give an operational definition of "in series." Voltmeter & Ammeter This site contains a definition, diagram, and equations
for a voltmeter and an ammeter. What are the central characteristics
of "ideal" voltmeters and ammeters?
Example: the Wheatstone Bridge
This is a nice example of a real electrical engineering tool
(the Wheatstone bridge). Take Chapter 23 a bit farther and describe
