If the battery generates the potential difference V V and you connect the capacitor to the battery through a conducting wire, as shown in your picture, once the equilibrium is reached each plate of the capacitor will have a charge Q = CV Q = C V, where C C is the capacitor capacitance.

What happens when a capacitor is placed in position 2?

As soon as the switch is put in position 2 a 'large' current starts to flow and the potential difference across the capacitor drops. (Figure 4). As charge flows from one plate to the other through the resistor the charge is neutralised and so the current falls and the rate of decrease of potential difference also falls.
