Question

By mistake, a voltmeter is connected in series and an ammeter is connected in parallel, with a resistance in an electrical circuit. What will happen to the instruments?

Answer 1

Answer:

By mistake, a voltmeter is connected in series and an ammeter is connected in parallel, with a resistance in an electrical circuit. ... When it isconnected in parallel with a resistance, the weak current flowing through the circuit willpass through the ammeter. Due to it, theammeter will not show appreciable deflection.

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
