Capacitor question

2025 · 3 Apr · Shift 1 · Q59

JEE MainPhysicsCapacitorMCQ+4 / −1
A parallel plate capacitor is filled equally(half) with two dielectrics of dielectric constants ε1\varepsilon_1ε1​ and ε2\varepsilon_2ε2​, as shown in figures. The distance between the plates is ddd and area of each plate is AAA. If capacitance in first configuration and second configuration are C1\mathrm{C}_1C1​ and C2\mathrm{C}_2C2​ respectively, then C1C2\frac{C_1}{C_2}C2​C1​​ is: First Configuration JEE Main 2025 (Online) 3rd April Morning Shift Physics - Capacitor Question 4 English 1 Second Configuration JEE Main 2025 (Online) 3rd April Morning Shift Physics - Capacitor Question 4 English 2
