Two capacitors c1 and c2 are connected in a circuit as shown in figur the pd va-vb is

Answer 1

where is the figure...??

Answer 2

Answer:

The correct answer to this question is $8V$

Explanation:

Given - Two capacitors c1 and c2 are connected in a circuit.

To Find - Find the pd va-vb is

Now, applying Kirchhoff's voltage law is,

Kirchhoff's voltage law says that for every closed network, the voltage around a loop equals the total of all voltage drops in the same loop and equals zero.

$24 - \frac{q}{2} - 12 - \frac{q}{4} =0$

$12 - (\frac{2q+q)}{4} = 0\\\frac{3q}{4} = 12$

$q = 16$

$V_{AB} = \frac{-q}{C} = \frac{-16}{2} \\= 8V$
