Electricity

Front

What is electricity?

Back

Electricity is a form of energy resulting from the flow of electric charge, typically through conductors.

Front

What are conductors?

Back

Conductors are materials that allow electricity to flow through them easily, such as metals like copper and aluminum.

Front

What are insulators?

Back

Insulators are materials that do not allow electricity to flow through them easily, such as rubber, glass, and plastic.

Front

What is radiant energy?

Back

Radiant energy is energy that travels in waves and can be seen as light, such as the light emitted by a lamp.

Front

What is mechanical energy?

Back

Mechanical energy is the energy associated with the motion and position of an object, often used in machines.

Front

How does a lamp transform energy?

Back

A lamp transforms electrical energy into radiant energy (light) and thermal energy (heat).

Front

What is an example of a device that transforms electrical energy into mechanical energy?

Back

A ceiling fan transforms electrical energy into mechanical energy to rotate its blades.

Front

What is an example of a device that does NOT transform electrical energy into mechanical energy?

Back

A flashlight does not transform electrical energy into mechanical energy; it converts it into light.

Front

What happens when electricity flows through a conductor?

Back

When electricity flows through a conductor, it can power devices and create light, heat, or motion.

Front

What is the role of a light bulb in an electrical circuit?

Back

A light bulb transforms electrical energy into radiant energy, providing light.
