Solution:

A voltmeter is a high resistance device and is always connected in parallel with the circuit. While an ammeter is a low resistance device and is always connected in series with the circuit. So, to use ammeter in place of voltmeter a low resistance must be connected in parallel with the ammeter to make its resistance small.
