Electric field inside wire formula
WebFigure 12 shows a wire made of a conducting material such as copper.By some external means, an electric field is established inside the wire in a direction along its length. The electrons that are free to move will gain some speed. Since they have a negative charge, they move in the direction opposite that of the electric field. WebMathematically, saying that electric field is the force per unit charge is written as. E → = F → q test. 18.15. where we are considering only electric forces. Note that the electric field is a vector field that points in the same direction as the force on the positive test charge. The units of electric field are N/C.
