Question

The charge
on the 4pf capacitor
in the circuit is
​

Answer 1

Answer:

The charge stored in the 4 micro farad capacitor is 24 micro coulomb.

Explanation:

In this case, it is required to find the charge stored in the 4 \mu F4μF . The capacitors 4\ \mu F4 μF and 8\ \mu F8 μF are in series. Their equivalent is given by :

\dfrac{1}{C}=\dfrac{1}{C_1}+\dfrac{1}{C_2}C1=C11+C21

\dfrac{1}{C}=\dfrac{1}{4}+\dfrac{1}{8}C1=41+81

C=2.67\ \mu FC=2.67 μF

Both capacitors are connected in series, and in series combination charge remains constant. It is given by :

q=CVq=CV

q=2.67\times 9q=2.67×9

q=24.03\ \mu Cq=24.03 μC

or

q=24\ \mu Cq=24 μC

So, the charge stored in the 4 micro farad capacitor is 24 micro coulomb.
