Class12 physics why is voltmeter connected in parallel and ammeter in series
Answers
Because voltmeter always measures potential difference which can be measured by placing it parallel to the resistors but ammeter measures current and it can be measured by placing it in series
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.
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.
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
