What Is Electric Field Intensity? The space around an electric charge in which its influence can be felt is known as the electric field. The electric field intensity at a point is the force experienced by a unit of positive charge placed at that point. Electric field intensity is a vector quantity. It is denoted by ‘E’.
Oct 15, 2023 · In this article, we will learn about electric field intensity, its formula, units, the difference between electric field intensity & electric field, and the force experienced by a charge in an electric field along with some solved examples.
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.
