The main objective of this OER is to discover how electricity works and how it is obtained, as well as the development of electrical circuits for its use and distribution, through practical work and research into the sources offered. The learning situation is set out in the form of tasks in which the student: Learn the contents of electricity generation and the components of an electrical circuit. Putting it into practice with the creation of one. Research using the digital resources provided

The transformer modifies the voltage of a current.

The educational resource shows a visual about the movement of electric charges: the visual shows a capacitor where the intensity of an electric field bewteen its plates is practically constant. This area is a good place to study how the charges inside an electric field move.

When an electric current of variable intensity circulates through a coil an induced current originates inside it.

Type of electronic test instrument that allows observation of varying signal voltages, usually as a two-dimensional plot of one or more signals as a function of time.

This visual shows you how to insert an ammeter and how to use it in a circuit.

In this teaching unit you will learn: To describe qualitatively the phenomena of electrification, electrostatic attraction and repulsion and to introduce the concepts of electric charge, insulators and conductors. To justify Coulomb's law and use it to calculate the force exerted by one or two charged particles on another. To intensity and calculate its value in the case of one or two charged particles. To describe the electric field using force lines. To justify the concepts of potential ele...

In this teaching unit you will learn: To understand the parallelism between an electric circuit and the distribution of water in a closed circuit. To learn the characteristic magnitudes which describe an electric circuit: the potential difference, intensity, resistance, electromotive and counter electromotive force. To demonstrate and understand the fundamental laws which relate these magnitudes. To be able to calculate intensities, tension, power and energy in simple circuits.
