Answer 2

Answer:

C) Rheostat

Explanation:

Ammeter - An ammeter is a measuring instrument used to measure the current in a circuit. Electric currents are measured in amperes (A), hence the name. The ammeter is usually connected in series with the circuit in which the current is to be measured.

Voltmeter - A voltmeter is an instrument used for measuring electric potential difference between two points in an electric circuit. It is connected in parallel.

Rheostat - It is an electrical instrument used to control a current by varying the resistance.

Galvanometer​ - A galvanometer is an instrument that can detect and measure small amounts of current in an electrical circuit.
