OVERVIEW

The Physics II course deals with two of the main classical physics subjects: thermodynamics and electromagnetic theory

 

AIMS AND CONTENT

LEARNING OUTCOMES

The specific training objective is to provide the student with the ability to solve elementary but concrete problems. This implies that the student must know how to distinguish between fundamental concepts (electric and magnetic fields and forces, works, Gauss's laws, Ampere's, Faraday's, ...) and more specific issues (motion of charges in electromagnetic fields, cylindrical condensers, .. .) demanding a thorough understanding of fundamental concepts.

PREREQUISITES

The basic mathematical knowledge to follow the lecture is
•    Calculus, first and second order (quadratic) equation
•    Basic trigonometry
•    Function of a real variable and its derivatives
•    Basic planar and solid geometry
Other mathematical tools will be introduced or recalled during the lectures.

 

  •  

Teaching methods

Lessons dealing with both theory and exercises

 

SYLLABUS/CONTENT

Thermodynamics

Thermodynamic systems. Temperature: operational definition, thermometric scales. Heat: operational definition, specific heat, latent heat. Heat transmission. Equation of state of perfect gases and real gases. Work in thermodynamic transformations with volume variation. Internal energy. First law of thermodynamics. Specific heats and gas molars. Equipartition Theorem. Second law of thermodynamics. Thermal machines. Refrigeration machines. Entropy and second principle. Absolute thermodynamic temperature.

 

Electromagnetism

Forces between point charges (Coulomb's law). Electric field. Calculation of the electric field through the sources: superposition principle, Gauss’ law. Electric potential, energy of a charge in an electric field. Energy of a system of charges. Analogies with the gravitational field.

Conductor properties. Capacitors. Energy density of the electric field.

Electric current. Ohm's law. Joule effect. Generators. Circuits with one or more meshes. Kirchhoff's laws. RC circuits.

Definition of magnetic field (Lorentz force). Forces on a current-carrying conductor. Mechanical moment acting on a current conducting loop. Magnetic moment of a spire. Methods for determining the magnetic field produced by currents: Ampère’s law, Biot-Savart’s law.

Flow of the magnetic field through a closed surface concatenated with a closed line. Faraday's law. Self-induction. RL and RLC circuits. Energy density of the magnetic field.

 

RECOMMENDED READING/BIBLIOGRAPHY

Any "General Physics" book at university level discusses the subject of the course.

In any case, the main reference for for the course is: D. Halliday, R. Resnick, J. Walker, Fundamentals of Physics 10E – Theory

EXAMS

Exam description

EXAM: written and oral exams

The written exam precedes the oral exam and must be passed with a sufficient grade to be admitted to the oral exam.

 

 

Assessment methods

Students will evaluated on:

- the knowledge of the course contents

- problem solving skills

- ability to handle and comunicate the arguments discussed during the lectures
