Answer:
The statement which is true:
- The potential difference across the capacitor decreases.
Explanation:
- As given that the capacitor is isolated that means that the charge on the plates of the capacitor remains the same.
- When the dielectric as mica is inserted then the capacitance increases.
- As well as the potential difference across the capacitor decreases which can be understood by the following equation:
V = Q / C
where V show potential difference across the capacitor, Q is the charge and C is the capacitance.
- As the capacitance increases the potential difference decreases and when the capacitance decreases the potential difference increases.
