Very pretty, but looks overly complicated to me.
Just remember that E = IxR and P = IxE.
All the rest you can work out in a few seconds!

It is hardly complicated.

It is a learning tool for basic electronics students. Such
students
aren't immediately aware of all the transpositions.


One of those silly tricks I learned (from Popular
Electronics?) for Ohm's Law, before I understood
transposition:

E=eagle I=Indian R=rabbit

[R]abbit sees the eagle above the indian R=E/I

[i]ndian sees the eagle above the rabbit I=E/R

[E]agle sees the indian beside the rabbit E=IR
