# Experiment 1: Equipotential Lines and Electric Fields.

Comparing the equipotential line patterns with the electric field patterns in Part A of Experiment C3Experiment C3 is sprinkling semolina powder onto the non-conducting oil in an electric field. The powders then form lines, which are electric field lines.The direction shown on an electric field line is the direction of the force acting on a free positive test charge. Carley Costner Physics Lab 1104 Eclectic Fields Conclusions During the first activity, we hypothesized that the electronic fields would produce circle like points around the negative and the positive charges and would expand further out as the voltage increased. The findings when preforming this experiment proved our hypothesis as correct. During the experiment we found the equipotential lines. Also, to map electric equipotential lines and electric field lines for two-dimensional configurations. Procedure: Starting the first of two parts of our lab (part A), we began by setting up our equipment. We first set up our conducting paper and pushed two aluminum push pins into each of the two conducting metallic holes on the paper. To visualize an electric potential interaction between two electrodes and to sketch the resulting configuration as it creates a 2-dimensional electric field that can be used to map 2-D, equipotential lines. Method: With an electric potential meter (also known as a volt meter or Galvanometer), find points on the paper that have no potential.  Experiment 3: Electric Fields and Electric Potential Introduction In this lab we will measure the changes in electric potential (V) using a digital multimeter. We will explore the relationship between equipotential surfaces and electric field lines and use this to. Electric Fields and Potentials By: Alexis Huddleston. Introduction: The purpose of this experiment was to gain an understanding of electric fields and their potentials by using volts and point strategies.The electric potential as stated in this activity is created by the distribution of charges, which is a scalar quantity, determined by the different locations of voltage charges.

## Experiment 3: Electric Fields and Electric Potential. Finally, draw in the electric field lines corresponding to these 7 equipotential lines, produced by the electric dipole source charge configuration. Be sure to distinguish your electric field lines from your equipotential lines using a legend, and place arrows on the electric field lines to indicate their direction. The lab is about Electric Fields and Equipotentials ! What are electric field lines? What do they tell you about the movement of charges (answer for positive charges and negative charges)? What are equipotentials? Why don't they have directions associated with them like field lines? Where. Equipotential and Electric Field Mapping 1.1 Objectives 1. Determine the lines of constant electric potential for two simple con- gurations of oppositely charged conductors. If you work to understand these two, the same principles will apply to all charge configurations. 2. Determine the electric eld from lines of constant electric potential. 3. Experiment 1: Equipotential Lines and Electric Fields OBJECTIVES 1. To develop an understanding of electric potential and electric fields 2. To better understand the relationship between equipotentials and electric fields 3. To become familiar with the effect of conductors on equipotentials and E fields PRE-LAB READING INTRODUCTION. An electric field is created when anelectron and a proton are in the same conductor. This electric field will have a force,which will lie in lines connecting them. Equipotential lines, which go from one chargeto another, have the same electric potential along the line, and describe the surface onwhich the electric field has a constant value. Electric Field Mapping. Objectives: 1) To learn the concepts of electric field lines and equipotentials, and. 2) use the equipotential lines for drawing the electric field lines. Equipment: A computer with the Internet connection, paper, and pencil. Theory: Electric field lines around a positive point charge are directed radially outward. Equipotential and Electric-Field Mappina In this lab, we will map the lines of equipotential and electric field for different configurations. Equipment Pasco Equipotential and Field Mapper Power supply Connectors Conducting paper Graph paper Multimeter Procedure (1) Attach the conducting paper with two point charges to the cork board using pins provided in the box - these pins act as electrodes.

## Electric Fields and Potentials - Odinity.

Conclusion For the experiment, the group aimed to understand the concept of electric field, electric field lines. and equipotential lines and to also find the electric field lines from equipotential lines. The group did this by getting 10 x and y coordinate along the glass pool which registers the same voltage. The process was repeated from 1V.The purpose of this lab is to experimentally map the positions of seven equipotential surfaces on each of two already prepared field maps. After locating these surfaces, electric fields lines will be constructed to reveal two classic electric field configurations.The electric field lines and equipotential lines for two equal but opposite charges. The equipotential lines can be drawn by making them perpendicular to the electric field lines, if those are known. Note that the potential is greatest (most positive) near the positive charge and least (most negative) near the negative charge. Figure 3.
