Question

Why ammeter is always connected in series and voltmeter in parallel connection?

Answer 1

In order for a voltmeter to measure a device's voltage, it must be connected in parallel to that device . This is necessary because objects in parallel experience the same potential difference. n ammeter measures the electric current in a circuit. ... This is necessary because objects in series experience the same current.

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.

And if this is not maintained then there is a high chance for the ammeter to get damaged due to low resistance
