Static electricity takes place when there is an excess of
positive (+) or negative (-) charges on an object's surface. This situation is
caused by rubbing specific materials collectively. Static electricity is not
caused by friction, as is commonly thought. Rather, it is caused by the
The atom contains negatively charged electrons, positively
charged protons and neutrons. Generally the number of electrons and protons is
the identical. This retains an electrically neutral and stable condition.
However, whenever two objects make contact or when friction
happens between them, An electron is moved from an atom of one material to an
atom of another material. When this happens, electrons transfer from the material
using a weaker bond to the material using a stronger bond.
With this movement of electrons, the materials lose their
electrical neutrality and static electricity is accumulated. The material that
drawn the electron is negatively charged and the material from where the
electron was lost is positively charged. This is the system for the Generation
of Static Electricity.
Examples of Static Electricity
Walking around a carpeted floor and getting a shock when
touching a door knob or some other metal object is an example of static
electricity. Clothes stuck to one another following being in the dryer is
another example of static electricity.
If someone wearing a wool and he or she removes the hat, his
or her hair becomes electrically charged. The wool rubs against the hair once
the hat is removed, moving electrons from the person's hair to the hat. This
leaves the hair positively charged.
With electricity, opposites attract and stuff that have the
identical charge repel. The positively charged hair stands on end and sticks up
since it is repelled by the other positively charged hairs on the head. The
greater rubbing between two objects, the greater static electricity develop and
the bigger the electrical charge.
How to Measure Static Electricity
Measuring the static electricity is essential. It enables
you to find out if there is static existing, its size and where it is being
Static charge is measured in charge for each unit area,
generally in units of µC/m2
The electric field acts in unique ways and should be
understood. One of the most interesting features of the electric field, which
is extremely important when attempting to measure the charge.

it can be paired with other bodies with crucial consequences
for measuring and neutralizing the charge.
Once the charged material moves over a roller,
for instance, the electric charge couples with the roller and appears to
disappear. It is difficult to make an accurate measurement close to the roller.
The electric field returns once the material leaves the roller and thus can be
