Show Hint
For capacitors with multiple dielectrics, the effective dielectric constant can be calculated using the formula for series or parallel combinations.

- \( K_1 + K_2 \)
- \( \frac{K_1 K_2}{K_1 + K_2} \)
- \( \frac{K_1 + K_2}{K_1 K_2} \)
- \( \frac{2K_1 K_2}{K_1 + K_2} \)

The Correct Option is C
Solution and Explanation
For a parallel plate capacitor filled with two dielectric materials, the effective dielectric constant is given by the formula \( \frac{K_1 + K_2}{K_1 K_2} \), considering the properties of the materials.
Step 2: Conclusion.
The correct ratio is \( \frac{K_1 + K_2}{K_1 K_2} \), corresponding to option (c).
Step 2: Conclusion.
The correct ratio is \( \frac{K_1 + K_2}{K_1 K_2} \), corresponding to option (c).
