Objectives and Contextualisation
1. To describe the vectorial nature of the electric field and its relation with the scalar potential.

Methodology
Guided activities:
- Basis Theory: The lecturer will give the basic concepts in each chapter, in an ordered way, providing the
needed written material and the indications for complementing the study with the bibliography and other
resources (preferably virtual). The classroom classes will be devoted mainly to solving the doubts and to the
orientation in the study of the most relevant aspects of the subject.
- Problem lectures: The problems lecturers will explain, and provide the needed material, on how to solve the
typical problems of each part. Also, they will provide the necessary material and/or indications for completing
the study with the bibliography and extra resources (preferably virtual). The classroom classes will be devoted
mainly to solving doubts and emphasizing the key points in the problem-solving process.
- Laboratory work: Several practices will be done during the course. They could be made at the faculty labs.
Supervised activities:
- Personal (small group) work: During the students' attention time, the lecturers will be available to solve
individual questions.
Autonomous activities:
- Preparation of lectures: Students have to prepare the lectures, by checking the virtual campus for the provided
material.
- Preparation of practice work: Students have to prepare the practice work, follow the indications, and
do the tasks that will be given on the virtual campus.
- Solving problems: Students have to solve the problems of the list given by the lecturers, independently of
the problem classes done. The classroom classes will be used basically for solving the doubts that could have
emerged and to indicate the key points in the resolution.
- Study and preparation of exams: Personal work of the student to acquire the theoretical concepts as well
as the ability to solve problems.
-Preparation of the lab reports: By groups, the students will have to draw up the reports of the different practicals.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment
Continuous Assessment:
The final mark of the course will be obtained using the following proportions:
- 1st Partial Exam --> 40%
- 2nd Partial Exam --> 40%
- Laboratory reports --> 20%
- Delivered activities --> These can help to increase the grade of the partial exams.
Single Assessment
Students who opt for the single assessment will have to take two exams corresponding to the partial exams (each one will have a weight of 40%) on the day on which the continuous assessment students take the Partial 2 exam. On the same day, at the end of these exams, they will have to hand in the reports of the practicals carried out (with a weight of 20%) and the resolution of the problems of the deliveries (these are voluntary and will allow the improvement of the mark of the mid-term exams). In the case of single assessment students, both the practical reports and the deliveries must be done individually.
Both single and continuous assessment students will pass the course if the mark obtained by applying the different percentages is equal to or higher than 5.0 (out of 10). However, in order to be able to apply these percentages it is necessary that the mark (out of 10) of each of the partial exams is equal to or higher than 3.5 and that all the laboratory practicals, which are compulsory for all students, have been completed. In the case that in one or both of the two partial exams the mark is lower than 3.5, the student will have to take the retaking exam of the failed part with a mark lower than 3.5. Both in the single assessment and in the continuous assessment the recovery process will be the same, but in each case, the specific date will be the one foreseen by the coordination of the degree. The retaking exam will consist of a retaking exam for Partial 1 and another for Partial 2. The mark of the retake exam will replace the mark of the corresponding partial exam.
The laboratory reports and the problems of the deliveries cannot be retaken.
UAB Regulations: To be able to retake partial exams, the student must have previously been evaluated in a set of activities the weight of which is equivalent to a minimum of two-third parts of the total qualification of the subject. Students who have been evaluated only 1/3 or less of the total subject will be considered "Not Evaluable".
UAB Regulations: In the event that the student realizes any irregularity that might lead to a significant variation in the qualification of some evaluation activity, he or she will qualify with 0 for this evaluation activity, irrespective of the disciplinary process that could be started. If there are several irregularities in the evaluation of the same subject, the final qualification of this subject will be 0. Any plagiarism (total or partial), copying or attempted copying, letting oneself be copied, etc., in any of the evaluable activities will be considered "irregularities leading to a significant variation in the qualification".
