Question

Air filled capacitor of capacitance $2\mu F$ is filled with three dielectric material of dielectric constants $K_1=4,K_2=4and{K}_3=6$ as shown in the figure. The new capacitance of the capacitors is

• A. $50\mu F$
• B. $2\mu F$
• C. $20\mu F$
• D. $10\mu F$

Answer 1

The correct option is D $10\mu F$

$\frac{{\in }_{0}A}{d}=2\mu F$

$C_{eq}=10\mu F$

$\therefore$ Option $D$ is correct.
