Charles Coulomb
The Coulomb is called or charge and is the smallest amount of charge.
fundamental, elementary
The charge on ANY object is a whole number multiple of the charge on one electron. This is called charge __.
quantization
Charge comes in quantities, or __ amounts, due to the fact that you can’t divide electrons.
discrete
Surrounding charged objects is an “area of influence” known as an .
electric field
Electric forces are described by __ Law.
Coulomb’s

Contact occurs mostly in __ materials.
conductive
Initially neutral object takes on the __ sign charge as the object it comes into contact with.
same
Induction occurs mostly in __ materials
conductive
When combined with a grounding step, initially neutral object takes on the __ sign charge as the object it comes close to.
opposite
__ is the process of neutralizing an object’s charge.
Grounding
is a type of charge induction
