FCE Набор для изучения электрических полей




The Electric Fields Study Set, "FCE", allows the spatial study of the electric field in all its dimensions: calculation of the intensity, force lines, equipotential surfaces in both static and dynamic fields, giving the student a more extensive spatial vision not given by other methods.

The supply of spheres, cylinders, wires and conducting planes together with charge sources allows the student to study experimentally Coulomb's law, the electric force between conducting spheres, Gauss's theorem and the principle of superposition. The calculation of the electric flux allows us to, experimentally determine the redistribution of charges generated in plane-parallel capacitors in series and parallel configurations. The effects of dielectrics on capacitors will be carried out using different materials: wood, glass and plastic blocks, which allow us to study series/parallel configurations.

The "FCE" consists of a robot arm to which is connected a probe capable of measuring the static and dynamic electric field strength. The control software together with the data acquisition board allows to perform sweeps in space storing the electric field intensity point by point with a maximum resolution of 1 mm. The Set is supplied with a management software specially designed for the spatial representation of the electric field strength and lines of force.

The mathematical tools of integration and derivation available in the control software allow the experimental verification of the laws, theorems and basic principles of electricity that are rooted in the theoretical plane and that, through the FCE Set, can be transferred to the experimental plane.
