Chemical changes, change in magnetic flux linked with a conductor cause the production of electric current.
The electric current supplied to most homes is alternating current (AC).
An electric discharge through neon gas gives a reddish-orange glow which is most commonly used in advertising signs and lamps.
In most cases, chemical energy stored in the battery produces the electric current. Rechargeable batteries are capable of taking electric currents and using them to reverse the chemical reactions, thus gaining more chemical energy that can be used readily.
This depends upon the application. For most home appliances and industrial machinery, alternating current is the best electric current. In most computer electronics, alternating current must be converted into direct current.
An electric stove uses Alternating Current to operate.
The voltage needed to produce a current that can be felt varies from person to person, but typically a voltage above 10 milliamperes can be felt by most individuals. Keep in mind that electrical current can be dangerous, and it is not recommended to intentionally expose oneself to electric shocks.
Electrons are mostdirectlyrelated to electric current. (Electric current is caused by the movement of electrons between atoms.)
Electric current flows in conducting materials such as metals. The best conductor of electric current is silver, followed closely by copper and then aluminium.
I is the international (SI) symbol for electrical current.
Electric current is the movement of charge around a circuit and so cannot really be stored, however, the energy which it carries is stored in most things.
They can kill you.Yes, electric currents can kill you, but only if it is very strong. Electric current can do many things. Electric current is run through wires mostly to push certain things. In a lightbulb, the current is restrained and the energy created by the current is turned into heat and light energy. In a fan, the electric current is used to turn the rotor which produces kinetic energy.Electric current is able to do tons of different things, and are used in most aspects of our daily life.AnswerThe original answer is quite wrong in suggesting that only a 'very strong' electric current can kill you! In fact a current of just 30-odd milliamperes will kill you. This is a very small current (e.g. a 60-W /230-V lamp draw a current of 260 mA!
Answerits lightning, for a more simple answer......electric current flow is the movement of charges. Most often, however, we consider electric current flow to be moving electrons, or electron current flow.We most often use the term electric current flow to refer to the moving electrons, the flow of which is measured in amperes.Earlier scientists, before the discovery of electron, do believe that current flows right from positive terminal to the negative. This is known as conventional current flow.So electron flow is always opposite the direction of conventional current.
