Which is an example of a transformation of electrical energy to mechanical energy?

• ​ceiling fan spinning​

• 1. lightbulb warming up

• 1. heater feeling warm​

• 1. bell making noise​

What is the function of the lightbulb in this simple circuit?

• provides a source of energy

• transforms electrical energy to radiant energy

• allows the flow of negative particles

What is the function of the battery in this simple circuit?

• provides a source of energy

• transforms electrical energy to radiant energy

• allows the flow of negative particles

The flow of energy as a current is called ________________.

• electricity

• heat

• light

• sound

Metals, like copper wire, allow electrical energy to move through, and are examples of -

• Static Electricity
• Insulators
• Conductors
• Electromagnets

A material that does not allow electricity to flow through it is called a(n) -- 

• insulator

• conductor

• dry cell

• circuit

According to this list, what is the student most likely investigating?

• how circuits work

• types of conductors

• insulating materials

• charged particles
