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?
Energy
1000 watts
In a wire conductor - there are billions of loose or free electrons - all safely in place in their fields. They're distributed evenly throughout the wire.
Watt.
3. What is voltage or electromotive force?
In units of Amperes
Voltage or electromotive force is pressure required to force electrons into a wire. Voltage is also measured in units called Volts.
From an electricians - pov - electricity is the movement of electrons. Electrons are atomic particles found in every substance. An electron has one main characteristic which is a negative electrical charge.

4. How is current measured?
The design that the system is able to handle total amperage needs.

5. What is the basic unit to measure electrical power?
In units of Amperes
Voltage and current in a circuit. That is - voltage(in volts) times current (in amperes) equals power (in watts) P=E x I

6. What is a useful characteristic that can be used in an appliance?
The design that the system is able to handle total amperage needs.
When current flows - the resulting work is energy. Current flow tends to heat whatever its moving through - which is a useful characteristic of an appliance.
Stands for direct current and it is when electrons move in one direction.
