Capacitance

Explanation of question 4

Two 20pF capacitors are connected in parallel, and the combination connected in series with a 60pF capacitor. A single equivalent capacitor will have a value of

  1. l00 pF
  2. 86 pF
  3. 70 pF
  4. 24 pF

The answer is :- 4 Equivalent capacitance of parallel combination = 20 + 20 = 40pF. Equivalent capacitance of 40pF in series with 60pF is 24pF
