Hey there - first post on here from me...
I feel there's a point missing from the chapter about ammeter design. The sentence "The five-position switch makes contact with only one resistor at a time, of course." isn't entirely correct - the chapter fails to mention the 'make-before-break' switch needed for multi-range ammeters, since if you break the connection before making a new connection, you'll end up frying the meter, right?
