Electrostatics Flashcards
Elementary charge
An indivisible unit of charge
Polarisation (of charge)
The partial or complete polar separation of positive and negative electric charge in a system
Principle of conservation of charge
The net charge of an isolated system remains constant during any physical process
Principle of charge quantisation
All charges in the universe consist of an integer multiple of the charge on one electron
Tribo- electric charging
The process whereby objects are charged by contact or rubbing
The polarity and strength of the charges produced differ according to the materials
What do all materials contain
All materials contain Positive charges and negative charges
What are positive and negative charges
Positive charged object ls are electron deficient
Negative charged objectd have an excess of electrons
Si unit of electric charge
C( coulomb)
The Property of particles in atoms that enable tms to attract and repel
Is called charge
Why are charges called positive and negative
Because when the two types coke together they cancel out to produce zero
A charged object attracted to a neutral conductor
A charged object can be attracted to a neutral conductor because of the movement of charges in the conductor
A charged object attracted to an insulator
A charged object can also be attracted to an insulator because of the movement of polarised molecules present in the insulator
What type of molecules have one side more positive and one side more positive
Water
