So next time you get a student in electrical class who decides that 240V into 10 ohms gives 2 amps, don't tell him he's wrong, just say he has "a unique perspective on the problem" so as not to cause him the terrible humiliation of getting his sums wrong.
And given the
Dumbplex heater as included in my recalls thread, it looks like pauluk called it there.
By now it's a wonder that
anything basic ever gets done well...
