If the potential difference V is to be measured across the whole circuit, then across which 2 points will the voltmeter be connected in parallel? Draw a circuit diagram to illustrate the same.

Dear Student,

A voltmeter is always connected in parallel in the circuit to measure the potential difference between two points. It is because for measuring the voltage across some load in circuit the voltmeter must draw zero current, so voltmeter has a high value of resistance and is connected in parallel so that it draws no value of current.

So as you can see in the the voltage dropped by R1 is V it means that at the one end of the the resistance the supply is of V volts and at the other hand the supply is of 0 volts by ohms law so we have to connect our voltmeter parallel to taht circuit in order to measure voltag across the end of that circuit so that was alla
