How the fuck does electricity works?

How can you transport it with cables and store like a liquid?

One day there was an electron and this electron did not know where to go, so it created an electric field that emanated from itself in all directions. The electric field soon touched everything in the universe, no matter how far it was from the electron. Some stuff was positive, which it liked, so it went in the direction of positivity. Some stuff it did not like, i.e. other electrons with their own electric field, so it went in the opposite direction of negativity. As the little electron moved it figured out that it was only capable of moving in certain places at certain times, when it could "see" its path, or when there was enough activity for it to move.

You put a voltage over a piece of metal and boom you get current. This is an experimental fact. There are a few ways to create this voltage. Moving a magnet around, for example, induces a voltage in the closed loop that encircles the magnet.

Hijacking this thread momentarily.
I have a question, has anyone implemented a tested out an algorithm (not Simulink Model) of DTC scheme for induction machines? I have been trying to do so on MATLAB but I always find out that the voltage of the DC link has to be equal to the line voltage of the machine or the electromagnetic torque will simply not be enough to initiate movement, also on the case it does by having a lower reference signal for the torque, it stops following the reference after a short while. Any help will be immensely appreciated.
