Question
What is the equivalent capacitance between $A$ and $B$ in the given figure (all are in farad)
✓
Answer
(d) The given circuit can be simplified as follows
Hence equivalent capacitance between $A$ and $B$
$\frac{1}{{{C_{AB}}}} = \frac{1}{{12}} + \frac{1}{{20/3}} + \frac{1}{{16}}$ $==>$ ${C_{AB}} = \frac{{240}}{{71}}\,F$
Hence equivalent capacitance between $A$ and $B$
$\frac{1}{{{C_{AB}}}} = \frac{1}{{12}} + \frac{1}{{20/3}} + \frac{1}{{16}}$ $==>$ ${C_{AB}} = \frac{{240}}{{71}}\,F$

In electromagnetic theory, the electric and magnetic phenomena are related to each other. Therefore, the dimensions of electric and magnetic quantities must also be related to each other. In the questions below, $[E]$ and $[B]$ stand for dimensions of electric and magnetic fields respectively, while $\left[\varepsilon_0\right]$ and $\left[\mu_0\right]$ stand for dimensions of the permittivity and permeability of free space respectively. $[L]$ and $[T]$ are dimensions of length and time respectively. All the quantities are given in $SI$ units.
