So, at 1Hz the law has changed, eh? What new law do I need to use?


The laws are exactly the same for dc as ac, just at dc the frequency
dependant parts tend to the point that they are of no consequence.

Thanks, Jeff. I agree, of course.

The thinking that the laws of physics suddenly change when AC is so slow
that it suddenly becomes DC is probably about as sound as my
tongue-in-cheek suggestion that a SWR suddenly ceases to exist if there
is no reflection. ;o)
