Welcome to Physic course SC 442 Honor section

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

Mapping of Electric Field

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

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

Theory

. The Bohr’s Atom

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

The Coulomb Force

The Faraday Work

The electric field

The Electric Field

Constant Electric Field

Electric field as Gradient (R^3)

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

The Equipments

DC power supply

Transformer (step down)

Connecting Wires

Galvanometer

Voltmeter

Field mapping

Two Probes

Two probes & Board

The Procedure

Two Circuits

Circuit 1

Circuit 2

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

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

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).
