The units of electric intensity are:

Correct answer: A. Volt/meter or Newton/coulomb

  • A. Volt/meter or Newton/coulomb
  • B. Volt/meter or meter/coulomb
  • C. Volt/coulomb or newton/coulomb
  • D. Joule/meter or newton/coulomb

Explanation

The two units of electric intensity are volts per meter (V/m) and newtons per coulomb (N/C). The electric field strength (intensity) is measured in volts per meter (V/m). It is a measure of the electric force acting on a charged particle per unit charge. The electric current is measured in amperes (A) or coulombs per second (C/s), as mentioned earlier. The electric charge is measured in coulombs (C). The electric potential difference (voltage) is measured in volts (V). The electric field strength and electric potential difference are related by the equation E = V/d, where E is the electric field strength, V is the voltage, and d is the distance between the charged particles. The electric force acting on a charged particle is measured in newtons (N). The electric field strength and electric force are related by the equation F = Eq, where F is the electric force, E is the electric field strength/intensity, and q is the charge of the particle with the unit coulomb.

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.
