Electric Flux A measure of the electric field passing through a surface, influenced by the field's angle to the surface's normal. Electric Field A field around charged particles that exerts force on other charges, represented by field lines. Surface A boundary through which electric field lines pass, affecting the calculation of electric flux. Normal A vector perpendicular to a surface, used to determine the angle with electric field lines. Angle The measure between the electric field lines and the normal, affecting the electric flux value. Closed Surface A boundary enclosing a volume, like a box, used to calculate total electric flux. Positive Flux Occurs when electric field lines and the normal point in the same direction, resulting in a positive value. Negative Flux Occurs when electric field lines and the normal point in opposite directions, resulting in a negative value. Total Flux The sum of electric fluxes through all surfaces of a closed boundary. Area Vector A vector representing the magnitude and direction of a surface area, used in flux calculations. Cosine A trigonometric function used to calculate the component of the electric field through a surface. Gauss's Law A principle relating the electric flux through a closed surface to the charge enclosed. Net Electric Flux The overall electric flux through a closed surface, accounting for positive and negative contributions. Field Lines Imaginary lines representing the direction and strength of an electric field. Perpendicular Vector A vector at a right angle to a surface, synonymous with the normal in flux calculations.
