1. How can electrons be forced to move?
Energy
Electricity behaves as a water system. It must have pressure to push the water - and a drain to allow it to flow continuously.
KW-H
Electrons can be forced to move by pushing more electrons to the wire. However - no electron can get into the wire unless an equal number of electrons is pushed out of the other end.

2. What is the amount of power used over a period of time?

Watt.

3. What is voltage or electromotive force?
In units of Amperes
