### Explanation of question 6

In Fig. 12.3, the capacitance between A and B is

The answer is :- 3 Basically the circuit shown above is two 6µF capacitors in series, connected in parallel with a 4µF capacitor. The two 6µF capacitors have an equivalent capacitance of 3µF, giving an overall circuit capacitance of 7µF.
