Electricity 1
Materials that allow electricity to move through it easily
Conductor
Materials that do not allow electricity to move through them easily
Insulator
What is the purpose of a switch
To switch the circuit from open to closed
The flow of electrons is called
current
How we control electrical currents and navigate them is by using
Circuits
Plastic, glass, and rubber are good examples of
Insulators
Battery, solar cell, generator
This circuit has one pathway
Series
Copper, silver, water, and even the human body are examples of:
conductors
This circuit has more than 1 pathway
Parallel
In this circuit, if one lightbulb goes out, the others will too
Series
What is the difference between an open circuit and a closed circuit
Closed - electrons can flow and circuit is working
Open - electrons cannot flow and circuit is not working
Parallel
Which is a conductive material:
glass wood oil gold
gold
What is responsible for slowing the flow of electrons in a circuit?
any resistors in the circuit
In a series circuit, what will happen to the brightness of the lightbulbs if another lightbulb is added?
They will get dimmer
In series circuit, what will happen to the brightness of bulbs if one of lightbulbs was removed?
They will become brighter
Why is it in a series circuit, the more lightbulbs added the dimmer the bulbs get?
Because adding in more lightbulbs adds more resistance
This type of energy generation is non-renewable
Burning Fossil Fuels/Nuclear Energy
In a parallel circuit, what will happen to the brightness of the bulbs if either a lightbulb was removed or added in?
They will stay the same
From the battery to the buzzer in a circuit, energy is transformed from ____energy to ____energy:
chemical energy to electric energy
Name 3 sources of renewable energy which are used to generate electricity in Canada:
biomass, wind, solar (sun)
When the electricity reaches the filament inside the lightbulb, what is that energy transformed into?
Heat Energy
Light Energy
To conduct a lemon battery experiment, what 2 items are inserted into a lemon to create a chemical reaction?
copper wire and a galvanized nail
This happens to resistance in a circuit as the length of the wire increases
The resistance increases
