G8 U8 Electricity and Magnetism Correctives

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which the components are connected end-to-end, so that the current flows through each component in turn.

Front

What is an insulator?

Back

An insulator is a material that does not allow electrons to flow easily, preventing the flow of electric current.

Front

What is a conductor?

Back

A conductor is a material that allows electrons to flow easily, enabling the flow of electric current.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. It can be turned on and off.

Front

What is the advantage of using electromagnets?

Back

Electromagnets can be turned on and off, allowing for control over their magnetic field.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit in which the components are connected across common points or junctions, allowing multiple paths for the current.

Front

What is the role of a switch in a circuit?

Back

A switch is a device that can open or close a circuit, controlling the flow of electricity.

Front

What is the energy source in a circuit?

Back

The energy source in a circuit provides the electrical energy needed for the current to flow, such as a battery or power supply.

Front

What happens when a circuit is open?

Back

When a circuit is open, the flow of electricity is interrupted, and the devices in the circuit do not operate.

Front

What happens when a circuit is closed?

Back

When a circuit is closed, the flow of electricity is complete, allowing devices in the circuit to operate.
