Oct 15, 2023 · Learn about electric field intensity, the strength of the electric field at a point, and its formula, units, and examples. Find out how to calculate the force and motion of a charged particle in an electric field.
Electric field intensity is a vector field we assign the symbol \(\mathbf{E}\) and has units of electrical potential per distance; in SI units, volts per meter (V/m). Before offering a formal definition, it is useful to consider the broader concept of the electric field.
Feb 17, 2023 · The strength of the electric field in the space surrounding a source charge is known as the electric field intensity. Mathematically, an electric field is defined as the electric force experienced by a unit charge.
Since electric field is defined as a force per charge, its units would be force units divided by charge units. In this case, the standard metric units are Newton/Coulomb or N/C. In the above discussion, you will note that two charges are mentioned - the source charge and the test charge.
The SI unit of the electric field is volts per meter (V/m). This unit is equivalent to Newton's per coulomb. These are derived units where Newton is a unit of force and Coulomb is the unit of charge.
When considered in SI units the units of electric field intensity are Newton per coulombs. The electric field intensity is independent of the amount of charge on the test charge particle. It is measured the same all around the source charge regardless of the charge of the test charge particle.
