Electrical Splices & Electron Theory

What is electricity often described as?

• A flow of water in a pipe.

• A flow of electrons.

• A type of heat.

• A magnetic field only.

What is the smallest part into which an element can be divided?

• A molecule.

• An atom.

• A nucleus.

• An electron.

Which part of an atom has a negative electrical charge?

• Nucleus

• Proton

• Electron

• Neutron

The center part of an atom that contains positively charged particles is called the:

• Electron

• Nucleus

• Proton

• Orbit

What is the name for the attraction between the positive nucleus and the negative electron in an atom?

• Magnetic Force

• Gravity

• Electrostatic Force

• Cohesive Force

When an atom has an equal number of electrons and protons, it is said to be:

• Positively charged.

• Negatively charged.

• Electrically neutral.

• An ion.

Which particle found inside the nucleus has no electrical charge?

• Electron

• Proton

• Neutron

• Ion

What is the First Law of Electrostatics about charges?

• Like charges attract each other.

• Unlike charges attract each other, and like charges repel each other.

• All charges attract each other.

• All charges repel each other.

Materials that have many "free electrons" and allow electricity to flow easily are called:

• Insulators

• Conductors

• Semiconductors

• Non-conductors

Which type of electricity is produced when two objects are rubbed together, like rubbing a rubber rod with wool, and the charges are "fixed" or "at rest"?

• Dynamic Electricity

• Current Electricity

• Static Electricity

• Permanent Electricity
