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.
Limiting current refers to the maximum current that can be passed through an electrochemical cell under specific conditions, such as when the rate of reaction is limited by the availability of reactants or by the kinetics of the reaction. Diffusion current, on the other hand, describes the movement of charged species due to concentration gradients in the electrolyte. It is a component of the total current in an electrochemical cell.

What is the formula of ilkovic equation in the diffusion current?
The Ilkovic equation for diffusion current is given by (i_d = nFAD), where: (i_d) is the diffusion current (n) is the number of electrons involved in the reaction (F) is Faraday's constant ([D]) is the concentration of the diffusing species (c) is the concentration of the species at a given distance (x) from the electrode
How does Counter current exchange affect diffusion?
Counter current exchange allows for a more efficient exchange of substances between two fluids by maintaining a concentration gradient along the exchange surface. This results in a greater rate of diffusion compared to simple diffusion. It also helps to conserve energy by minimizing the loss of substances from the gradient.
What is limiting current?
Limiting current refers to the maximum current that a circuit or device can handle without being damaged or operating improperly. It is usually specified in the device's datasheet or by the manufacturer to ensure safe operation and prevent overheating or other potential issues. Implementing current-limiting mechanisms like resistors or fuses can help protect the circuit from exceeding its maximum current rating.
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 there no flow of electric current between 2 objects of equal resistance?
I am not sure how the two objects of equal resistance are supposed to be connected. But for a current to flow, for example across a resistor, there must be a voltage difference between the terminals of this resistor.
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 definition of diffusion current?
Diffusion current is current that is generated due to the vibration of electrons.

What is the difference between total current assets and total current liabilities is?
the difference between total current assets and total liability is the working capital. It goes with a formula 'current asset -current liability =working capital '
Difference between electrical current and electrical charge?
current is the flow of charge.
What is produced first current or voltage?
current flows as a result of potential difference i.e. in a circuit if there is no voltage difference between two points, no current can flow between those two points. So voltage has to be produced first.
