Current Question (ID: 16553)

Question:

$\text{The equivalent capacitance between points } a \text{ and } b \text{ in the network shown below is:}$

Options:

1. $5 \text{ C}$
2. $4 \text{ C}$
3. $3 \text{ C}$
4. $2 \text{ C}$

Solution:

$\text{The capacitors are arranged in a combination of series and parallel.}$ $\text{The two capacitors in series at the top and bottom each have an equivalent capacitance of } \frac{C}{2}. $ $\text{These are in parallel with the middle capacitor, giving:}$ $C_{eq} = \frac{C}{2} + C + \frac{C}{2} = 2C. $
