Answer . \nJust as the flow of water in a river constitutes a current of water, flow of charge, i.e. charges in motion constitue an electric current.\n- The charged partic…les whose flow in a definite direction constitutes the electric current are called current carriers.e.g. electrons in conductors,ions in electrolytes,electrons and holes in semiconductors. \nThe essential requirement for maintaining a steady current is a source of e.m.f.\ne.m.f. is associated with an arrangement or mechanism which can supply energy or does work to move the electric charge from lower potential energy to higher potential energy.
Current is basically, the rate of flow of charges through a conductor or wire. It is commonly denoted by the alphabet I and measured in Amperes. I = ne/t n = no of el…ectrons e = charge on an electron t = time taken for electron to move
One kind of electrical current is the movement of electrons. Electric currents are flows of the electrically charged particles found naturally within all conductors. Dur…ing an electric current in a wire or other metal object, the electrons of the metal atoms are forced to flow along. Other answers During currents in electrolytes, charged atoms called ions are flowing. In salt water, battery acid, wet earth, and human bodies, the ions found naturally in those materials are forced to flow. For example, an electric current in salt water is composed of positively charged sodium atoms moving in one direction, while negatively charged chlorine atoms go the other way. During currents in plasma, movable electrons are flowing one way while positively charged gas atoms go the other way. In electric sparks, neon signs, fluorescent lamps, and in plasma in outer space, most of the current is composed of moving electrons, but a tiny portion is caused by positive gas ions flowing backwards against the electron motion.
It has 5 watts.
Electric current is a flow of electric charge. In electric circuitsthe charge is carried by moving electrons in a wire.
Electricity current is the flow of charge.
DEFINATION: - electriccurrent is defined as the time rate of change of charge passingthrough a specified area the moving charge may be positive or negative;the area may b…ecross-sectional area of a wire or some other suitable spatial areawhere charge are in motion. expressed mathematically as - i=dq/dt in this equation i denote the instantaneous electric current and q denote the net charge,which may be the positive as well asnegative kind,that is, q = N1p+N2e where, N1p = total positive charge, N2e = total negative charge Voltege
Without electricity, your brain wouldnÃ¢??t work. Electricity isresponsible for the nervous system sending signals to the brain,for your brain telling your muscles to move, …and for synapsesfiring.
Yes, it has a slight amount of electricity to power up a lightbulb
Current is the flow of electrons from one atom to the next. Current is measured in amps.
If "dead" means brain dead then you've answered your own question, there is no activity left.
I like to use a water tower connected to a pipe as an example of how electricity works. Electricity depends on voltage AND current. If you think of it like a water supply the…n the voltage would be like the pressure in the pipes due to the height of the water tower. The current would be like the speed with which the water flows through the pipes and that is determined by the resistance, which we can think of as the size of the pipe. If we make the pipe bigger, that is, decrease the resistance, then the water flows faster. If we decrease the resistance in an electrical circuit then the current increases. That is why you often hear the term current used for both electricity and water flow. For more technical details please see my answer to the question about resistance. "If a fuse will melt.."
In metal conductors, electric current is the flow of electrons.
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 runthrough wires mostly to push …certain things. In a lightbulb, thecurrent is restrained and the energy created by the current isturned into heat and light energy. In a fan, the electric currentis used to turn the rotor which produces kinetic energy. Electric current is able to do tons of different things, and areused in most aspects of our daily life. Answer The original answer is quite wrong in suggesting that only a 'verystrong' electric current can kill you! In fact a current of just30-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!
Yes or No.I have no idea
