What are Conductors and Insulators...

 Conductors and Insulators
According to the electrostatic behaviour, materials are divided
into two categories : conductors and insulators (dielectrics).

Bodies which allow the charges to pass through are called conductors. e.g.
metals, human body, Earth etc. Bodies which do not allow the charges
to pass through are called insulators. e.g. glass, mica, ebonite, plastic
etc.

Two kinds of charges
(i) If a glass rod is rubbed with a silk cloth, it acquires positive
charge while the silk cloth acquires an equal amount of negative charge.
(ii) If an ebonite rod is rubbed with fur, it becomes negatively
charged, while the fur acquires equal amount of positive charge. This
classification of positive and negative charges were termed by American
scientist, Benjamin Franklin.
Thus, charging a rod by rubbing does not create electricity, but
simply transfers or redistributes the charges in a material.
