PS 06.1 TB Electric Charge

What are the two types of electric charges?

• Positive and Neutral

• Positive and Negative

• Negative and Neutral

• Static and Dynamic

Answer explanation

The two types of electric charges are positive and negative. Positive charges repel other positive charges and attract negative charges, while negative charges do the opposite. Neutral is not a type of charge.

What is the term for materials that allow electric charge to flow easily?

• Insulators

• Conductors

• Resistors

• Capacitors

Answer explanation

The term for materials that allow electric charge to flow easily is 'Conductors'. Unlike insulators, which resist electric flow, conductors facilitate it, making them essential in electrical circuits.

What is the term for electricity that is at rest and not flowing?

• Electric field

• Static electricity

• Conductor

• Electroscope

Answer explanation

The term for electricity that is at rest and not flowing is 'static electricity'. It refers to the buildup of electric charge on the surface of objects, unlike an electric field which describes the force around charged objects.

Which law states that the total charge in an isolated system remains constant?

• Law of conservation of charge

• Electric field law

• Induction principle

• Charging by contact

Answer explanation

The law of conservation of charge states that the total electric charge in an isolated system remains constant over time. This principle is fundamental in understanding electric interactions, making it the correct choice.

What is a material called that allows electric charge to flow through it easily?

• Insulator

• Conductor

• Electroscope

• Static electricity

Answer explanation

A material that allows electric charge to flow through it easily is called a conductor. Conductors, like metals, have free electrons that facilitate the movement of electric charge, unlike insulators which resist this flow.

What is the process of transferring charge by touching or rubbing called?

• Charging by induction

• Charging by contact

• Law of conservation of charge

• Electric field

Answer explanation

The process of transferring charge by touching or rubbing is called charging by contact. This occurs when two objects come into direct contact, allowing electrons to move from one to the other.

What are the three main components of an atom?

• Protons, neutrons, and electrons

• Protons, ions, and molecules

• Neutrons, ions, and molecules

• Electrons, ions, and atoms

Answer explanation

The three main components of an atom are protons, neutrons, and electrons. Protons and neutrons reside in the nucleus, while electrons orbit around it, making this choice the correct answer.

Which subatomic particle is positively charged?

• Neutron

• Electron

• Proton

• Atom

Answer explanation

The proton is the subatomic particle that carries a positive charge, while neutrons are neutral and electrons are negatively charged. Therefore, the correct answer is the proton.

What is the charge of an electron?

• Positive

• Negative

• Neutral

• No charge

Answer explanation

The charge of an electron is negative, which is fundamental to its role in electricity and chemistry. Electrons carry a charge that is equal in magnitude but opposite in sign to that of protons, which are positive.

What is the electrical charge of a neutron?

• Positive

• Negative

• Neutral

• Variable

Answer explanation

A neutron has no electrical charge, making it neutral. This distinguishes it from protons, which are positively charged, and electrons, which are negatively charged.
