KEY TAKEAWAYS •
The charge on an electron is negative, while the charge on a proton is positive.
•
The electron and proton are the smallest units of charge in nature, although theoretically, quarks have a partial charge within a proton.
•
The SI unit of charge is the coulomb.
•
Charge is always conserved, according to the law of conservation of charge.
•
An electric field is generated from positive to negative from two charged objects.
•
A conductor will be polarized within an electric field but will have no electric field within it.
•
Two charged objects can produce an electric field, which is the sum of the force vectors between the two objects.
•
A nonuniform conductor will gather and discharge a charge when the conductor is at its pointiest.
