2 Welcome to Physic course SC 442 Honor section

3 For your knowledge!!! The presentation that you are about to witnessed has been conducted the 02 February 02 with the complete collaboration of Xi Hi Li Today as the research project of the Fall 2002 we present the

4 Mapping of Electric Field

5 The Plan Introduction Some History The Theory The Objectives Equipments Used The Procedure More Idea My Conclusion

6 History Niel Bohr (Danish) Charles Augustin de Coulomb (French) Michael Faraday (British)

7 Theory

8 . The Bohr’s Atom

9 Coulomb's Law The charges of the same charge repel & the Charges of different charges attract

10 The Coulomb Force

11 The Faraday Work

15 The electric field

16 The Electric Field

17 Constant Electric Field

18 Electric field as Gradient (R^3)

19 OBJECTIVES To determine the shape of equipotential surfaces and electric field lines associated to a dipole with: a) two point charges b) two parallel plates, and to compare each of these to theoretical predictions

20 The Equipments

21 DC power supply

22 Transformer (step down)

23 Connecting Wires

24 Galvanometer

25 Voltmeter

26 Field mapping

27 Two Probes

28 Two probes & Board

29 The Procedure

30 Two Circuits

31 Circuit 1

32

33

34 Circuit 2

37 Electric field Distance between probes ∆x, m Potential difference ∆V,V Electric Field E=dV/dx N/C

38 Are electric and magnetic fields different? Electric fields are produced wherever there is a voltage Electric fields can be shielded easily Magnetic fields are produced by current - the quantity of electricity flowing. While magnetic fields cannot

39 Electric Field Vs Magnetic Field Electric fields are measured in volts per meter (V/m ) magnetic fields in tesla (T), or amperes per meter (A/m).
