electric discharge resulting from the accumulation of electric charge on an insulated material: _____________.

• positive charge

• static electricity

What is electricity?

• The flow of protons

• The flow of neutrons

• The flow of electrons

• The movement of the nucleus

Answer explanation

Electricity is defined as the flow of electrons, which are negatively charged particles. This flow creates electric current, essential for powering devices and systems.

What is the flow of electric charge, often through wires, called?

• Attract

• Repel

• Electricity

• Neutral

Answer explanation

The flow of electric charge through wires is known as electricity. It is the movement of electrons that creates an electric current, making 'Electricity' the correct answer.

Electricity that flows constantly in one direction on a given path.

• current electricity

• static electricity

• electron pathway

• conductor

What is a complete pathway for electric current called?

• Insulator

• Circuit

• Conductor

• Nucleus

Answer explanation

A complete pathway for electric current is called a circuit. It allows electrons to flow from a power source, through conductors, and back, enabling electrical devices to function. Insulators and conductors refer to materials, not pathways.

Match the following descriptions with the correct concept of electricity.

• Magnetic field is an example of?

• The flow of electric charge

• Electric current refers to?

• The force that pushes objects with the same charge apart

• Atomic structure stability is due to?

• A type of magnetism

• Electrostatic repulsion is?

• The balance between protons and neutrons

If two objects have the same electric charge, they will (a)  

• Repel each other

• Attract each other

• Become neutral

• Lose their charges

Answer explanation

When two objects have the same electric charge, they will repel each other due to the principle that like charges repel. This is a fundamental concept in electrostatics.

What does an electric circuit need to work properly?

• An incomplete pathway

• Only insulators

• A complete pathway

• Only a battery

Answer explanation

An electric circuit requires a complete pathway for current to flow. Without a complete pathway, the circuit cannot function, making 'A complete pathway' the correct choice.

What are materials called that allow electric current to flow easily?

• Insulators

• Conductors

• Circuits

• Protons

Answer explanation

Materials that allow electric current to flow easily are called conductors. They have free electrons that facilitate the movement of electricity, unlike insulators, which resist current flow.
