2. Static Electricity
Static electricity (elektrostatic) is a collection of
large amounts of electric charge, the static (no
flow), but in case of discharging the charge time
is very short.

3. A. How Generates Electricity Charged
Objects
Electrically Example :
charged object is an
object that have
excess or shortage
of electrons. Some
simple ways to
create static
electricity are:
4. B. Types of Electrostatic Discharge
Getting a positive
In the atom consists of a electric charge on
nucleus and electrons. an object by
The nucleus consists of induction
protons and neutrons,
positively charged
protons and uncharged
neutrons (neutral). Atom Netral
is called neutral if the
number of protons in the
nucleus equals the
number of electrons
surrounding the nucleus.
Positive atom is an atom
that has more positive
charge than negative Bumi
charge.
5. C. Coulomb law
Charles Augustin de Coulomb was the first to examine the relationship
with the two charge electric force and the distance between them by
using a torsion balance. In that study ultimately concludes Coulumb in a
law called the law of Coulumb:
large repulsion ataugaya attraction between two electrically charged
objects, is directly proportional to the respective electric charge and
inversely proportional to the square of the distance between the two
charged objects.
Mathematically, Coulomb's law can be formulated:
F = gaya coulomb ( N )
q1 q 2 q = muatan ( C )
F k 2 r = jarak ( m )
r k = ketetapan 9.109
Nm2/C2
6. D. Electric induction
Electrical induction or influensi induced
charge separation event electricity is
electricity (electron transfer) as approached
by electrically charged objects.
7. E. Electric field
The electric field is the E F E

magnitude of electric r
field strength can be E = medan listrik ( N/C )

formula: q = muatan uji ( C )
r = jarak dari benda ( m )
F = Gaya ( N )
8. F. Electric potential
Electric potential is the effort needed
to move electric charge from one place
to another by the amount of cargo.
Electrical potential is formulated:
W
V= Q
