Question

The equivalent capacitance between P and Q of the given figure is (the capacitance of each capacitor is$1\mu F$ ):

• A. $2\mu F$
• B. $0.5\mu F$
• C. $5\mu F$
• D. $0.2\mu F$

Answer 1

Answer: (B)

We know when capacitors are in series:

$\frac{1}{C_{eff}}=\frac{1}{C_1}+\frac{1}{C_2}$
and when in parallel:

$C_{eff}=C_1+C_2$
