Question

The following circuit diagram shows the experimental set up for the study of dependence of current on potential difference. The two circuit components which are connected is series are (a)Battery and voltmeter
(b) Ammeter and voltmeter
(c) Ammeter and rheostat
(d) Resistor and voltmeter​

Answer 1

Answer:

Ammeter and rheostat are connected in SERIES

Explanation:

Pls mark as brainliest

Answer 2

(c) Ammeter and rheostat

Clearly the ammeter and resistor are connected end to end, thus they are in series. Also resistor and rheostat are in series, sine they are also joined end to end. So, the ammeter and rheostat are in series.
