Modern computer memories use parallel-plate capacitors to store information, and these capacitors are the basic elements of a random-access memory (RAM) chip. Assume one of these capacitors has plates with an area of L xL, where L =1.0 µm (=1.0 ×10-6 m), and a plate separation of d =10 nm (=1.0 ×10-8 m). (a) Find the capacitance of such a capacitor. (b) Calculate the amount of charge that must be placed onto the plates to obtain a potential difference of 5.0 V across the plates. (c) How many electrons does this charge correspond to?
