The unit of Electric field intensity is:
Correct answer: B. Newton/coulomb
- A. Volt/metre
- B. Newton/coulomb
- C. Joule/Coulomb.metre
- D. volt.metre
Explanation
The electric field intensity is defined as the force experienced by a positive test charge divided by the magnitude of the charge. Mathematically, it is represented as: E = F/q The unit of force is Newtons (N) and the unit of charge is Coulombs (C). Therefore, the unit of electric field intensity is: E = N/C Therefore, option b is correct.

About Electric Field Intensity
Electric field intensity is the force acting per unit positive test charge, with direction set by the force on that charge. Work includes fields of point charges, vector superposition, field lines and the relation between field and electric potential. Field intensity must be distinguished from electric force and potential.
