Parallel Plate Capacitor: Practice Problem & Solution

Solution Explained:

To solve this problem, we apply the core principles of Parallel Plate Capacitor. Understanding the underlying formula is key to arriving at the correct answer below:

Concept: Capacitance with dielectric.

Formula: (C' = KC), (Q = CV).

Solution: When a dielectric is introduced in a capacitor connected to a constant potential difference (V), the capacitance (C) increases to (KC). Since (V) is constant, the charge (Q = CV) must increase. Thus, extra charge flows from the source into the capacitor.
