Circuits
What are two ways can you increase the voltage running through a circuit?
Increase the battery voltage
Shorten the wires
Increase the diameter of the wire
Decrease the diameter of an insulator
What does it mean if something repels something else?Give an example.
The objects move away from one another.
South pole - South pole
Which will create a larger electrical current in a circuit:
Moving a magnet fast or slow in and out of the circuit.
Fast
What are the required parts to include to make a successful circuit?
A power source (battery), wires (electric current), and lightbulb or object doing work (load)
Which is a stronger magnet: a nail that picks up 3 paper clips or 8 paper clips?
8 paper clips
True or false: increasing the coils of wire around an object will result in the object having a stronger magnetic field.
True
If you reverse the current in a circuit, and that is the only thing you change, does the amount of voltage change at all?
NO!
What does the law of attraction state?
Opposites will attract (N and S pole with come together)
True or false: As long as a circuit is open, there is a magnetic field running through it.
False: must be closed because this will cause the electricity to run through the circuit.
What are some other ways that electricity can be conducted other than the traditional way, the circuit.
Salt water
Solar energy
Wind energy
In order for an object to be a magnet, how must the poles be aligned?
They all need to be facing in the same direction.
How is a magnetic field bad??
Health risks. Tumors and cancers. Stunted growth. Etc.
