In an electrode-electrolyte circuit what do the terms drift current and diffusion current mean?
A drift current is electric charges being moved in the presence of an electric field, and a diffusion current is electric charges being moved by a chemical diffusion gradient (where no electric field exists, but where there is a concentration gradient of chemical species driving the current).
Is a light bulb a chemical or physical change?
A light bulb is not a change in and of itself but the process by which it gives off light is physical. While an electric current causes a given component of the bulb to glow (it may be the filament of an incandescent bulb or the vapor in a fluorescent one), but that substance does not change its chemical identity.
Device that produces an electric current by converting chemical energy into electrical energy?
battery
What uses a chemical reaction to create an electric current?
An electrochemical cell, which is sometimes called a battery.
Which type of chemical reaction takes place when electric current is passed through water?
The process is called electrolysis, and it usually results in a decomposition reaction. For example, passing an electric current through water results in the reaction 2H2O --> 2H2 + O2.
What are some methods for decomposing compounds?
thermal decomposition: decomposing by the means of heatelectric decompostion: decomposing by sending a electric current through the compoundthere are some mor e but these are all i know
Is the heating element on a stove a chemical reaction?
No. It is a physical process cause be passing an electric current through a wire.
What role does electric current play in a megnetic levitating trian?
The role electric current plays in is the physical and chemical stages. No only does the current provide the use of elctricity and the mocement of atoms but its also used as a scientific research. Its an mass linking into a atom.
What are the effects of electric current?
current has five effects. 1. physical effects 2. xray effects 3. heating effects 4. chemical effects 5.magnetic effects.
Is a filament of a light bulb glows when an electric current flows through it is a chemical change?
It is a physical change brought about by the exitation of molecules producing heat and light. A general rule of thumb is that a physical change can be repeated on an article and chemical change cannot. Remove the current from a filament and it is still a filament.
In an electrode-electrolyte circuit what do the terms drift current and diffusion current mean?
A drift current is electric charges being moved in the presence of an electric field, and a diffusion current is electric charges being moved by a chemical diffusion gradient (where no electric field exists, but where there is a concentration gradient of chemical species driving the current).
What is the role of electrical force in chemical reaction?
The passage of an electric current through a conducting liquid causes chemical reactions.The resulting effects are called chemical effects of electric current
What most occur to produce electric current?
Chemical changes, change in magnetic flux linked with a conductor cause the production of electric current.
What physical quantity corresponds to the rate of flow of charge?
Electric current
What kind of energy is stored in a battery can be used to produce electric current?
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.
What is the meaning of fuelcell?
it is a type of electro chemical cell that is able to fuel into electric current , it is able to do it through reaction between oxidized particles and electric current
