Question

What is the equivalent capacitance between $A$ and $B$ in the diagram below?

• A. $10F$
• B. $5F$
• C. $2.5F$
• D. $0F$

Answer 1

Answer: (C)

$2.5F$

The equivalent capacitance of the two capacitors connected in parallel=$3\mu F+2\mu F=5\mu F$

This combination is in series with $5\mu F$ capacitor.

Hence final equivalent capacitance=$\frac{5\times 5}{5+5}F=2.5F$
