While a capacitor remains connected to a battery and dielectric slab is applied between the plates, then :
1 Potential difference between the plates is changed
2 Charge flows from the battery to the capacitor
3 Electric field between the plates decreases
4 Energy store in the capacitor decreases
Explanation:
When battery is in connection then \(\mathrm{V}=\) constant
\( C^{\prime}=K C, \\ q^{\prime}=k q\)

Capacitance of a parallel plate capacitor becomes \(4 / 3\) times its original value if a dielectric slab of thickness \(t=d / 2\) is inserted between the plates ( \(d\) is the separation between the plates). The dielectric constant of the slab is :
1 8
2 4
3 6
4 2
Explanation:
\( C^{\prime}=\frac{4}{3} C \\ \frac{\varepsilon_0 A}{d-\frac{d}{2}+\frac{d}{2 k}}=\frac{4}{3} \\ K=2\)
