Chapter 11, Problem 10RQ

1. 10. One of the 22 named, derived units in the metric system is the volt, which can be expressed as 1 joule per coulomb (V = J/C). A coulomb is the total electric charge on approximately 6.24 x 10¹⁸ electrons. The voltage on a capacitor is given by V = ∆Q/C + V_o volts, where ∆Q is the change in charge (coulombs] stored, V_o is the initial voltage on the capacitor, and C is the capacitance [farads].
   1. a. Create a proper plot of voltage (V, on the ordinate) and total charge (∆Q) for a 5-farad capacitor with an initial voltage of 5 volts for 0 <∆Q <20.
   2. b. Using the graph, determine the total energy stored in the capacitor for an addition of 15 coulombs.
