The educational resource shows a visual about the relation between field intensity and potential: the work carried out by the field when a charged particle moves from one point to another, only depends on the potential at these two points and not the distance covered.

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.
