What is the definition for diffusion?
Diffusion is one type of passive transport. In Diffusion, molecules move from a higher concentration gradient to a lower concentration gradient. Diffustion does NOT need energy, or ATP.Q: What is the DEFINITION of DIFFUSION?A: Diffusion- a type of passive transport in cells in which molecules move from areas where there are more of them to areas there are fewer of them.ur wlcm (: SnazzyChazzy
Does drift current depends on carrier concentration?
no,drift current depends upon electric field where as carrier concentration lead to diffusion current
Why is the current in diodes only due to diffusion and not influenced by electric field of batteries?
In diodes there are two types of current namely diffusion and drift current. Former one is due to concentration gradient of majority carriers (hole in p side n electron in n-side). Due to this difference of concentration of carriers majority carrier start to diffuse in other side. The amount of diffusion is just depends on concentration. Contrast to this, drift current which is very small in compare to diffusion current depends on the applied voltage across the diode. Since total current is mainly due to diffusion in forward biased hence it is not too much effected by battery's electric field. I dint know that batteries have electric field. INTERESTING.
Definition of ac machine?
A machine that runs on an alternating current.
Definition of current development of multimedia?
The definition of current development of multimedia involves the different content forms. These forms include a combination of video, audio, text, still images, and animation.
What is the definition of diffusion current?
Diffusion current is current that is generated due to the vibration of electrons.
What is the definition of contagious diffusion?
Contagious diffusion is a branch of expansion diffusion. It refers to a cultural trait spreading across a population like a disease.
Can diffusion current and drift current can exist in a Semi conductors?
Yes.

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 definition of diffusion in scientific terms?
Diffusion refers to the process by which molecules intermingle as a result of their Kineti energy of random motion
What is the difference between limiting current and diffusion current?
The limiting current is defined as the limiting value of a current that is approached as the rate of charge-transfer to an electrode is increased. The diffusion current is defined as a current in a semiconductor caused by the diffusion of holes and/or electrons.
What is the definition for the word diffusion?
Diffusion refers to the process of a substance spreading out to fill the available space. It occurs due to the random movement of particles.
What is the definition of hierarchical diffusion?
Hierarchical diffusion is the spread of a feature or trend from one key person or node of authority or power to other persons or places.
What is polarogram?
It is a plot of diffusion current as a function of varying potential or, a plot of current against applied voltage.
Does diffusion diffusion use energy?
No, diffusion does not use energy because it is a form of passive transport. The definition (if anybody needs it) is the movement of molecules in a fluid or gas from a region of higher concentration to a region of lower concentration.
What is the meaning of channel diffusion?
The scientific meaning of diffusion is when the particles separate/spread out
