Question

The parallel combination of two air filled parallel plate capacitors of capacitance C and nC is connected to a battery of voltage, V. When the capacitors are fully charged, the battery is removed and after that a dielectric material of dielectric constant K is placed between the two plates of the first capacitor. The new potential difference of the combined system is :

Select the correct option:

A

$\frac{(\mathrm{n}+1) \mathrm{V}}{(\mathrm{K}+\mathrm{n})}$

B

$\frac{V}{K+n}$

C

V

D

$\frac{\mathrm{nV}}{\mathrm{K}+\mathrm{n}}$

✓ Correct! Well done.
