1 HB Electric Field Mapping Lab 3 1 Electric Field Mapping Lab 3 Equipment mapping board, U-probe, resistive boards, templates, dc voltmeter (431B), 4 long leads, 16 V dc for wall strip Reading Your textbook. Precautions 1. Before turning mapping board over, remove voltage leads from board. 2. Turn mapping board over by grasping two diagonal corners of board. Please do not grasp edges of mapping board, which may break a wire underneath the board near the edge. 3. Handle resistive boards carefully by edges. It is easy to scratch the resistive coating. 4. During the experiment, keep checking that the knurled nuts, particularly the one to the U-probe, are tight. 1 Description and Theory The force between charged particles is attributed to an electric field E which has the dimensions of force per unit charge. A charge q in the presence of an electric field produced by other charges experiences a force qe. Another useful quantity is the voltage or potential (these two words are equivalent), which have the dimensions of work per unit charge, or in S.I. units, joules/coulomb (J/C). This last combination of units, J/ C), is called the volt (V). The potential between two points a and b, or the potential at a with respect to b, is given by V a V b = V ab = b a E d l, where d l is a differential displacement. If a surface is constructed so that the electric field E is always perpendicular to it, the potential difference between any two points on the surface will be zero. The surface has a constant voltage and is called an equipotential surface. If several charged conductors exist in a region of vacuum or air, electric field lines and equipotential surfaces can be constructed. A voltmeter is an instrument that has two metal probes. If the two probes are put in contact with any two conductors, the voltmeter will give the voltage or potential between the two conductors. But the voltmeter will not give the voltage between two points in vacuum or air because vacuum or air cannot supply the necessary charge or electrical current necessary to make the voltmeter work. It can be shown that if perfect conductors are embedded in a homogeneous resistive medium, the electric field and equipotentials are the same as in vacuum. This is the technique used in this experiment. Highly conducting paint is used to paint electrodes on a flat resistive board. Voltage differences are applied to the electrodes and the equipotential surfaces in the resistive medium are found by using a voltmeter. This experiment is two, not three, dimensional, as the conducting board is a flat thin sheet. The equipotentials that you measure will be lines, not surfaces. The equipotentials obtained in this experiment are equivalent to those that would be obtained if the electrodes extended to infinity both into and out of the resistive board, and the material between the electrodes was everywhere a uniform homogeneous isotropic dielectric or resistive medium.

2 HB Electric Field Mapping Lab Mapping and Resistive Boards The resistive boards are semi-insulating and have patterns painted on them with a highly conducting paint. Each painted area ( electrode ) has a constant potential. When the positive terminal of a power supply is connected to one of the electrodes and the negative terminal of the power supply connected to another electrode every part of the resistive board attains a potential that depends on the shapes, orientations, and positions of the electrodes. The potential of any point on the board can be measured with a voltmeter. There are five patterns available on resistive boards (see Fig. 1). These patterns are 1. two small circles, 2. two parallel rectangles, 3. a small circle and a rectangle, 4. a small circle and a, and 5. two small circles which are connected to the voltage cource, and a conducting circle and a non-conducting circle which are not connected to the voltage source. In this experiment, use patterns 3-5. (Patterns 1 and 2 are similar, but not identical, to diagrams in your textbook.) Remember, the equipotentials you measure are the same as if the electrodes extended into and out of the board and that everywhere the inter-electrode material was a dielectric or resistive medium. Board 1 simulates two oppositely charged long wires that are in vacuum. This is the simplest situation, as you have a pretty good idea what the equipotentials look like. Board 2 simulates capacitor plates. It is interesting to see what the fringing field lines look like. Boards 3 and 4 are variations of these ideas. Board 5 is the most complex; it is interesting to see what happens to electric field lines when a conducting body or an insulating body is placed between two charges. Can you guess in advance what happens? Will the field lines pass through the bodies, or go around them, or what? The electric field mapping apparatus is designed so that the resistive board is mounted on the bottom (see Fig. 2). Remove the two leads from the Bat or Osc terminals of the resistive board if they are attached. Hold the mapping board by two diagonal corners and turn it over so that the legs jut upward and the resistors can be seen (Fig. 2a). (If you hold the apparatus along the edges, it is all too easy to break a wire underneath.) Holding a resistive board carefully by the edges, place the resistance board on the mapping board the with pattern side visible so that the contact screws of the mapping board go through the two holes in the resistive board. Place a washer over each screw and fasten the board to the apparatus with two knurled nuts. The washers are essential for good electrical contact, and the nuts should be tightened by hand until they are snug, but not excessively tight. Now turn the apparatus right side up so that the two electrical binding posts and rubber knobs are visible. Lay a piece of paper on top of the apparatus, push down on the apparatus board to raise the rubber knobs above the board, and insert the corners of the paper under the rubber knobs. The mapping board has a chain of 8 equal resistors that divide the voltage difference that is applied to the two electrodes into 8 equal intervals. There are 7 jacks that allow you to access these voltages. One lead of the voltmeter is connected to one of these resistor jacks and the other voltmeter lead is attached to a U-probe. One end of the U-probe has

4 HB Electric Field Mapping Lab 3 4 lines or surfaces to touch or cross? (Hint. In your text book, see if you can find a figure with the equipotentials of two positive point charges.) 3. What is the direction of the equipotential lines near the edges of the electrodes? 5 Electric Field Lines Electric field lines are drawn so that they are always parallel to the electric field and their density is proportional to the magnitude of the electric field. Draw electric field lines perpendicular to your equipotential lines, putting lines closer together where the electric field is stronger. Include arrows on the field lines to show the direction of the electric field. The direction can be inferred from the polarity of the connections going to the electrodes. Answer the following questions. 1. If the polarities of the electrodes are reversed, how do the patterns of electric potential and field change? 2. Is it possible for electric field lines to cross? Explain. 3. What feature of the equipotential map indicates where the electric field is strongest? Why? Is the electric field strongest where you expect it to be? 4. Explain in your own words why a surface that always has E perpendicular to it is an equipotential. 6 Finishing Up Please leave the bench as you found it. Thank you.
