, it is obvious that the term "charge" is the direct neighbour of term "capacitor", hence, the dependency relation path length d r_path_l en equals to 1 as shown in Figure 1(b) (1).
"charge" is a bit farther away from the term "farad" as the d r_path_l en between term "charge" and "farad" equals to 2 as shown in Figure 1(b) (3).
