Question

Why do we connect ammeter in series and voltmeter in parallel?

Answer 1

Answer:

Explanation:

A voltmeter is a device which measures voltage across a resistor/load. If it is connected in series, then there would be some voltage drop across the voltmeter itself and hence, would not record the correct voltage across the resistor.

Similarly, an ammeter measures the current. If it is connected in parallel, then the current gets divided into different paths and the ammeter will not measure the actual current flowing through the resistor.

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
