Section uno
the strength of a force
Another name for electric potential is
Iron is ferromagnetic, as opposed to paramagnetic, which means
The speed of light
3x10^8 m/s
Coulomb's law is similar to this equation
the gravitational equation
This subatomic particle is believed to be fundamental
The electron
What is the origin of the use of the word battery in an electrical context?
What is the fundamental unit of magnetism?
The dipole (a north and south pole together)
Blue light is this many nanometers
400
What is this: E = σ/2ε0
Gauss's law
what are the 4 fundamental forces?
strong nuclear, weak nuclear, electromagnetic/electric, gravitational
What specifically is meant by the flow of positive charge?
The flow of electrons from negative to positive make it appear as if positivity is flowing from positive to negative
Draw the right hand rule for the magnetic force
Group 2's answer is incorrect
FM radio works by
having the peaks of the program wave increase the frequency of the carrier wave
Faraday's law finds voltage when
a magnetic field changes around a solenoid
Who coined the term "electric force"
William Gilbert
Why is the current in a parallel circuit higher than the resistance of a series circuit?
The current travels through each resistor individually, so the resistance is lower than if the current had to travel through multiple resistors
Lenz's law is a part of what other law?
Faraday's law
When Einstein introduced relativity, physicists thought that the speed of light was not a constant but rather
relative to a universal ether substance
What is a limitation of Ohm's law?
It's not accurate for all circuits
Explain Gauss's law (what it does and how it does it).
proctor will determine. Keep those boards up!!
What is a dielectric?
Something placed between the two parts of a capacitor that allows the capacitor to have greater current than without a dielectric (must not be a conductor)
What do magnetic fields come from?
moving electric charges
Name Maxwell's equations
Gauss's law, magnetic monopoles, Faraday's law, and Ampere's law
Using Ampere's law, you get B, the magnetic field, by
dividing the permeability of free space times current by the circumference of the amperian loop.
