An ammeter and a voltmeter are connected in series to a battery of emf 6V. When a certain resistance is connected in parallel with the voltmeter, the reading of the latter decreases n = 2 times, whereas the reading of the ammeter increases the same number of times. What is the ratio of the voltmeter resistance to the ammeter resistance? Find the voltmeter reading after the connection.

In ac circuit when ac ammeter is connected it reads i current if a student used dc ammeter in place of ac ammeter the reading in the dc ammeter will be:
