QJEEM20Phb4d3: JEE Main 2020 Physics - Class 12 JEEM20Phb4d3 Solution: Effective capacitance of parallel combination of two capacitors …
Effective capacitance of parallel combination of two capacitors C1 and C2 is 10 μF. When these capacitors are individually connected to a voltage source of 1V, the energy stored in the capacitor C2 is 4 times that of C1. If these capacitors are connected in series, their effective capacitance will be :
Multiple Choice Options
- A 4.2 μF
- B 8.4 μF
- C 1.6 μF
- D 3.2 μF
