Find the minimum and maximum capacitance obtained from three capacitors of $6 \ \mu F$ each.

Three capacitors are connected to a $D.C.$ source of $100 \; V$ as shown in the figure. If the charges accumulated on plates $a, b, c, d, e,$ and $f$ are ${q_a}, {q_b}, {q_c}, {q_d}, {q_e},$ and ${q_f}$ respectively,then:

In the circuit shown,a potential difference of $30\, V$ is applied across $AB$. The potential difference between the points $M$ and $N$ is....$V$

Write the difference between capacitors in series and parallel connections.

Two capacitors of $1\,\mu F$ and $2\,\mu F$ are connected in series. The resultant capacitance will be ..... $\mu F$.

Three parallel plate air capacitors are connected in parallel. Each capacitor has plate area $A/3$ and separation between the plates is $d$, $2d$, and $3d$ respectively. The equivalent capacity of the combination is ($\epsilon_0$ is the permittivity of free space).
