Solution

A voltmeter is basically a galvanometer in a series combination with a very high resistance. So, a voltmeter would have a very high internal resistance. This is because in order to measure the potential difference accurately it has to prevent the flow of current through it as much as possible. A very high resistance solves that purpose.
As a result of this, voltmeters are connected in parallel in an electrical circuit.
For an Ammeter it is entirely opposite, it has a very low resistance to ease the flow of current through it.
