PHS102: INTRODUCTORY PHYSICS III DR. A. O. ADEWALE Course Outline: Electrostatics, potential and capacitance, dielectrics, production and measurement of static electricity. Current, Ohm’s law, resistance and resistivity, heating, Galvanometers, Voltmeters and Ammeters. D.C. circuits, sources of emf and currents, Kirchhoff’s laws. Electrochemistry. The Earth’s magnetic fields and induction. Faraday’s and Lenz’s Laws. Force on a current carrying conductor. Biot-Savart law. Flemmings right and left-hand rules, motors and generators.
Coulomb’s Law in vector form In vector notation the Coulomb’s law can be written as where is the unit vector along r12 where εo = 8.85 x 10-12C2N-1m-2 = permittivity of free space
