JEE AdvancedPhysicsCapacitorMultiple correct+4 / −2
A parallel plate capacitor having plates of area S and plate separation d, has capacitance C1 in air. When two dielectrics of different relative permittivities (ε\varepsilonε 1 = 2 and ε\varepsilonε 2 = 4) are introduced between the two plates as shown in the figure, the capacitance becomes C2. The ratio C2C1{{{C_2}} \over {{C_1}}}C1​C2​​ is JEE Advanced 2015 Paper 2 Offline Physics - Capacitor Question 12 English
