Electric field strength is defined as the force experienced by a unit positive charge placed in an electric field. This concept is essential for understanding how electric charges interact with each other, allowing us to quantify the influence that electric charges exert on their surroundings. The electric field strength at a point in space is represented by the symbol $$E$$ and is measured in newtons per coulomb (N/C). It is directly related to the distribution of charges and can be calculated using Gauss's law, which relates the electric field to the charge enclosed within a closed surface.
congrats on reading the definition of Electric Field Strength. now let's actually learn it.
