Answer:
It must be placed in series with the measured branch , and must have very low resistance to avoid significant alternation of the current it is to measure .Voltmeter has high resistance because it measures the voltage difference between two different points, but it should not change the amount of current going through ..

Hello!!
The resistance of a voltmeter should be high, because voltmeter is connected parallel to the component of a circuit and it also takes negligible current from the circuit in order to measure the potential difference accurately.
Hope it helps!!
