Doped semiconductors: Electric neutral - an explanation
In solar cells often doped semiconductors are used. How do doped semiconductors In a doped semiconductor foreign atoms are introduced into the semiconductor artificially. Characterized a different conductivity is achieved. Frequently, as a semiconduc
Electrical pulse - an explanation of nerve conduction
Nerve cells conduct electrical Impule on. The nervous system of humans The nervous system is to a sophisticated system that allows the human body, to communicate and to feel. Through this system, people can taste, touch, see, smell and hear. The nerv
Why conducts saltwater electricity? - A simple explanation
Salt water is a good conductor of electricity. Saltwater - chemical terms Salt consists of Na-Cl molecules. Here go metallic sodium atoms, a so-called. Ionic bonding one with the chlorine atoms. Water in turn consists of a very specially constructed
How is electricity?
Electricity is produced when motion, light or chemical reactions, electrons are moving. That's power Before it comes to how electricity is created, you should be clear exactly what this is. An atom consists of a core which is electrically charged pos
What is neutrality? - A Definition
White is considered neutral color What is neutrality? The term neutrality comes from the term "neutral". This word comes from Latin and means something like "neither of them". In this country, the term usually is in the sense of "
How is a solar cell constructed? - Find out more on solar energy
Many German solar energy use already. s.media / Pixelio Operation of the solar cell To know is for you first that solar cells make up the photovoltaic effect advantage. The cells are constructed from treated semiconductor materials, which they can co
simply explained operation and circuit symbol - Diode in school
The diode makes current flow possible or prevents him. The circuit symbol of the diode and applications The circuit symbol of the diode is an equilateral triangle, on one tip, a vertical bar is. The triangle and the vertical bar symbolize the unilate
Fe2O3 and CO to CO2 and Fe in the Chemicals - Informative
This is a redox reaction. Oxidation numbers of Fe 2 O 3, CO, CO 2 and Fe If you believe in chemistry from the fact that all components are electrically neutral, so must any substance which releases electrons, one to be assigned, which receives the sa
Faster than the speed of light - is that possible?
The speed of light is too fast to be faster. The speed of light is the speed of propagation of light From movies and books you've probably heard the phrase "faster than the speed of light" belongs. This was according to Einstein the fastest way
Fluorescent Tube - the physics behind
How a fluorescent tube. Light in the gas produce - the principle of gas discharge The light of a fluorescent tube is not caused by the heating effect of electric current as the light bulb, but by moving electrical charges through the filler gas and b
What is a dipole molecule?
The water molecules is a known dipole molecule. In a dipole charges are unevenly distributed A (electric) dipole is in physics an arrangement with two equal but opposite electric charges. These two charges are isolated from each other at a small dist
What is a semiconductor? - An explanation
Semiconductors are particularly important for the computer art. When a body is not conducting and when Just look at it in two ways: A solid body conducts electricity or he does not. Or in other words: the body is an electrical conductor or an insulat
Electrical work - Definition and Explanation
When the stove heat is generated. Electrical work - definition made easy Electricity has energy and does work: He brings machines running, heat can produce (sometimes undesirable) and fluids - such as water or acids - decomposed by electrolysis. But
How to recognize a neutralizing? - Chemical explanations
Strong acids and bases give saltwater. Neutralization - chemical backgrounds Before it is shown how to recognize a neutralization, is to consider the processes in such a reaction of importance. At a neutralization reaction of two reactants are involv
Why passes hydrochloric electricity? - A detailed explanation
Many materials conduct electricity, but what makes it especially the hydrochloric acid? Lisa_Spreckelmeyer / Pixelio Electrical current Electric current is the flow of charged particles - electrons. Thus, the current can flow, a closed circuit must b
Phase voltage - an explanation
Without electricity, nothing works in today's society. So we switched a star connection Connect each connection of a coil with a different coil. These inputs denote with U2, V2 and W2. You have created a node or neutral. You can see this point as the
Use Electric spray gun correctly
Instead use a spray gun brush prefer With an electric spray gun doping is much easier than painting with a brush. In addition, a high area coverage is possible. The operation is very simple, so you learn to use quickly. To paint with an electrical sp
Electrical power sources - Instructions for use
Batteries are electrochemical elements. Electrical power sources to meet Electrical power sources you learn in physics classes in the theory of electricity. The operation can be easily illustrated by an experiment. Ask a zinc and a copper plate in a
What conducts electricity?
Copper conducts electricity very well. What it depends that a substance conducts electricity Whether a fabric passes the current or not depends on whether mobile charge carriers in the material are present. This can eg. As easily be bound electrons (
