Another problem to while away a rainy Sunday afternoon would be to replace each of the resistors in the cube of subsection 4.14.1 with capacitors each of capacitance $c$ . What is the total capacitance across opposite corners of the cube? I would start by supposing that the cube holds a net charge of $6Q$ , and I would then ask myself what is the charge held in each of the individual capacitors. And I would then follow the potential drop from one corner of the cube to the opposite corner. I make the answer for the effective capacitance of the entire cube 1.2 $c$ .
