Three identical capacitors are connected in parallel. When this parallel assembly of capacitors is connected to a 12 volt battery, a total of 3.1 x 10-5 coulombs flows through the battery. What is the capacitance of one individual capacitor? (Give your answer as the number of Farads.)
Suppose you construct your own capacitor by placing two parallel plates at a distance 0.27 meters apart. The plates each have a surface area of 0.64 square meters. What is the capacitance of this setup? (Give your answer as the number of Farads.)
Draw a diagram with the new arrows. No they do not point all towards the center.
