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 [AMU (Engg.) 1999]
A) 190 V
B) 290 V
C) 95 V
D) 350 V
Correct Answer:
A
Solution :
Maximum potential difference \[=19\frac{kV}{mm}\times 0.01mm=0.19kV=190V\]
