Question

A sheet of mica is inserted between the plates of an isolated charged parallel-plate capaci tor. Mica is a transparent mineral that comes naturally in thin sheets, and is an excellent dielectric. Which of the following statements is true? 1. The electric field between the capacitor

Answer 1

The statement which is true:

• The potential difference across the capacitor decreases.

Step-by-step 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.
