Electricity is the flow of electrons in a material. It can be transferred from one object to another, resulting in the objects having positive or negative charges depending on whether there are more protons or electrons. Like charges repel and opposite charges attract due to the electromagnetic force. Conductors allow charge to flow through them, while insulators do not.

2. a familiar form of energy
energy required to operate
appliances, devices, gadgets
and machines

5. is the continuous flow of
electrons in a material.
Transformed into many other
forms of energy.

6. atoms are neutral (no charge)
the number of positive and
negative particles are equal

7. some objects can lose electrons
and some can gain electrons.
why only electron is
transferred???

8. there is more proton compared to
electrons
so the objects is said to be
POSITIVELY CHARGED

9. there is more electrons compared
to protons
so the objects is said to be
NEGATIVELY CHARGED

10. the number of electrons lost is
always equal to the number of
electrons gained.
LAW OF CONSERVATION OF
CHARGE

11. Charges cannot be
created nor destroyed,
but can be transferred
from one material to

12. an invisible force acting on charge
materials or objects
attract
repel

13. Like charges repel and
opposite charges
attract.

14. happens when a neutral object is
place near a charge object
charges in the neutral object
rearrange such that opposite
charges are brought near each

16. the process of removing excess
charges on an object
providing a ground

17. any object that can be a source of
unlimited electrons in order to
neutralize the charged object
GROUNDING

21. happens when two objects are in
direct contact and rubbing each
other.
as object rapidly strip away, one
loses electron and the other gains

22. process wherein an object is
charged without actual contact to
any other charged object

23. process wherein a neutral object
is charged by direct contact with a
charged object

25. a material that permits chargers
to flow freely within it
metals are usually good
conductors of electricity

26. are materials that hinder the flow
of charges
examples are glass, porcelain,
plastic and rubber

30. a path through which charges can
flow
