Question

Six capacitors each of capacitance of $2\mu F$ are connected as shown in the figure. The effective capacitance between $A$ and $B$ is

• A. $12\mu F$
• B. $\frac{8}{3}\mu F$
• C. $3\mu F$
• D. $6\mu F$

Answer 1

The correct option is A $12\mu F$

If you carefully see the circuit, A is the common point for all capacitor for one side plate and B is common for other side plate of all capacitor. Thus they are in parallel configuration.

Therefore $C_{AB}=nC=6\times 2=12\mu F$
