Indicative Content and Learning Activities

Learning Activities
The online platform provided by Pearson is used to have students prepare for each topic/textbook chapter by answering pre-lecture questions. All lectures combine some dissemination of knowledge, small-group discussions on conceptual and selected symbolic and numerical problems, and anonymous polling. At the end of each chapter, students are assigned a Dynamic Study Assignment and about 90 minutes of homework problems and exercises.

Electric charge and Electric field
Electric charge, Structure of matter, conservation of charge, conductors, insulators, induced charge. Coulomb's law, electric field and forces. Electric field calculations. Field lines. Electric dipoles. Introduction to Gauss' Law.

Electric Potential
Electric potential energy: Electric potential energy in uniform fields and point charges. Electric Potential: Calculation of potential, potential as an integral of E. Equipotentials and field lines.

Capacitance, Capacitors and dielectrics
Capacitance in vacuum, capacitors in series and parallel, capacitors network. Link with electric field and electric potential. Energy storage in capacitors. Dielectrics: Induced charge and polarisation

Direct Current Circuits
Current, current flow and drift velocity. Ideal and non-ideal batteries. Surface charges and equipotential lines in dc circuits. Resistivity: Resistance, temperature dependence, I-V plot. Electromotive force of a battery and electric circuits. Energy and power in electric circuits. Resistors in series and parallel. Kirchhoff's rules and analysis of complex circuits. Measuring instruments. RC circuits.

Magnetic Field and Magnetic Forces
Magnetism and magnetic field, magnetic forces on moving charges, magnetic field lines. Motion of charged particles in magnetic field: mass spectrometers. Magnetic force on current carrying conductor, force and torque on a current loop. Mutual and self inductance.

Sources of Magnetic field
Lorentz force. Magnetic force and field. Magnetic field of a moving charge, current element, Biot and Savart law. Magnetic force on a moving charge and a current-carrying loop. Magnetic moment. Current-carrying wire as a source of magnetic field.
