Electric Charges & Fields
Flash cards
Introduction
A matter is made of few fundamental particles e.g. electrons, 
protons, neutrons etc.
Apart from other properties, the particles (e-, p+) possess 
mass and charge.

Charge and its properties (continued)
1 The charge is the property associated with matter, which 
produces and experiences electrical effects. The study of 
electrical effects of charge at rest is called electrostatics.
2 S.I. Unit of charge is coulomb.

Charge and its properties (continued)
3. A charge body attracts uncharged or neutral body.
4. There is force of repulsion between same nature of 
charges.
5. Charge is quantized, charge on any body is integral 
multiple of electronic charge.

6. For an isolated system total charged remains constant 
although there may be some redistribution of charges within 
the constituents of the system.
