The purpose of this experiment was to use charged electrodes on conducting paper and voltmeter to discover electric field. The experiment also discovered the relationship between equipotential lines and electric field lines. The purpose of the experiment was to find if the theory that equipotential lines always run perpendicular to electric field lines hold true. The equation used in this experiment is E = ∆V/∆d. The experimental value yielded a result of y = -100x + 10 and the theoretical yielded a -100 V/m. The percent error between the two values was 0.00%. The experiment showed that the theory of the relationship between equipotential lines and electric field lines hold true. Introduction: The objective of this lab was to analyze the nature of electric fields formed by two dipoles and two parallel line conductors using a digital voltmeter. The purpose is to test the theory that states equipotential lines always run perpendicular to electric field lines. Electric field is defined as a region around a charged particle, within which a force would be exerted on other charged particles. Electric field lines always start on the positive end charges and end on the negative end charge. In the parallel line conductor, the electric field line would run straight down vertically from the top to the bottom. Equipotential lines should always…show more content…
The purpose is to test the theory that states equipotential lines always run perpendicular to electric field lines. The experiment was successful in demonstrating the characteristic of electric field theory. It was learned, that field lines always originate from the positive charge and run towards the negative charge. Equipotential lines are perpendicular to the field lines and curved with the parabolic field lines. The objective of the experiment was met and
