Shock Factor
What is static electricity?
A build-up of electric charges (electrons) on an object
What is a conductor?
A material that allows electrons to flow easily
What is the law of conservation of energy?
Energy cannot be created or destroyed, only changed from one form to another.
What are the four main parts of a circuit?
Energy source, conductor, load, switch
What is a power grid?
A network that delivers electricity from power plants to homes and buildings.
What causes static electricity to build up?
The transfer (gain or loss) of electrons
What is an insulator?
A material that prevents the flow of electrons
What type of energy transformation happens in a battery?
Chemical energy → electrical energy
What is a simple circuit?
A complete path that allows electricity to flow.
What are the top three energy sources in Ontario?
What happens when opposite charges interact?
They attract
Name two examples of conductors.
Some examples include: metals, salt water, graphite, and the human body.
What energy transformation occurs when you strum a guitar?
Kinetic energy → sound energy
What is an open circuit?
A circuit where the path is broken and electricity cannot flow.
How is electricity generated?
1. Energy comes from a source (e.g., moving water or wind).
2. That energy spins a generator using a turbine.
3. The generator converts the kinetic energy into electricity.
What happens when like charges interact?
They repel
Name two examples of insulators.
Some examples include: rubber, air, wood, glass, fresh water.
What type of energy does hydroelectric power use to generate electricity?
Kinetic energy of moving water → electrical energy
What is the difference between a series circuit and a parallel circuit?
Series has one path; parallel has multiple paths
What are the four components of a power grid?
1. Generation
2. Transmission
3. Distribution
4. Balancing
What is the difference between static electricity and current electricity?
Static electricity is a build-up of charges in one place, while current electricity is the continuous flow of electrons through a circuit.
Why are metals good conductors?
Their electrons can move freely, allowing electricity to flow easily
What is the difference between renewable and non-renewable energy sources?
Renewable sources can be replenished (e.g., wind, solar), while non-renewable sources are limited and will run out (e.g., fossil fuels).
What happens in a parallel circuit if one bulb breaks? Why?
The other bulbs stay on because electricity can still flow through other paths.
What is the difference between energy efficiency and energy conservation?
Energy efficiency means using technology that does the same job but uses less energy.
Energy conservation means using less energy by changing your behavior.
