Question

Draw a circuit to veritfy ohms law . Explanin why ammeter is connected in series and voltmeter is connected in parallel in any electrical circuit

Answer 1

1)ammeter has very less resistance
2) it has to measure all the current in a circuit
So ammeter is connected in series


1) voltmeter has very high resistance, which if connected in series, then current flow stops
2) it has to measure terminal potential difference
So it is connected in parallel

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.
