Question

a capacitor of 4 micro farad are connected in series with parallel combination of two capacitors of 6 micro farad each.The equivalent capacitance is ?

Answer 1

Capacitors combine oppositely from resistors

in parallel; C = C1 + C2

in series

Answer 2

1/C = 1/C1 + 1/C2

so., combine the capacitors that are in parallel,
then combine this result [C'] with the one in series,
using the rules above.

Answer 3
