3. 2C and V

Explanation:

In a parallel combination of capacitors, the potential difference across the capacitors remain the same, as the right-hand-side plates and the left-hand-side plates of both the capacitors are connected to the same terminals of the battery. Therefore, the potential remains the same, that is, V.

For the parallel combination of capacitors, the capacitance is given by

C_eq = C₁ + C₂

Here,

C₁ = C₂ = C

$\therefore$ C_eq = 2C
