This type of energy transfer warms the top of lakes.
What is radiation
100
This is a continuous flow of electric charge through a pathway.
What is electric current?
100
This is how we produce electrical energy.

100
This carries electric charges well.
What is conductor?
200
This is what happens when you trip a circuit breaker.
What is it opens an electric current?
200
This type of energy are both visible light and radio waves.
What is electromagnetic energy?
200
Where energy can travel through conductors in a complete path.
What is a closed circuit?
200
This kind of mechanical energy is stored in 6 voltage batteries.
What is chemical energy?
200
A disconnected wire halts the flow of electricity in this.
What is a open circuit?
300
When insulators, such as wood or air, block a path the circuit is called this.
What is an open circuit?

This might happen to your home if the step down transformer (from the plant to your home) didn't work correctly ?
What is electricity at a too high voltage may reach the home and result in burning out electrical appliances and start fires?
300
The electric force between two charges that are not moving is this.
What is static electricity?
300
For every action there is an equal and opposite reaction.
What is Newton's Third Law?
300
Electric energy travels to devices along a single path in this.
What is a series circuit?
400
You should never use this while you are watering the lawn.
