Question

The equivalent capacitance between points A and B is

Answer 1

Question :

The effective capacitance between the points P &B.

Theory :

Combination of Capacitors

1) Series combination

In Series combination, each capacitor has equal charge for any value of capacitances .

⇒Capacitors in series :

For n capacitors connected in series the equivalent capacitance

$\dfrac{1}{c_{eq} } = \dfrac{1}{c_{1} } + \dfrac{1}{c_{2} } + ..... + \dfrac{1}{c_{n} }$

2) Parallel Combination

When capacitors are connected in parallel,the potential difference across each capacitor is same .

⇒Capacitors in Parallel :

For n capacitors connected in parallel, the equivalent capacitance is given by ;

$c_{eq} = c_{1} + c_{2} + .... c_{n}$

Solution :

${\purple{\boxed{\large{\bold{C_{eq}=\dfrac{10}{3}\mu\:F}}}}}$
