The electric flux density is the - Electromagnetic Field Theory

Electronics and Communication Engineering (ECE) : Electromagnetic Field Theory - Quiz(MCQ)

The electric flux density is the

Product of number of flux lines and permittivity

Product of permittivity and electric field intensity

Product of number of flux lines and permeability

Product of permeability and electric field intensity

Correct Answer : Option (B) : Product of permittivity and electric field intensity

Explanation : D= εE, where ε=εoεr is the permittivity of electric field and E is the electric field intensity. Thus electric flux density is the product of permittivity and electric field intensity.
