Properties of Charge
This subatomic particle is the mobile charge carrier in metallic solids.
What is the Electron?
According to the fundamental laws of electrostatics, two protons will do this.
What is repel?
What the invisible influence around an electric charge is called.
What is the electric field?
A material, such as copper, where electrons are free to move throughout the atomic lattice.
What is a conductor?
This common lab device typically uses gold leaves to detect the presence of static charge.
What is an electroscope?
The SI unit of electric charge.
What is the Coulomb (C)?
This is Coloumb's Law
What is Fe=kq1q2/r2
By convention, electric field lines originate from this type of charge.
What is a positive charge?
A material, such as glass or rubber, where electrons are tightly bound to their parent atoms.
What is an insulator?
This common physical connection provides a path for excess charge to flow into the Earth.
What is grounding?
If an object has a net positive charge, it has undergone this change at the atomic level.
What is losing electrons?
This variable represents the proportionality constant in Coulomb's Law
In a diagram, the density (closeness) of the electric field lines represents this.
What is the strength (or magnitude) of the field?
This type of material, when cooled below a critical temperature, allows electric charge to flow with zero resistance.
What is a superconductor?
Opposite charges do this according to the law of electric charge.
This conservation law states that the net charge of an isolated system remains constant.
What is the Law of Conservation of Charge?
Because electric force has both magnitude and direction, it is classified as this type of quantity.
What is a vector?
Electric field lines can never do this.
What is cross (or intersect)?
This metal is highly valuable and used in circuit boards and computer chips due to its conductivity and resistance to corrosion.
What is gold?
This event in the atmosphere occurs when charge builds up in one location and then suddenly moves through a conductive channel.
What is lightning?
This natural symmetry, per Noether's Theorem, leads to Conservation of Charge
What is guage symmetry?
If the distance (r) between two point charges is doubled, the electric force (Fe) changes by this factor.
What is 1/4 (or decreases by a factor of 4)?
The value of the electrostatic constant, k?
9 billion Nm2/C2
The method of charging an object by touching it with another charged object.
What is conduction (or charging by contact)?
If charges are provided multiple paths, they will always 'choose' the path of least this.
What is path of least resistance?
