Question : 106 of 200

Marks: +1, -0

Two condensers of capacity 2F and 3F are connected in series, a third condenser of 1F is connected in parallel to them, the resultant capacity in Farad (F) will be :

6 /F
5 /11F
5 / 6F
11 /5F

Validate

Solution:

Two capacitor of capacity 2F & 3F connected in series

C_\eq={C_1×C_2}/{C_1+C_2}={2F×3F}/{2F+3F}=6/5F

Series connected capacitor, connected with capacitor with parallel

C_\eql= C _\eq+ C _3

C_\eql=6/5+1F
