In a reactor where electrochemistry is being conducted and electron exchange is taking place, the ions around a given electrode will permit a rapid initial electron current. But what happens after a few moments and the initial "rush" to the electrode is over? It's the ability of ions to diffuse through the electrolyte and get next to the electrode to continue the reaction that will govern the rate at which it preceeds. That sets the limiting current. Limiting current is the current flowing "out" or "in" an electrode in a reactor after the reaction begins and ion mobility takes control of the rate or speed of the reaction.

∙ 16y agoCurrent limiting is what we do to prevent "runaway" current in a circuit. The current limiting component or components act to prevent "overcurrent" in a given situation. There are a number of examples, so let's pick one or two. On the repair bench of a technician, there might be a variable voltage power supply to permit the testing of stuff. Some of these supplies have built in current limiting. The technician can set an appropriate amount of current, and if "something goes wrong" in a test, the power supply's current limiting circuit crowbars the power off at the preset limit. A fuse or circuit breaker is a current limiting device. About the only difference is that the latter can be reset, while the former must be replaced.

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.
How much current will flow in service wire?
In a service drop conductor the only limiting factor is the first over current device down stream from the service.
Why is the term limiting used to describe the limiting reactant?
The term "limiting" is used because the limiting reactant limits the amount of product produced.
What are some limiting factors of a sloth?
A limiting factor is outside the rainforest for it is to slow
What determines the effect of a limiting reagent on the mass of product?
the amount of limiting reagent
Advantage of current limiting?
Current limiting is the practice in electrical or electronic circuits of imposing an upper limit on the current. The simplest form of current limiting in mains is fuse.
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.
A component used to protect an led in a circuit?
you could use a current limiting diode such as a Zenner, or a current limiting resistor in series with the LED
What does a risitor do?
it is used for limiting current or dropping voltage.
What is a slc500?
A current limiting resistor for ac devices.
How do you size a current limiting reactor for a capacitor bank?
P=ie
Where do you use the current limiting resistor?
in a flashing led circuit connected in series
Is there a filter that can decrease the brightness of a bulb?
A: It is not a filter but rather a limiting resistor for the current.
What is the meaning of CLE?
CLE has various meaning. One of it is Current-limiting element.
What is ELSP?
An ELSP is a current limiting fuse used in series with the primary fuse of a transformer.
Is a zener diode a current limiter?
No. A zener diode is a voltage limiter. Circuit design might create a current limiting response, but the basic control is voltage, not current.
How does a resister pack work?
resister is nothing but a 'clay' which will reduce the flow of current. There by limiting the volt.
