Question

Why voltmeter is connected in parallel in a circuit

Answer 1

Voltmeter is used to measure potential difference.It is always connected in parallel across the points where the potential difference is to measured so one end of the voltmeter is connected to the point A of a resistance AB and the other end to the point B,and also it has a high resistance so that it takes a negligible ...

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 the 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..
