Concepts Of Physics MCQ Edition [Volume 2]PhysicsCapacitors
Three capacitors, each possessing a capacitance of 6 F , are provided. The minimum and maximum capacitances that can be formed are
Options
- A3 F , 12 F
- B6 F , 18 F
- C2 F , 12 F
- D2 F , 18 F
Correct answer
D. 2 F , 18 F
Step-by-step solution
For minimum capacitance, all three capacitors must be connected in series. 1 C_ min = 1 C + 1 C + 1 C 1 C_ min = 1 6 + 1 6 + 1 6 = 3 6 = 1 2 C_ min = 2 F For maximum capacitance, all three capacitors must be connected in parallel. C_ max = C + C + C C_ max = 6 + 6 + 6 = 18 F The minimum and maximum capacitances are 2 F and 18 F respectively.
