Solution

A voltmeter is used to measure the potential difference across two point in a circuit. Since, in parallel connection the voltage in the branches remains same, and also the resistance of the voltmeter is very high due to which a very small current flow through the voltmeter. So, it is connected in parallel to measure the voltage.

Q. Why should an voltmeter have a very high resistance ?

Q. Assertion :All electric devices shown in the circuit are ideal. The reading of each of ammeter (a) and voltmeter (V) is zero. Reason: An ideal voltmeter draws almost no current due to very large resistance, and hence (V) and (a) will read zero.
