PHY 102 Coulomb's law and Electric Fields Objective Question
Take CBT

Question

If a capacitor is filled with a dielectric material of constant K, how does its capacitance compare to the same capacitor with vacuum between its plates?
Options
A Its capacitance is K times smaller.
B Its capacitance is K times larger.
Correct Answer
C Its capacitance remains unchanged.
D Its capacitance increases by K².
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 12 states: 'For vacuum, K = 1, so that a dielectric-filled parallel-plate capacitor has a capacitance K times larger than the same capacitor with vacuum between its plates.'

Hint

The dielectric constant K is a multiplier that enhances capacitance when a dielectric material is introduced.
