NEETPhysicsCapacitorMCQ+4 / −1
Three capacitors each of capacitance C and of breakdown voltage V are joined in series. The capacitance and breakdown voltages of the combination will be
  1. A
    3C,V33C,{V \over 3}3C,3V​
  2. B
    C3,3V{C \over 3},3V3C​,3V
  3. C
    3C,3V3C,3V3C,3V
  4. D
    C3,V3{C \over 3},{V \over 3}3C​,3V​

Correct answer: B

In series combination of capacitors
Veff = V + V + V = 3V

1Ceff=1C+1C+1C{1 \over {{C_{eff}}}} = {1 \over C} + {1 \over C} + {1 \over C}Ceff​1​=C1​+C1​+C1​

⇒Ceff=C3 \Rightarrow {C_{eff}} = {C \over 3}⇒Ceff​=3C​

Thus, the capacitance and breakdown voltage of the combination will be C3{C \over 3}3C​ and 3V.
