In which diagram(s) (labeled A - D) does the ammeter correctly measure the current through the battery?
I don't believe there are any here, just to know that the ammeter is in series with the current that is passing through it and is measuring that current.
The Attempt at a Solution
The thing is I'm not sure where the current is coming out of, would I be correct in saying the emf is the source of the current throughout the whole of the battery? If that was the case I was thinking the only current that the ammeter is in series with with battery C but that answer was incorrect (masteringphysics), or would it be that the ammeter is in series with the potential difference measured by the voltmeters?
any help is greatly appreciated.
