If a similar ball is charged by the same glass rod, it is found to repel the first: Two balls that are charged with a rubbed amber rod also repel each other. However, if one ball is charged by the glass rod, and the other by an amber rod, the two balls are found to attract each other. These phenomena were investigated in the late eighteenth century by Charles-Augustin de Coulombwho deduced that charge manifests itself in two opposing forms.

This discovery led to the well-known axiom: The magnitude of the electromagnetic force, whether attractive or repulsive, is given by Coulomb's lawwhich relates the force to the product of the charges and has an inverse-square relation to the distance between them.

Electric charge gives rise to and interacts with the electromagnetic forceone of the four fundamental forces of nature. The most familiar carriers of electrical charge are the electron and proton. Experiment has shown charge to be a conserved quantitythat is, the net charge within an electrically isolated system will always remain constant regardless of any changes taking place within that system.

The charge on electrons and protons is opposite in sign, hence an amount of charge may be expressed as being either negative or positive. By convention, the charge carried by electrons is deemed negative, and that by protons positive, a custom that originated with the work of Benjamin Franklin.

Charge is possessed not just by matterbut also by antimattereach antiparticle bearing an equal and opposite charge to its corresponding particle.

Electric current The movement of electric charge is known as an electric currentthe intensity of which is usually measured in amperes.

Current can consist of any moving charged particles; most commonly these are electrons, but any charge in motion constitutes a current. Electric current can flow through some things, electrical conductorsbut will not flow through an electrical insulator.

Current defined in this manner is called conventional current. The motion of negatively charged electrons around an electric circuitone of the most familiar forms of current, is thus deemed positive in the opposite direction to that of the electrons. The positive-to-negative convention is widely used to simplify this situation.

An electric arc provides an energetic demonstration of electric current The process by which electric current passes through a material is termed electrical conductionand its nature varies with that of the charged particles and the material through which they are travelling.

Examples of electric currents include metallic conduction, where electrons flow through a conductor such as metal, and electrolysiswhere ions charged atoms flow through liquids, or through plasmas such as electrical sparks.

Electric Field Lines Lab organized all parts of the lab report. Data section includes at least six electric field line diagrams – for a positive charge, a negative charge. September 11, Thirteen years ago, it was September 11, It was a beautiful, sunny day. But it was a day many people will always re member because of something that happened that morning. Four airplanes were hijacked. When spiders sense an electric field, they stick their spinnerets into the air and release silk. Called “tiptoeing,” this means spiders are ready for take-off.

While the particles themselves can move quite slowly, sometimes with an average drift velocity only fractions of a millimetre per second, [27]: That water could be decomposed by the current from a voltaic pile was discovered by Nicholson and Carlisle ina process now known as electrolysis.

Their work was greatly expanded upon by Michael Faraday in Current through a resistance causes localised heating, an effect James Prescott Joule studied mathematically in Early Electric Motors.

ELECTION RESULTS:

Physics is a natural science that involves the study of matter and its motion, along with related concepts such as energy and force. More broadly, it is the general analysis of nature. Our Instruments help the students to study Physics lab Experiments in a friendly way.

We are Manufacturer of Physics lab Equipments. our Physics Lab Equipments supplies in colleges, School. Electron-hole pairs are also being thermally generated in both p and n regions with a probability of, where is the energy gap between the valence and conduction bands.

The electric field, mentioned above, will cause the holes in the n-side to flow towards the p-side and electrons from the p- to the n-side. The Purdue University Online Writing Lab serves writers from around the world and the Purdue University Writing Lab helps writers on Purdue's campus.

An electric current is a flow of electric charge.: 2 In electric circuits this charge is often carried by moving electrons in a kaja-net.com can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas ()..

The SI unit for measuring an electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second.
