How to Use Capacitive Sensors to Help Solve Difficult Level
... Since capacitive sensors are used to sense liquids, any liquid touching the actual sensor will cause it to lock on. Because capacitive sensors cannot sense through metal, applications that require liquid level detection through a metal container wall require special sight glass and tank well fitting ...

... voltage. This quadrupling is untrue, because the two electric fields, one travelling to the right and the other to the left, have no relationship with each other. The reality is that each electric field contains energy u per unit length, totalling 2u, not 4u, of electric energy. The missing energy i ...

Dielectric
A dielectric material (dielectric for short) is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material as they do in a conductor, but only slightly shift from their average equilibrium positions causing dielectric polarization. Because of dielectric polarization, positive charges are displaced toward the field and negative charges shift in the opposite direction. This creates an internal electric field that reduces the overall field within the dielectric itself. If a dielectric is composed of weakly bonded molecules, those molecules not only become polarized, but also reorient so that their symmetry axes align to the field.The study of dielectric properties concerns storage and dissipation of electric and magnetic energy in materials. Dielectrics are important for explaining various phenomena in electronics, optics, and solid-state physics.
