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).
