Question

what will be the result if a student connect voltmeter in series and ammeter in parallel in a circuit by mistake

Answer 1

Hey mate ☺️

Voltmeters in general have high resistance so that they consume very less current n indicates the Voltage across the terminals when connected in parallel..So when such high resistance is connected in series in a circuit.. Voltage drop 'll be high..

And an ammeter has low resistance n when connected in series, gives negligible voltage drop. If its connected in parallel, All the circuit current 'll be by-passed through this low resistance path n hence voltage drop 'll be more..

Both the wrong connections lead to power wastage.. sometime it even leads to open circuit in the connection.

Hope it helps you ☺️✌️✌️

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
