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.

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.
