Question: What is the fundamental rule at the base of all electrical phenomena?

Answer: The fundamental rule at the base of all electrical phenomena is that like charges repel and opposite charges attract.

Question: What causes an object to become electrically charged?

Answer: An object that has unequal numbers of electrons and protons is electrically charged.

Question: What does Coulomb’s Law state?

Answer: For charged particles or objects that are small compared with the distance between the charges varies directly as the products of the charges and inversely at the square of the distance between them.

Question: What is the difference between a good conductor and a good insulator?

Answer: Electrons move easily in good conductors and poorly in good insulators.

Question: What are two ways electric charge can be transferred?

Answer: Two ways electric charge can be transferred are by friction and by contact.

Question: What happens when a charged object is placed near a conducting surface?

Answer: Electrons will move in a conducting surface.

Question: What happens when an insulator is in the presence of a charged object?

Answer: Charge polarization can occur in insulators that are near a charged object.
