Question

what is the use of voltmeter and ammeterhow are they connected in circuit
​

Answer 1

A voltmeter is connected in parallel with a device to measure its voltage. An ammeter is a measuring device used to measure the electric current in a circuit.

Answer 2

Answer:

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 current.

Explanation:

Reason :-

An ammeter is connected series in a circuit. An ammeter is used to detect how much current is flowing through the circuit, so the Resistance of ammeter is very low by connecting it parallel to a circuit this may cause short circuit and burn the ammeter or the circuit.
