Q. A parallel plate capacitor has a plate separation of $0.01\ mm$ and use a dielectric (whose dielectric strength is $19\ KV/mm$) as an insulator. The maximum potential difference that can be applied to the terminals of the capacitor is
A) $190\ V$
B) $290\ V$
C) $95\ V$
D) $350\ V$
Explanation
(a) Maximum potential difference
$= 19\frac{kV}{mm} \times 0.01mm = 0.19kV = 190V$
