How will the rending of the ammeter change if the key K is closed?

In the Figure , what will be the reading of the ammeter and voltmeter, when the key K is closed ? The internal resistance of the cell is zero.

The diagram in Fig. shows a cell of e.m.f. epsi = 2 volt and internal resistance r = 1 ohm connected to an external resistance R = 4 ohm. The ammeter A measures the current in the circuit and the voltmeter V measures the terminal voltage across the cell. What will be the readings of the ammeter and voltmeter when the key K is closed.

Consider the following circuit : What would be the readings of the ammeter and the voltmeter when key is closed ? Give reason to justify your answers .

If the resistance R_1 is increased , how will the readings of the ammeter and voltmeter change?
