Question

)Define following terms & also state its formula & S.I. unit.

  a) Linear charge density  b) Surface charge density c) volume charge density

​

Answer 1

A) Charge density is a measure of electric charge per unit volume of space, in one, two or three dimensions.

The SI unit of linear charge density is the coulomb per meter (C/m).

B)The surface charge density is present only in conducting surfaces and describes the whole amount of charge q per unit area A.the SI system in coulombs per cubic meter (C. m−3), at any point in a volume.

c)charge density is the amount of electric charge per unit length, surface area, or volume.

the SI system in coulombs per cubic meter (C. m−3), at any point in a volume.
