Electric field of cylinder formula
WebThe electric field does not become "diluted" when there is a greater surface area. It has a relationship that is inversely proportional to the area of the wire's cross section. If the cross section of the wire has a larger area, the resistance will be lower, and if the area has a smaller cross section, the resistance will be higher. WebThe electric field inside the inner cylinder would be zero. When drawing electric field lines, the lines would be drawn from the inner surface of the outer cylinder to the outer surface of the inner cylinder. For the excess charge on the outer cylinder, there is more to consider than merely the repulsive forces between charges on its surface.
