A student made an electric circuit as shown below



Is there any mistake in this circuit? If any then correct it.

Answer :

Here, in this circuit, the student has kept the ammeter in parallel and the voltmeter in series with the circuit.

But actually, the ammeter should always be connected in series as it has a very low resistance so when we connect the ammeter in series, maximum current will pass through it and thus the correct amount of current through the circuit can be measured.


In the same way, the voltmeter should always be connected in parallel as it is highly resistive due to which the current cannot pass through it and thus the current will pass through the component connected in parallel to it so as to measure the accurate voltage drop across the component.
