A student wants to investigate how the current through a filament lamp changes with the potential difference across it.
Which of the following shows the correct way to connect the ammeter and the voltmeter relative to the filament lamp to take these measurements?
Ammeter: in parallel; Voltmeter: in parallel
Ammeter: in parallel; Voltmeter: in series
Ammeter: in series; Voltmeter: in parallel
Ammeter: in series; Voltmeter: in series
