Question a typical capacitor in a laptop computer or mp3, Ask an Expert

Academics

Question: A typical capacitor in a laptop computer or MP3 player has a capacitance of around 1 nF (= 1.00 x 10^-9 F). Assume it is a parallel-plate capacitor with plate area A = 3.0 cm² using mica as the dielectric. Now suppose that the mica has been removed and there is air between the plates.

Part A: What is the maximum safe operating voltage of this capacitor? That is, what is the voltage at which there will be dielectric breakdown?

I need the answer and steps thanks!
