Hi Guys
For a homework question I have been asked to design a theoretical resistor, but I don't really know where to start and I cannot really get any help from my teacher as it is assessed and so no help can be given. The question is as follows...
Design a simple, compact and non-inductive 1k ohm resistor based on wire that is 20micro metres thick with a resistivity of 147.47 micro ohm centimetre. the wire is covered with a 5 micro metre layer of insulation with a relative permittivity of 2.3.
My first thoughts are that a resistor made with a straight wire will be far too long, but if i coil the wire then i will be creating a helical coil which will therefore be inductive and the question states it should be "non-inductive."
I can only think that some design that possibly cancels the inductiveness by reversing the coil directions could help, but apart from that i dont really have a clue.
If anyone could help in any way it would be greatly appreciated.
