a typical AAA battery has stored energy of about 3400 J. ( batter capacity is typically listed as 625 mA h, meaning that charge can be delivered at approximately 1.5 V.) suppose you want to build a parallel plate capacitor to store this amount of energy, using a plate separation of 3.6 mm and with air filling the space between the plates.

a) assuming tat the potential difference across the capacitor is 1.5 V, what must the area of each plate be ??
A=............*10^... m^2
