Lab ReportPHY 2049L or PHY 2054LDate Performed: January 22, 2013Mapping of Electric FieldsAuthor:BlessedAbrahamPartners:MajesticBelovedVelvetBelovedFebruary 5, 2013(5pts)
1Objective(5 pts)In this is lab, we willLearn the concept of electric field lines and equipotentialsExperimentally search points in an electric field, having the same potential (equipotential lines)Use the equipotential lines for drawing electric fieldCalculate the magnitude of the electric field2Background and theory(10 pts)2.1Electric Filed(2.5 pts)An electric field consists of a distribution of vectors in every point around an isolated charged of object, suchas a charged rod.Any particle of positive chargeq0,placed at any point,P,in the vicinity of a chargedobject, is subject to anelectric force,~F: at any pointPIn its vicinity, thecharged object, sets upanelectric field,~E,that creates anelectric force,~F,acting on the test chargeq0.This electric field isdefined as:~E=~Fq02.2Electric field lines(2.5 pts)Michael Faraday, who introduced the idea of electric fields in the 19th century, thought of the space arounda charged object as filled with lines of force also calledelectric field lines.Electric field lines are usefulfor visualizing the pattern of the of electric field. The field lines are related to the electric field by this:Lines force are the path traversed by a test charge as it moves from one point to another in the field.The electric field is tangent in every point of that path.
