Analog and Digital Technology
These technologies use two options such as on/off or 1s and 0s to represent information.
What are digital technologies.
The relationship between force, electric charge, and distance.
What is coulomb's law.
All magnets have two of these, often labeled "south" and "north".
What is a magnetic pole?
The presence or absence of electric current can be use to represent this type of information.
What is binary?
These technologies use continuously varying signals to transfer information.
What are analog technologies.
A circuit component that provides a path for electrons to travel through.
What is a conductor?
Earth's magnetic field points toward its core at this location.
What is the south pole?
This piece of technology can transform a continuous electrical signal to a continuous audible signal.
What are headphones?
A clock uses this as an analogy for the passage of time.
What is the position of the hands.
The construct that represents the magnitude and direction a force would be applied on a positive test charge, if the charge were present.
What is an electric field.
The source of a magnetic field, whether in a bar magnet or a coil of wire.
What is moving charge?
These two variables have the greatest effect on the induced current through a single wire loop.
What is distance and speed?
What are bits.
What is a series circuit?
In temporary magnets, these can align to produce a net magnetic field.
What are domains?
The general term for the relationship between number of loops of wire in a coil and the induced current.
What is a direct relationship?
A revolutionary type of "switch" that has no moving parts and can flip between the on and off state 10s of thousands of times per second.
The method for passing electrons through a wire in which electrons will periodically reverse their direction.
What is alternating current?
The strength of the magnetic field perpendicular to a surface.
What is magnetic flux?
This can produce a rapidly alternating magnetic field in a coil of wire.
What is alternating current?
