# Graphical Energy Density of a Cylindrical Capacitor

EANDM-HYH1EQ

Figure 1 depicts the cross sectional view of a cylindrical capacitor of length $L = 10.0 \text{ cm}$, inner radius $a$, and outer radius $b$.

Figure 2 shows the energy density of this capacitor as a function of radius $r$, over the range:

$$a \leq r \leq b$$
