![]() Today, we will take advantage of that and use measurements of electric potential around different charge configurations to determine the location of equipotential lines, which we will then use to approximate the location of electric field lines. We learned last week that it is straightforward to measure electric potentials using digital multimeters. Draw the conducting shapes (on the conductive paper) onto the plotting paper. Additionally, a convention in drawing equipotential lines is to draw them closer together for large electric field magnitudes and further apart for small electric field magnitudes. Conductive Paper and Plotting Paper Setup. Due to the nature of electric fields, the geometric consequence is that all equipotential lines are perpendicular to electric field lines at all points. Recall the relation between electric field and electric potential. Equipotentials are imaginary lines that connect all points at which the magnitude of the electric field is equal. Draw the corresponding equipotentials from the field lines you just drew.Įquipotential Mapping CONDUCTIVE PAPER CONDUCTIVE PAPER Fig 1 -Two electrodes Fig 2 - A metallic circular ring CONDUCTIVE PAPER CONDUCTIVE PAPER Fig 3-Two horizontal bars serving as parallel plates Fig 4 - ShieldingĮlectric fields emanate from all charge, but they are very difficult to measure directly. Now draw the electric field lines for the four electrode configurations provided to you (see Figures 1 through 4 on the following page). You will be supplied with four electrode configurations already drawn out on conductive paper, which match the copies provided on the worksheet. Then draw the corresponding equipotentials from the field lines you just drew. The electrodes or charged bodies are formed by a line of conductive ink, which has been drawn on the paper and then allowed to dry. Ages 8 and up.Draw in your notebook the electric field lines emanating from a single positive point charge. D-cell battery and digital Multimeter not included. You can even visualize dipoles and quadrupoles by using only the push pins. These equipotential surfaces are actually only simulations of what really occurs for charge distributions in free space as opposed to the conductive paper. ![]() Kit includes: conductive paint, conductive graph paper (25 sheets) and matching non-conductive graph paper (100 sheets), leads with alligator clips, metal and plastic push pins, D-cell battery holder, protractor. No calculation required! Draw a picture, draw your name, draw anything you like! You can easily find the electric fields. By mapping out equipotential lines with a Multimeter you can very quickly draw electric field lines. ![]() Kit contains conductive paint, conductive and non-conductive graph paper, D-cell battery holder, corkboard, push pins, circle template, and 4 colored leads with alligator clips,Įlectric fields can be a difficult concept to grasp - but not with this kit! You can simply draw electric fields for electrode configurations of your own design and hook up a battery.Then connect equipotential field lines to generate electric fields.Simply draw your electrodes, hook up a battery to generate the electric fields, and use a Multimeter or voltmeter to map out the equipotential surfaces. ![]() Easily visualize electric fields generated by electrodes of your own design. ![]()
