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.

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).
Which of the following is a source of direct electric current?
Batteries
What devices have the ability to store current?
Batteries and capacitors store electric charge.
Does drift current depends on carrier concentration?
no,drift current depends upon electric field where as carrier concentration lead to diffusion current
What matter has the ability to carry an electric current?
An electrical conductor has the ability to carry an electric current. Most of the best conductors are metals such as copper. Water containing ions can also conduct an electric current (which lead-acid batteries rely on)
What are things like batteries which provide energy called?
Generators or storage devices for electric charge which they can release as a "flow of charge" called an "electric current".
What did the first battery do?
Basically the same as later batteries - store energy, and release it in form of an electric current.
How do you turn a battery operated water fountain into an electric one?
A BATTERY OPERATED FOUNTAIN IS AN ELECTRIC FOUNTAIN. IT IS NOT ALTERNATING CURRENT AS IN HOSEHOLD POWER, BUT DC CURRENT. There are many DC power supplies that will substitute for the batteries. The voltage necasary is determind by the motor requirment. Not a problem. The question is somewhat faulty. Are batteries not electric?
What is the definition of diffusion current?
Diffusion current is current that is generated due to the vibration of electrons.
What are three things that can run on direct current batteries?
flashlight toy car laser pointer electric wristwatch portable radio hiker's GPS walkie-talkie RC boat smartphone .mp3 player electric car Orthogonal configurators can only run on alternating current batteries. (That's why there are so few orthogonal configurators ... there is no such thing as alternating current batteries.)
What kind of current are most batteries?
Batteries are DC current.
What type of current will batteries provide?
Batteries are DC current.
