What causes the electrons to move?

Voltage is the “outside force” that causes electrons to move. Voltage is potential energy. Potential energy has the ability to perform work. An example of potential energy is an axe being held above a piece of wood. If the axe is allowed to drop onto a piece of wood, then the wood would split. Notice the word “if” appears. Potential energy does work ONLY if it is allowed to do so.
