How does electricity get stored ? How does it move down a cable? And will I slow it down if the cable is curved or bent (the way water will in a hose)

Electricity gets stored in other forms of energy. For example, a battery consists of two materials, one that that is given a lot of electrons (negative ion), and one that either had its electrons taken away (positive ion), or that is electrically neural and is able to receive a lot of electrons. When the two materials are connected, energy is transferred through the connecting wire from the negative ionic material (positive terminal) to the other terminal (typically considered a ground). This is an example of DC power
Hydroelectric dams convert energy stored in the motion of water into electricity by using waters to spin massive magnets. Oscillating (moving back and forth) magnetic fields generate electron motion in nearby conductors like wires. This is an example of AC power.
Electricity is transferred by electron motion. Electrons move relatively slowly down a wire, but their jostling and bumping as they move sends a stream of energy through the wire (think of like a continuous domino effect).
If you restrict the cross section area of a wire of a wire (pinching or shaving a bit off), it will increase the resistance by various amounts.
