SDGs

This teaching activity contributes to the achievement of the Sustainable Development Goals of the UN 2030 Agenda.

Affordable and clean energy Industry, innovation and infrastructure

Academic Year 2018/2019

Learning outcomes

At the end of the course, the student knows the laws of kinetmatics and classical dynamics, the meaning of work and energy, and the foundations of classical electromagnetism. 

The student is able to solve basic physics problems and to apply the acquired physics knowledge to sensors and devices relevant for modern information technology.

Course contents

-) International System of Units of Measure: Time, Mass, Length and Charge

-) Velocity and acceleration. Newton's laws of motion.

-) Work and energy. Potential energy. Conservation of mechanical energy. Dissipation of energy by viscous forces. Equivalence between work and heat.

-) Electrostatics: Coulomb's law. Electric field and potential. Gauss' theorem. Motion of charges in electric fields. Electric capacitance.

-) Electric current and Ohm's law. Mobility and resistivity: conductors and insulators. Jule effect. Electric cirucits with resistors in series and in parallel. Kirchofff's laws. Capacitors in RC circuits: transient phenomena.

-) The magnetic field. Lorentz's force. Sources of magnetic field. Electromagnetic induction. Hall effect and magnetic field sensors. Application of electromagnetic induction.

-) Circuits in alternating current: reactance and impedance. Analysis of RLC, RC and RL circuits with phasors. Resonance condition. Filters.

-) Electromagnetic waves: properties, generation and detection. The photon: polarization and quantum behaviour.

Teaching methods

Frontal lectures with combined use of projected slides, video, and calculations the blackboard. Each lectures is complemented by application examples and exercises. Specific sessions will be devoted entirely to exercises in preparation of the exam.

Assessment methods

Written examination, in which the student must solve some physics problems on the course main contents. Students that pass the written examination may also sustain an oral examination, if they aim at improving their final score.

Teaching tools

Available on Insegnamenti OnLine:

-) Slidesof all lectures

-) Lecture notes 

-)  Physics problems (with solutions) in preparation to the written examination

-) MATLAB scripts (solution of physical problems and simple simulations of physical systems)

-) Physics problems (with solutions) assigned in the previous exams
