Question

C (e). Name the instruments used for measuring (i) current, (ii) potential difference.

Answer 1

Concept used: Electric current and potential difference

Step1: (i) Instrument used to measure the current

The instrument used for measuring the current is Ammeter.

It is always connected in series with the conductor through which the current is flowing.

Step2: (ii) Instrument used to measure the potential difference

The instrument used for measuring the potential difference is Voltmeter.

It is always connected in parallel to the two points across which the potential difference is to be measured.
