Dry air will begin to ionise when the electric field strength reaches about 3 MV/m (i.e. 3 x 106 V/m), resulting in electrical breakdown. This can result in a spark or arc discharge between conductors separated by air. Assume that you have two parallel conducting plates separated by air, with a large distance d between them, and you apply a voltage of V-10000 Volts to the plates, as seen in the Figure A4, and you gradually decrease the distance between the plates, while keeping the voltage constant. How close can you bring these two plates together, before an electrical spark flies from one plate to the other? For the value of the distance d between the plates you found above, calculate the capacitance of the resulting parallel plate capacitor, and the total charge q stored in the capacitor, if the area of the plates is 1m2.
