Electric Charge And Fields - 1

Front 1

Electric Field

Back 1

It is a property associated with matter due to which it produces and experience electric field.

Front 2

Dielectric Strength

Back 2

It is the max. electric field an insulator can withstand without becoming a conductor.

Front 3

Properties of charge

Back 3

i) Conservation of Charge

ii) Additive Property

iii) Quantisation of Charge

Front 4

Coulomb's law of electrostatics

Back 4

Front 5

Principle of superposition of charges

Back 5

Not effected by presence of any other charge.

Force of a given charge is the sum of forces applied by all individual charges.

Front 6

Electric Field

Back 6

It is a region around a charged particle where electric effect can be detected.
