A current limiting resistor as set forth in claim 1, wherein one side of said intermediate terminal member is copper and the other side is stainless steel, said stainless steel side being welded to said end portion of said resistor.
Claim 4
Dependent Claim
98 words
A current limiting resistor comprising a length of metal having a positive temperature coefficient of resistance, said length of metal including a plurality of continuously joined sinuous segments in parallel spaced apart relationship, the distance which said segments are spaced apart being such to permit the magnetic field of one of said segments resulting from current flow therein to interact with the resulting magnetic field of an adjacent segment to substantially reduce inductance of a circuit in which said resistor is connected, said sinuously formed resistor is approximately 21 inches in length and approximately 0.091 inches in diameter.
