An ammeter and a voltmeter are connected in series to a battery of emf E=6.0V . When a certain resistance is connected in parallel with the voltmeter, the readding of the voltmeter decreases two times, whereas the reading of the ammeter increases the same number of times. Find the voltmeter reading after the connection of the resistance.

The plates of a parallel plate capacitor are connected to an ideal voltmeter. What will happen to the reading of the voltmeter if the plates of the capacitor are brought closer to each other in an insulating medium?

In the circuit shown, A and V are ideal ammeter and voltmeter respectively. Reading of the voltmeter will be
