Unit 4 and 5: Energy Review

Front

What is a conductor of electricity?

Back

A conductor of electricity is a material that allows electric current to flow through it easily. Examples include metals like copper and aluminum.

Front

Which material is the best conductor of electricity?

Back

Copper is the best conductor of electricity among common materials.

Front

What happens in a series circuit when one lightbulb burns out?

Back

In a series circuit, if one lightbulb burns out, it breaks the circuit and all the other lightbulbs will not light.

Front

What happens in a parallel circuit when one lightbulb burns out?

Back

In a parallel circuit, if one lightbulb burns out, the other lightbulbs will still light because each lightbulb has its own path to the power source.

Front

What is light reflection?

Back

Light reflection is when light bounces off a surface. For example, a mirror reflects light.

Front

What is light refraction?

Back

Light refraction is the bending of light as it passes from one medium to another, like from air into water.

Front

What does it mean if an object appears orange?

Back

If an object appears orange, it means that it reflects orange light and absorbs all other colors of light.

Front

What is the role of a light source in a circuit?

Back

A light source, like a lightbulb, converts electrical energy into light energy.

Front

What is an insulator?

Back

An insulator is a material that does not allow electric current to flow through it easily. Examples include rubber and glass.

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, all components are connected in a single path, while in a parallel circuit, components are connected across multiple paths.
