Whose Law is it Anyway?
This person's Law allows us to determine the electric field of an extended object using electric flux.
Who is Gauss?
Although his experiments with kites and thunderstorms are NOT how electricity was discovered, this man did play a key role in showing that electricity can be stored in materials.
Who is Benjamin Franklin?
Current flows from positive to negative while electrons move the other way. Either way, electricity will always follow this easiest path to go through.
What is the path of least resistance?
Cutting a magnet in half will result in two smaller magnets being formed. This is because magnetic fields are always this, having a north AND south instead of positive OR negative
What is a dipole?
This property of an electromagnetic wave can be described as the distance between the peak of one wave and the peak of the next. This property is the difference between visible light and ultraviolet.
What is wavelength?
Current, voltage, and resistance. This person's law says that if you know two of them, you can find the other. O yeah, the resistance unit is also named after them.
Who is Ohm?
The universe is full of protons and electrons, positive and negative particles responsible for electric charge, but the net charge of the universe seeming has always been and will always be this number.
What is 0?
These objects work by getting a material so cold that their super organized atom structures create no resistance for electrons moving through.
What are superconductors?
Unlike a paramagnetic paperclip, a fridge magnet that maintains a magnetized atomic configuration long term can be described as this.
What is ferromagnetic?
This longest type of electromagnetic wave can either be amplitude modulated or frequency modulated.
What are radio waves?
This person's law uses the inverse square law to describe the electric force between objects with electric charge.
Who is Coulomb?
This phenomenon results in an object where positively charged nuclei are more on one side and negatively charged protons are more on the other.
What is electric polarization?
Homes, schools and hospitals all use this type of circuit to keep themselves bright. Better make sure you have a circuit breaker though because adding more lights reduces resistance.
What is a parallel circuit?
The strength of an electromagnet made using this, loops of wire stacked on top of each other, depends on how many loops there are and how long it is.
What is a solenoid?
Electromagnetic waves are a combination of oscillating electric and magnetic fields in a perpendicular configuration. This is what we call the direction those fields are moving in.
What is wave polarization?
This person's law helps determine what the magnetic field of an object will look like. In its equation, you relate the electric current passing through a closed loop to the strength of the magnetic field pointing along the loop.
Who is Ampere?
This property of electricity, calculated as joules/coulomb, described how electric fields change across distance. Think of it similar to water pressure.
What is voltage?
Camera flashes, keyboards and computer memory all use these devices that store energy by having two conductors separated by some distance. Bring those conductors together and *click*
What is a capacitor?
This piece of a circuit, discussed in the magnetism section of our resource guide, turns AC into DC by only allowing current to flow one way.
What is a diode?
These handy contraptions generate light by having a mixture of semiconductors arranged in such a way that a big chunk of energy is required for electrons to be able to flow and generate current, making light.
What are light emitting diodes or LEDs?
This person's law says that changing a magnetic field can generate a voltage in a wire without any other power source.
Who is Faraday?
This property of electricity, measured in joules/second or watts, describes a rate of energy change over time. I've got the property!
What is power?
Putting this kind of material between two conductors can increase the amount of charge they store. The material becomes polarized, creating its own electric field. Breaking down air, one of these materials, is how we get lightning.
What is a dielectric?
Using the right hand rule, if an electric current is flowing upward, which way will the magnetic field be going?
What is counterclockwise?
This theory describes how one observer can describe an event as occurring due to an electric field, while a different observer will describe the same event as occurring due to a magnetic field. It's why there is no electric force or magnetic force, its all electromagnetic!
What is relativity?
