Electrostatic Series: The arrangement of

materials according to the easiness of losing
electrons when rubbed together

When one material is rubbed with another:
? The material higher on the series +ve charged (Tends to lose electrons).
? The material lower on the series -ve charged. (Tends to gain electrons).

A single material can be charged with wither +ve / -ve charge depending on
the type of its rubbing material and its order in electrostatic series

?Weak electric charges are measured

using a device known as a coulomb meter Coulomb meter
and are measured in units of coulombs.

The Scientist Charles- Augustine de Coulomb

-A French physicist who formulated the law
describing electric forces between charged
particles named after him (Coulomb's Law), also
known as the inverse-square law.

- His studies and discoveries in the late 18th
century laid the foundation for the development of electromagnetic theory.

-In his honor, the unit of electric charge of Coulomb was named after him.
