A METHOD OF MANUFACTURE OF ELECTRICAL RESISTORS COMPRISING FORMING A STRAIGHT CORE, FASTENING NUMBER OF TERMINALS AT LONGITUDINALLY PREDETERMINED SPACED INTERVALS ON SAID CORE AND LONGITUDINALLY ARRANGED IN PAIRS, SAID CORE HAVING A CLEAR PORTION BETWEEN PAIRS, MOUNTING RESISTIVE WIRE ELEMENTS AROUND SAID CORE BETWEEN RESPECTIVE PAIRS OF TERMINALS AND ATTACHING AND TERMINATING SAID ELEMENTS THERETO TO FORM A PLURALITY OF LONGITUDINALLY SPACED RESISTORS WITH SAID CLEAR PORTIONS THEREBETWEEN FORMING A SOLID INSULATING PROTECTIVE COATING ON SAID CORE TO COVER SAID RESISTIVE WIRE ELEMENTS AND SEVERING SAID CORE BETWEEN THE TERMINALS OF ADJACENT RESISTORS TO FORM INDIVIDUALLY SEPARATE RESISTORS.
