Question

Name the device used to measure electric current and potential in the circuit . How are they connected and why.

Answer 1

Explanation:

the device used to measure electric current in a circuit is AMMETER and it is connected in SERIES.

the device used to measure POTENTIAL DIFFERENCE is VOLTMETER and it is connected in PARALLEL.

Answer 2

Answer:

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

• A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric 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 current.

• 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.
