QJEEM20Ph3922: JEE Main 2020 Physics - Class 12 JEEM20Ph3922 Solution: Two identical capacitors A and B, charged to the same potential …

Two identical capacitors A and B, charged to the same potential 5V are connected in two different circuits as shown below at time t = 0. If the charge on capacitors A and B at time t = CR is QA and QB respectively, then (Here e is the base of natural logarithm) JEE Main 2020 (Online) 9th January Evening Slot Physics - Semiconductor Question 141 English

Multiple Choice Options

  • A QA = CVe, QB = VC2
  • B QA = CV2, QB = VCe
  • C QA = VC, QB = VCe
  • D QA = VC, QB = CV

Step-by-Step Verified Solution

In case I diode is reverse biased

QA = CV

In case II, current will flow as diode is forward biased.

QA = CVe
