Question

1. Describe a uniform electric field. 2. Explain a practical method to create a uniform electric field. 3. In the electrode configuration of Figure 3-a, notice that the equipotential lines are circles which are closer to each other near the point terminal. Explain. (Hint: refer to the relation of the electric field around a point charge, and the relation where DV is the difference in potential between any two points, and r is the distance between them.) 4. In principle, how many equipotential lines can be drawn between a pair of electrodes? What factors limit the number of equipotential lines that can be drawn experimentally?

Answer 1

Uniform electric field: - rightarrow if the electric field lines are parallel and equidistant from each other than it is taken as uniform electric field. practical method to creates uniform field rightarrow We can create uniform electric by 2 methods (i) Between the capacitor plates (ii) By large infinite sheet
