Simple circuits
What is electricity?
The flow of electrons through a circuit.
What is the main difference between series and parallel circuits?
A series circuit has one path for electricity to flow, whereas a parallel circuit has multiple pathways.
What is energy transfer?
Energy is transferred from one object to another.
What unit of measurement is voltage measured in?
Volts
What is renewable energy?
Energy from natural sources that can be reused
What are the 3 main components of a circuit?
Power source, load and conductor.
In a series circuit, what happens to the brightness of the bulbs if you add more?
They begin to dull and lose their brightness.
What is energy transformation?
Energy changes from one form to another
What units of measurement is current measured in?
Amps (A)
What is non-renewable energy?
Energy that cannot be replaced or reused.
What is the difference between a conductor and an insulator?
Conductors allow energy to pass through, while insulators do not.
In a parallel circuit, what happens to the bulbs if you add more?
The bulbs share the power and have the same brightness.
Transfer
What unit of measurement is resistance measured in?
Ohms
What is an example of renewable energy?
Wind, solar, hydro, etc.
What happens to the flow of electricity in a circuit if a wire is cut?
The bulb will turn off
In a parallel circuit, what happens if I take out one of the light bulbs?
The rest will stay on
The chemical energy from food turns into mechanical energy when you ride a bike. Is this an example of energy transfer or energy transformation?
Transformation
What is the law that explains the relationship between voltage, current and resistance?
Ohm's Law
What is an example of non-renewable energy?
coal, natural gas, oil, and nuclear energy
Draw a simple circuit, showing 2 bulbs, a battery and a switch.
Correctly draws a simple circuit showing 2 bulbs, a battery and a switch.
Which type of circuit would you see in your house and why?
Parallel circuits are used within houses as it allows multiple lights to be on while others can turn off.
Provide an example of both an energy transfer and an energy transformation
Examples will vary
What is the relationship between voltage, current, and resistance in a circuit?
They are all mathematically related and influence each other.
Which source of energy is more harmful to the environment and why?
Non-renewable. It causes fumes and pollution to the environment. Also results in land degradation and habitat destruction.
