I have gotten an interesting varitey of responses to this query.
Some say the lowest power rating would be the max input. Others say
the power capability is multiplied for resistors in series (i.e., 2
10W resistors in series could handle 20 watts, 4 10W resistors could
handle 40 watts, etc.).
This question appears moderately important, and I think the list
would benefit from a public discussion, given the variety of
responses.
RS does sell an 8 Ohm, non-inductive, 20W resistor. If I put 6 of
these in series, does that mean it would handle 20W or 120W? 10W or
60W (half of calculated power under the various methods)?
