Famous Physicists
He proved lightning was electrical using a key and a kite.
Benjamin Franklin
The two particles found in the nucleus of an atom.
Protons and Neutrons
This law states that electric charge cannot be created or destroyed.
Conservation of Charge
This percentage of American homes had electricity by 1930.
Nearly 70%
This tool uses a small magnet to point toward Earth's magnetic north.
Compass
This type of field always points toward the center of the Earth.
Gravitational Field
He coined the term "electricity" in 1600 while experimenting with amber.
William Gilbert
This particle orbits the nucleus and has a negative charge.
Electron
This 1785 law describes the electric force between two charged objects.
Coulomb’s Law
This appliance became widely popular in the 1920s, bringing news into homes.
Radio
Magnetic fields are produced by charged particles only when they are doing this.
Moving (in motion)
This concept allows us to simplify calculations for regular geometric shapes.
Symmetry
This humble scientist discovered how to create electricity with moving magnets.
Michael Faraday
This term describes the smallest indivisible unit of an element.
Atom
It is the mathematical connection between voltage, current, and resistance.
Ohm’s Law
By 1929, this percentage of American manufacturing was electrified.
70%
He discovered that a current-carrying wire could deflect a compass.
Hans Christian Oersted
The net electric field everywhere inside this type of charged object is zero.
Conductor (e.g., a metal sphere)
He developed a set of equations that unified electricity and magnetism.
James Clerk Maxwell
This is the term for the smallest "discrete, countable" amount of charge.
Quantized
This law relates the electric field flux through a surface to the charge inside.
Gauss’s Law
This 1859 solar event caused telegraph systems to fail and wires to catch fire.
The Carrington Event
This device uses a changing magnetic field to step voltage up or down.
Transformer
This "cage" shields its contents from electromagnetic radiation.
Faraday Cage
He published a 1905 paper on the electrodynamics of moving bodies.
Albert Einstein
Protons and neutrons are made of these even smaller fundamental particles.
Quarks
Voltage is often referred to by this 3-letter term in circuit contexts.
EMF (Electromotive Force)
This inventor famously campaigned to discredit Alternating Current (AC).
Thomas Edison
This medical machine uses some of the strongest magnetic fields encountered.
MRI (Magnetic Resonance Imaging)
This "surface" is an imaginary boundary used to calculate electric flux.
Gaussian Surface
