QJEEM19Ph5224: JEE Main 2019 Physics - Class 12 JEEM19Ph5224 Solution: The parallel combination of two air filled parallel plate…

The parallel combination of two air filled parallel plate capacitors of capacitance C and nC is connected to a battery of voltage, V. When the capacitors are fully charged, the battery is removed and after that a dielectric material of dielectric constant K is placed between the two plates of the first capacitor. The new potential difference of the combined system is :-

Multiple Choice Options

  • A V
  • B VK+n
  • C (n+1)VK+n
  • D nVK+n

Step-by-Step Verified Solution

JEE Main 2019 (Online) 9th April Evening Slot Physics - Capacitor Question 111 English Explanation Initially Q = CV(1 + n)

∴ Ceq = (K + n)C

∴ V=CV(1+n)(K+n)C=V(1+n)(K+n)
