Question

Why voltmeter are connected parallel while ammeter are connected in series .

Answer 1

AS IN PARALLEL VOLTAGE REMAINS CONSTANT AND IN SERIES  CURRENT REMAINS CONSTANT SO IT IS USED TO MEASURE CURRENT AND VOLTAGE ALSO IN SERIES VOLTAGE DIVIDES AND IN PARALLEL CURRENT DIVIDES IT GIVES INACCURATE READINGS

Answer 2

Ammeter:-

• An ammeter is just a converted Galvanometer and measures the current flowing through the circuit by showing proportional deflection. An ammeter is formed by connecting a Galvanometer with a low resistance in parallel.

$\bigstar$So the Ammeter is connected in series with the circuit elements and measures the current flow in a circuit.

Voltmeter:-

• A Voltmeter is also a converted Galvanometer which measures the amount of Voltage (or) in other words the potential difference accross two points in a circuit. A voltmeter is formed by connecting a Galvanometer in series with a high resistance.

$\bigstar$So the Voltmeter is attached in parallel in a circuit and measures the voltage in a circuit.
