Question

A capacitor with air as the dielectric is charged to a potential of $100\mspace{6mu} volts$. If the space between the plates is now filled with a dielectric of dielectric constant 10, the potential difference between the plates will be

• A. 1000 $volts$
• B. 100 $volts$
• C. 10 $volts$
• D. Zero

Answer 1

Answer: (C)

10 $volts$

Answer 2

New potential difference

$= \frac{V}{K} = \frac{100}{10} = 10V$
