How do you connect an ammeter and voltmeter in an electrical circuit? Why?
Answers
Voltmeter is connected in parallel as it is used to measure the voltage. Ammeter is connected in a series as it is used to measure the amount of current flowing through the circuit
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.
