The equivalent capacitance for the circuit drawn below is
A. 18µf
B. 4uf
C. 2uf
D. 12uf
E. 13uf
ANSWER: Option B
EXPLANATION: To find the equivalent capacitance
For n capacitor series arrangements
1/Ctotal = 1/C1 + 1/C2 + 1/C3 + … + 1/Cn
For n capacitor parallel arrangements
Ctotal = C1 + C2 + C3 + … + Can
Just the opposite of equivalent resistance!
