentiometer, Trimmer, or Rheostat. Companies that Manufacturer Variable Resistor

variable resistor

Varistor: A resistor that changes value with applied voltage. Companies that Manufacturer Varistors

Voltage Rating: Resistors shall have a rated direct current (dc) continuous working voltage or an approximate sine-wave root-mean-square (rms) alternating current (ac) continuous working voltage at commercial-line frequency and waveform corresponding to the power rating, as determined from the following formula:

Wirewound: A Resistor made up of resistance wire, wound on an insulated form. A wirewound resistor may be variable or fixed.
