Where do electric fields come from

Q:You’ve been assigned the task of determining the magnitude and direction of the electric field at a point in space. Give a step-bystep procedure of how you will do so. List any objects you will use, any measurements you will make, and any calculations you will need to perform. Make sure that your measurements do not disturb the charges that are creating the field.

                                               Step By Step Solution

Step 1 of 3:

To find the magnitude and direction of electric field at a space, it is important to make sure that the field is parallel at any point.

A cathode ray system could be the easiest way.

Two parallel electrodes, a medium for charge to travel, a voltage supply, a voltmeter and a measuring scale is required.
