Electrostatic Potential and Capacitance

  1. Three capacitors each of capacitance C and of breakdown voltage V are joined in series. The capacitance and breakdown voltage of the combination will be
    1. 3C,
      V
      3
    2. C
      3V
      3
    3. ​3C, 3V
    4. C
      ,
      V
      33
Correct Option: B

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

Thus, the capacitance and breakdown voltage of the combination will be C/3 and 3V.
