'Static' electricity

In the year 1839, physicists thought that "static electricity" was different from the other electrical charges.In that year Michael Faraday published the results of his experiments on the Identity of Electricities. He demonstrated that the divisions between static, current, etc., were illusions, that all five "kinds of electricity" were the same and that only electricity itself was unique.

Static electricity is an important element in the biological process of pollination by bee's since the charge on a bee's body helps to attract and hold pollen.

Comparison of charge and mass

Charge is a quantity which may be positive or negative but mass is always a positive quantity.
Force between two charges can be attractive or repulsive but force between two masses is always attractive (i.e. Gravitational Force).
Charge doesn't vary with velocity of the object but mass does vary according to the relation

$m= rac{m_0}{sqrt{left(1-left( rac{v}{c} ight)^2 ight)}} !\$ .

Charge is always conserved but mass is not conserved as it can change into energy.
Charge is quantized but quantization of mass has yet to be established.
