To enhance our knowledge on rc helicopter capacitors and more, it is important to focus on two circuits to build or simulate real and virtual laboratory test. Keep learning electronic supplementary. This block PN in principle, allows the establishment of an electric current between its terminals, since the depletion zone is on top. However, if you apply a positive voltage at the anode, they generate an electric field that "pushes" the holes towards the junction, causing a narrowing of the depletion zone. Find out how to change and modify settings. If the applied voltage exceeds the barrier depletion zone disappears and the diode conducts. Under the action of a voltage greater than the barrier there may be some modifications. Remember that electrons and holes are directed to the union. At the junction they may recombine. This means that polarize a PN diode directive applies a positive voltage to the P and refusal to zone N. A PN diode conducts when it is directly polarized because the depletion zone is flooded with moving loads. The applied rc helicopter system voltage is used to overcome the potential barrier and move the charge carriers. Contrary to the above, by applying a positive voltage to the N and P negative area, remove the majority carriers near the junction. These carriers are attracted to the contacts increasing the width of the depletion zone. This makes the current due to majority carriers becomes zero. However, in both areas P and N is minority carriers (which are generated naturally in the material). A reverse biased diode is directly to the minority, who are attracted to the union. The movement of these minority carriers also creates a common, albeit much lower than that obtained for the same bias voltage levels. By increasing the reverse rc helicopter voltage, there comes a time when rupture occurs in the area of ??depletion, as occurs in an insulating material: the electric field can be so high that electrons start forming covalent bonds between silicon atoms, causing an avalanche fracture process. (Note: However, this does not necessarily mean the destruction of the diode, while the power consumed by the same will remain limited). The real voltage-current characteristic is easy to note. Keep in mind that this rc helicopter process happens instantly the moment you come in contact zones N and P, and requires no energy input other than that of thermal agitation produced by Brownian motion and diffusion triggers.
