Capacitor With A Dielectric

Step 1: Understanding the arrangement: The total distance between the plates is , and a dielectric slab of thickness and dielectric constant is inserted between the plates. The remaining part of the gap is , filled with air. Step 2: Concept used — Series Combination of Capacitors:
The capacitor is effectively divided into two parts in series: - One with dielectric of thickness - One with air (dielectric constant 1) of thickness The capacitance for each segment: Step 3: Applying Series Formula:
