Electric field in charged tube
WebThe dimensions of electric field are newtons/coulomb, \text {N/C} N/C. We can express the electric force in terms of electric field, \vec F = q\vec E F = qE. For a positive q q, the electric field vector points in the same … WebThis technique is used in most vacuum tubes. Field electron emission: A strong electric field can be applied to the surface by placing an electrode with a high positive voltage near the cathode. The positively charged electrode attracts the electrons, causing some electrons to leave the cathode's surface.
