Third Grading Module 6 Electricity

a familiar form of energy

energy required to operate

appliances, devices, gadgets

and machines

atoms are neutral (no charge)

the number of positive and

negative particles are equal

some objects can lose electrons

and some can gain electrons.

why only electron is

transferred???

the number of protons and

electrons are not anymore equal

there is more proton compared to

electrons

so the objects is said to be

POSITIVELY CHARGED

the number of protons and

electrons are not anymore equal

there is more electrons compared

to protons

so the objects is said to be

NEGATIVELY CHARGED

the number of electrons lost is

always equal to the number of

electrons gained.

LAW OF CONSERVATION OF

CHARGE

Charges cannot be

created nor destroyed,

but can be transferred

from one material to

another.

an invisible force acting on charge

materials or objects

attract

repel

Like charges repel and

opposite charges

attract.

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

other

the process of removing excess

charges on an object

providing a ground

any object that can be a source of

unlimited electrons in order to

neutralize the charged object

GROUNDING

happens when two objects are in

direct contact

as object rapidly strip away, one

loses electron and the other gains

electron

a material that permits chargers

to flow freely within it

metals are usually good

conductors of electricity

are materials that hinder the flow

of charges

examples are glass, porcelain,

plastic and rubber

process wherein an object is

charged without actual contact to

any other charged object

process wherein a neutral object

is charged by direct contact with a

charged object

a path through which charges can

flow
