Which energies are stored
Gravitational potential
Chemical
Gravitational potential
What happens if I increase the voltage
The bulb gets brighter
What happens if i add another bulb to a series circuit and why
The bulbs get dimmer because they share the energy
What happens if I add another bulb in a parallel circuit and why
The brightness of the bulbs don’t change because they receive the same amount and don’t have to share
What do a metres measure
The current in a circuit
What is voltage
The amount of energy in a circuit
How do u measure the total energy that is being used
The power rating times the amount of time it is being used for
How do we generate electricity
Fossil fuels
Biomass
Generators
What are three types of energy resources
Fossil fuels
Wind power
Solar power
What is the advantages and disadvantages of fossil fuels
Cheap and large amounts of energy can be generated in a short amount of time
Mining the coal to burn as fossil fuels in dangerous and expensive
What are advantages and disadvantages of solar power
No pollution is created
Doesn’t work at night because there is no sun and is very expensive to build
What are the disadvantages and advantages of wave power
Not expensive to operate and can produce lots of energy
Can be noisy
Few suitable places for it
Doesn’t produce constant amounts of energy
