Question 258: Electrostatics & Capacitance

Question

A parallel plate capacitor with plate area A and plate separation d = 2 m has a capacitance of 4 $$\mu$$F. The new capacitance of the system if half of the space between them is filled with a dielectric material of dielectric constant K = 3 (as shown in figure) will be :

Accepted Answer

Equivalent circuit is
Now, $${{{\varepsilon _0}A} \over d} = 4\,\mu F$$
$$ \Rightarrow {{12} \over 8}{{{\varepsilon _0}A} \over d} = 6\,\mu F$$

Answer

2$$\mu$$F

Answer

32$$\mu$$F

Answer

6$$\mu$$F

Answer

8$$\mu$$F
