Question

Electric Fields -Prelab Name ate:n 3 2014 Lab day & time:.00p Question: What do the electric fields produced by charged conductors look like? Part P -1: In this lab you will be investigating the nature of the electric field. You will be using an electric field mapping aparatus in this laboratory. Here we will ask you to make a few predictions based on what you know at this time about what you expect. You will be asked later to comment. Bellow are two different electrode diagrams that you will investigate in the lab. Please make a prediction on what you expect to observe in the electric field. You will have to read the lab to make this prediction. Circular Electrodes Electric Field Grid 34%6789101112132425 You do not have to worry about numbers here. We just want to establish some idea of what to expect. In two separate paragraphs describe the reasoning for each of the sketches you made of the field lines above.

Answer 1

Okay, here as this is a lab based question, I have drawn electric field lines from what I know about electric field

For circular electrodes, the electric field lines will start from positive electrodes and will end at negative electrode. The diagram will look something like this

For the parallel plates, it will be like this

As we can see, In case of circular electrodes , the electric field lines propagate in all the directions and with two opposite charges nearby, this field lines will interfere and give a combined field given as above.

For plate electrodes, same concept applies except in this case the field lines are more of a straight lines.
