MCQ
Effective capacitance between $A$ and $B$ in the figure shown is (all capacitance are in $\mu F$)
- A$21\,\mu F$
- B$23\,\mu F$
- C$\frac{3}{{14}}\mu F$
- ✓$\frac{{14}}{3}\,\mu F$
✓
Answer
Correct option: D.
$\frac{{14}}{3}\,\mu F$
d
(d) Given circuit is balanced Whetstone bridge. So capacitor of $2\ \mu F$ can be dropped from the circuit
${C_{AB}} = 2 + \frac{8}{3} = \frac{{14}}{3}\,\mu F$
