Learning objectives
At the end of this course the students should be able to:
- set up simple DC and AC circuits;
- carry out measurements of magnetic fields;
- use basic instrumentation for electtrical measurements (multimeters and oscilloscopes);
- discuss and analyze critically experimental results;
- write clear experimental reports.
Prerequisites
Laboratory of Physics 1.
Course unit content
Theoretical lectures and practicals about basic electrical circuits and electromagnetism.
Full programme
DC circuits: ideal and real generators, resistors. Instrumentation: oscilloscopes, digital and analog multimeters. Measurements of current, voltage, resistance and electromotive forces.
Time varying signals: periodic and non periodic. Noise. Inductance and Capacitance. Impedence. Fasors. RC and RL circuits. High-pass and low-pass filters. LCR series circuit: free and forced oscillations. LCR parallel circuit. Notch and Band pass filters. Active circuits: transistors and operational amplifiers. Transformers. Measurements of self-inductance and mutual inductance. Transmission lines. Production and measurements of magnetic fields in multilayer coils: single coil and Helmoltz pair in series (to produce a spatially homogeneous magnetic field) and series opposition ( to produce a spatially homogeneous magnetic field gradient).
Bibliography
Detailed lecture notes will be made available before the lectures via the software Elly.
Teaching methods
Lectures will include a brief introduction on the relevant theory followed by experimental work. Audio/video content will be mae available on Elly for those students who will not be able to attend live. Students will be divided in groups of 3 to carry out the experiments and write the experimental reports. Instructions for the experiment will be given in the lecture notes, together with the relevant theory. The lecture notes will be uploaded in Elly at the beginning of the course and will cover every aspect of the course. The lecturer will provide support and supervision at all times during laboratory sessions.Lecture notes will be discussed and made available to the students before the lectures, using the Elly software.
Assessment methods and criteria
The progress of the students along the guidelines will be evaluated through:
- close supervision of the students activity during the laboratory lessons;
- the weekly correction and discussion of the written experimental reports;
- a final oral exam.
The final marks will determined by attendance and attitude during lectures and practicals (25%) and by the final oral exam (75%).
