Write a brief summary of the experiment you performed today. in your summary, think about the following questions: • why is measuring equipotential lines an important activity? • today we measured equipotentials, which are lines that connect points at which the magnitude of the electric field is equal. can we tell anything about the direction of electric field lines with these measurements? propose some additional measurements that would allow us to determine directionality. • in today's lab, we have measured equipotentials in relatively simple configurations. can you think of any more complex systems or configurations where this measurement might be important to making an electronic device function properly? describe your thinking.
