JEE Advanced2012PhysicsCapacitanceActual
In the given circuit, a charge of +80 C is given to the upper plate of the 4 F capacitor. Then in the steady state, the charge on the upper plate of the 3 F capacitor is
Options
- A+32 C
- B+40 C
- C+48 C
- D+80 C
Correct answer
C. +48 C
Step-by-step solution
The total charge on plate A will be 80 C . 2 F and 3 F capacitors are in parallel. Therefore, C_ e q =2+3=5 HF Charge on capacitor of 3 F capacitance q= 3 5 80=48 C
