A capacitor with air as the dielectric is charged to a potential of \[100\ volts\]. If the space between the plates is now filled with a dielectric of dielectric constant 10, the potential difference between the plates will be [MP PET 1992]
A) 1000\[volts\]
B) 100 \[volts\]
C) 10 \[volts\]
D) Zero
Correct Answer:
C
Solution :
New potential difference \[=\frac{V}{K}=\frac{100}{10}=10V\]
