HOW DO WE MAKE CURRENTS OF ELECTRICITY?

All conductors contain some movable charges, some movable 'electricity'. We never have to make electricity, since electricity is already there. We just have to move it somehow.

So how can we move it? Just how can we pump the 'electricity' and create some electrical currents?

Brief answer: Create voltage.

Voltage is something like electrical pressure. To make a conductor's charges start moving, just apply some voltage pressure across that conductor.

There are three common ways to create voltages which can push electric charges along:
  - Move a magnet past a conductor.
  - Place two different conductors into some salt water.
  - Touch two different conductors together, then shine some light on them.

This same list describes the three most common kinds of electrical power supply.
