Electrical Fundamentals

The outer shell electron of an atom; can leave the atom more easily than other types of electrons.

• Ions

• Valence electrons

• Static electricity

• None of the above

When an atom is stable

• Nucleus is stable

• Number of protons is equal to number of neutrons

• Number of protons is equal to number of electrons

• Number of electrons is equal to number of neutrons

What is the charge of neutrons

• Neutral

• (+ ve)

• (- ve)

• None of the above

An atom or molecule that has an electrical charge.

• Static electricity

• Ions

• Valence electrons

• Charge

Any substance that has atoms with easily moving electrons is called

• Matter

• Insulator

• Semi conductor

• Conductor

An insulator is

• Materials that allow the electrons to move freely through them

• Materials that allow the electrons to move partially through them

• Materials do not allow the electrons to move freely through them

• None of above

Silicon and Germanium are known as

• Semi conductor

• Insulator

• Conductor

• None of the above

Choose all right answers

• (+ve) and (-ve) charge attract

• (-ve) and (-ve ) charge attract

• (+ve) and (+ve) charge repel

• (+ve) and (+ve) charge attract

Aircraft bonding is done to reduce
