Fisica per scienze e ingegneria vol.2 di Raymond A. Serway, John W. Jewett - Educational objectives
- The goal of the course is to provide the student with the ability to analyze and understand the main physical phenomena related to the electric and magnetic properties of matter.
- Prerequisites
- Knowledge of basic mathematical concepts and tools such as complex numbers, integration, derivation, differential and vector calculus.
- Teaching methods
- The course includes both lectures and practical classes.
- Other information
- Further information available on the Unistudium page (www.unistudium.unipg.it)
- Learning verification modality
- The exam consists of a written test and an optional oral test. The student obtaining a score higher than 18/30, could demand for an oral test in order to improve his evaluation.
