[Amps] Non-inductive resistors

[craxd]

Mike,
For smaller loads, I'd use a Globar resistor also. For the 20 Kw load, 
and to homebrew one with limited resources, they might look into this. I 
was thinking about those large grid resistors. If one had two of them, 
25 ohms each, but wound in opposite directions, it might work somewhat 
by seriesing them. This would be the same as that dual wound resistor in 
two sections with the different hand coils. The bifilar has a lot of 
capacitance due to the potential difference between the incoming and 
outgoing resistance wire. But, if this was broken up like the mentioned 
in sections, it may work also. One would have to use some sort of alloy 
tubing with the highest resistance you could get. For 20 Kw, were 
probably talking something like 3/4" diameter tubing with maybe a 1/8" 
thick wall or larger. Inco Alloys (Now named Huntington Alloys), has 
both the alloy mill (Huntington, WV.), and the tubing plant just down 
the road in Burnaugh, Kentucky. They make about every nickel alloy, 
(Inconel, Monel, etc.), and others you could mention. I had a friend who 
retired there and he may know about this, I'm not sure. Even using that 
figure eight pattern might be better. It has a figure eight wound every 
other turn so to continuously reverse the current flow from one turn to 
the next. With stiff enough tubing, this might be done without using a 
coil form.

I'd like to experiment with this some myself just to see what will work 
and what will not. For loads of 5 Kw and down, I'd stick with the Globar 
resistors.
