AP EAMCET · PHYSICS · Capacitance
Three parallel plate capacitors of capacitances \(4 \mu \mathrm{~F}\), \(6 \mu \mathrm{~F}\) and \(12 \mu \mathrm{~F}\) are first connected in series and then in parallel. The ratio of the effective capacitances in the two cases is
- A \(1: 11\)
- B \(5: 8\)
- C \(3: 7\)
- D \(4: 9\)
Answer & Solution
Correct Answer
(A) \(1: 11\)
Step-by-step Solution
Detailed explanation
For parallel combination of capacitors, \(C_p=C_1+C_2+C_3=4+6+12=22 \mu \mathrm{~F}\) For series combination of capacitors,…
