Practical 1.- Basic Instrumentation and passive components.
The first practical is a brief introduction of the main laboratory instruments with which the student will have to work when performing the generation and measurement of a given electrical quantity. They have to become familiar with the use of the laboratory equipment. A brief description of their main functions and different modes of operation will be provided in this practical. The student must himself practice with the equipment to acquire the necessary skills in handling.
Practical 2.- Current and voltage dividers, variable resistors.
This practical session aims to enhance understanding of series and parallel configurations of resistors while helping students to acquire practical skills in assembling circuits and use the meter as a measuring instrument. A new component is also introduced, the trimmer, working as a voltage divider and current divisor in a coupling network. In the development of the practice, the student will have an opportunity to check the laws of Kirchhoff lectured during the theory sessions. The analysis capability to estimate a priori the expected results is expected. Drawing conclusions and thinking about them may help to self-correct misconceptions
Practical 3.- Experimental characterization of voltages and currents.
In this practical the student is introduced to the practical study of the diode, LED diode and Zener diode. In order to study them different measurements and representations aimed at observing the behavior of a rectifier diode, diode LED and Zener diode will be made. The student will measure and represent voltage/current curve of a diode, LED diode and Zener diode.
Practical 4.- Theorems.
Through this practical the student will be able to verify and manage techniques derived from Kirchoff's laws and Ohm's law that introduce a simpler way to solve certain types of circuits.
Practical 5.- Dependent Sources.
In this laboratory session the circuit simulation program PSpice is used to analyze circuits with dependent sources
Practical 6.- Transient Circuits.
In this laboratory session, students will analyze and solve transient circuits in the time domain from three possible approaches: theory, simulation and experimental using the protoboard.
Practical 7.- Analysis of Circuits in Sinusoidal Steady Regime.
In this laboratory session, students will review the concepts studied in the theory lesson to be able to solve problems by applying sinusoidally excited circuits translations between the domains of time and frequency. A PSPICE simulation of a circuit in sinusoidal steady state will be performed to evaluate the response of the circuit elements or the transfer function. Finally, the phase difference between signals by mounting the protoboard and using the oscilloscope will be measured.
Promoting the continuous improvement of working and study conditions of the entire university community is one the basic principles and goals of the Universidad Politécnica de Cartagena. Such commitment to prevention and the responsibilities arising from it concern all realms of the university: governing bodies, management team, teaching and research staff, administrative and service staff and students. The UPCT Service of Occupational Hazards (Servicio de Prevención de Riesgos Laborales de la UPCT) has published a "Risk Prevention Manual for new students" (Manual de acogida al estudiante en materia de prevención de riesgos), which may be downloaded from the e-learning platform ("Aula Virtual"), with instructions and recommendations on how to act properly, from the point of view of prevention (safety, ergonomics, etc.), when developing any type of activity at the University. You will also find recommendations on how to proceed in an emergency or if an incident occurs. Particularly when carrying out training practices in laboratories, workshops or field work, you must follow all your teacher's instructions, because he/she is the person responsible for your safety and health during practice performance. Feel free to ask any questions you may have and do not put your safety or that of your classmates at risk.

Additional comments:
If a student who has passed an evaluation activity in the continuous evaluation system, wants to submit to that same activity in the final evaluation system must waive the grade obtained in the continuous evaluation system.
Any of the assessment instruments outlined, may be established or required to be developed fully or partially in English in written form, in response to the evaluation of the Ta4 competence.
Attendance to practices is not mandatory. However, attendance at all practices will be recorded in the control and monitoring mechanisms (see section 7.2) and may be considered as an additional merit.
Likewise, the participation and satisfactory performance of activities that the lecturer may propose may be considered as additional merit
Any additional merit can be taken into account as a credential before an eventual upward revision process on the overall mark of the subject whose provisional score is 5% below the lower limit of the next section:
D: [ 0%, 50%[
C: [50%, 70%[
