This book is an algebra based treatment of electricity, magnetism and introduction to modern physics. The concepts discussed include electric forces and fields, electrical energy and potential difference, capacitance, Ohm’s law, resistance, Kirchoff’s rules, magnetic forces and fields, circuits, Faraday’s law and Lenz’s rule, properties of light such as reflection, refraction, dispersion, interference and polarization, properties of images formed by mirrors and lenses, introduction to relativity and quantum mechanics, Bohr’s model of the atom, radio activity, binding energy and nuclear reactions.
