Question

The figure shows a capacitor having three layers of equal thickness and same area as that of plate . the layer first is vaccum , second is conductor and third is dielectric of dielectric constant $K$ . The ratio of energy stored in region three to total energy stored in capacitor three is :

• A. $\frac{1}{K+1}$
• B. $\frac{3}{K+1}$
• C. $\frac{4}{K+3}$
• D. $\frac{4}{K+1}$

Answer 1

The correct option is A $\frac{1}{K+1}$

Hence, option $A$ is correct answer.
