Electrostatics - the study of electric charges
at rest |
|
Charging - transferring electrons in such a way
that either an excess or deficiency is created |
|
conduction - transfer of charge through direct
contact
- electrons move
from high concentration
to lesser
concentration |
|
induction - charging without direct contact of
a
charged object.
A charged object is
brought near an
object which is
grounded. Electrons are then either
attracted from
or repelled to the ground |
