1. What voltage are common electrical devices - designed to operate as?
In units of Amperes
120/240 V service.
Stands for direct current and it is when electrons move in one direction.
Most common electrical devices are set to operate as 120/240 V.
2. What is electricity really?
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 alternating current and it is when electrons move in both directions.
The basic unit used to measure electrical power.
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.
3. What is the measurement unit of electron movement
Hertz - one cycle per second is equal to one hertz. Electricity is caused to flow through wires at a frequency of 60 cycles per second. This means electrons flow one direction - then in the reverse direction - repeating this cycle 60 times every seco

Stands for alternating current and it is when electrons move in both directions.
Voltage or electromotive force is pressure required to force electrons into a wire. Voltage is also measured in units called Volts.
4. What does P = E x I stand for?
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.
Watt.

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.
The electrical current flow or amperage - the rate of electron flow that passes through a cross section of wire.

7. What is DC?
60 cycles per second.
Stands for direct current and it is when electrons move in one direction.
The basic unit used to measure electrical power.
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.
8. What is going on in a wire conductor with free electrons?
9. What is a useful characteristic that can be used in an appliance?
The design that the system is able to handle total amperage needs.
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.
