Answer to Question 1

E

Answer to Question 2

Capacitors are devices that can store electric charge. They store charge for later use, such as in a camera flash, and as energy backup in computers if the power fails. Capacitors can also block surges of charge and energy to protect circuits. Very tiny capacitors serve as memory for the ones and zero of the binary code in the random access memory of computers.
