The number of lines per unit area passing perpendicular through an area is called:
Correct answer: A. Flux
- A. Flux
- B. Electric intensity
- C. Both (a), (b)
- D. None of these
Explanation
Flux refers to the number of lines of a field (e.g., electric or magnetic) passing perpendicularly through a unit area. It is a measure of the field strength across a surface and is mathematically defined as the surface integral of the field.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
