    • Study Notes

    Electric Field

    • The electric field is a vector field that surrounds charged particles, such as electrons or protons.
    • It is a region around a charged particle where the force of the charge can be detected.

    Strength and Direction of Electric Field

    • The strength and direction of an electric field are determined by the magnitude and sign of the charge, as well as the distance from the charge.

    Unit of Measurement for Electric Field Strength

    • The electric field strength is typically measured in units of newtons per coulomb (N/C) or volts per meter (V/m).
