Question

State the purpose of using the following in an electric circuit (i) Ammeter (ii)

Galvanometer​

Answer 1

Explanation:

An ammeter is a measuring device used to measure the electric current in a circuit.

&

At the heart of most analog meters is a galvanometer, an instrument that measures current flow using the movement, or deflection, of a needle. The needle deflection is produced by a magnetic force acting on a current-carrying wire.

Answer 2

Answer:

1. An Ammeter is a measuring device used to measure the electric current in a circuit. A voltmeter is connected in parallel with a device to measure its voltage, while an Ammeter is connected in series with a device to measure its content.
2. Galvanometer is an instrument for measuring a small electrical current or a function of the current by deflection of a moving coil. The deflection is a mechanical rotation derived from forces resulting from the current.
