🧠 Compound Dielectric: Split Into Parallel and Series Sub-Caps

Read the figure. A parallel-plate cap with multiple regions of different dielectric constants. Some are stacked along the field direction (series), and some are side-by-side perpendicular to the field (parallel). The answer takes the form  — meaning the "effective dielectric constant" (relative to a baseline ) is .

The first move is to identify each sub-region, write its individual capacitance using , and then combine them accordi
