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.
What else can I help you with?
Does drift current depends on carrier concentration?
no,drift current depends upon electric field where as carrier concentration lead to diffusion current
How did the voltage e?
It seems your question was cut off. If you were asking how voltage is generated or influenced in a specific context (such as in electrical circuits, batteries, or power systems), please provide more details for a more tailored response. Generally, voltage, or electric potential difference, is created by the separation of charges and can be influenced by factors like resistance, current, and electromagnetic fields.
What is Another name for DC current?
Another name for DC current is direct current. It refers to the flow of electric charge in a single direction, as opposed to alternating current (AC), where the flow of charge periodically reverses direction. DC current is commonly used in batteries and electronic devices.
What is definition of diffusion current?
The diffusion current in a metal-semiconductor diode is derived based on the assumption that the depletion layer is large compared to the mean free path, so that the concepts of drift and diffusion are valid.
The flow of electric charges is called?
The flow of electric charges is current.
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 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 process by which an electric current is produced?
An electric current is produced through a process called electromotive force (EMF), which can be generated by batteries, generators, or solar cells. When a circuit is closed, the EMF causes the flow of electric charge, resulting in 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 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 did the first battery do?
Basically the same as later batteries - store energy, and release it in form of an electric current.
What controls the flow of current with an electric field?
The flow of current in a material is controlled by its conductivity, which is influenced by the presence of an electric field. When an electric field is applied, it can cause charged particles in the material to move, resulting in the flow of current. The conductivity of the material determines how easily current can flow in response to the electric field.
What generate current?
Current is generated by the flow of electric charge in a circuit. This flow can be created by sources such as batteries, generators, solar panels, or power plants. The movement of electrons through a conductor produces an electric current.
What is the definition of diffusion current?
Diffusion current is current that is generated due to the vibration of electrons.
What are 3 examples of electrical energy?
. lightning . batteries . energy generated by electric eels
What type of current will batteries provide?
Batteries are DC current.
