What is the reason for reverse saturation current?
its simple.reverse saturation current is because of the flow of minority carriers across the junction when the bias is changed suddenly from forward to reverse.this is why it doesnt depend on forward bias
What is the current?
Current is defined to be a flow of electrically charged carriers. These are usually electrons or electron-deficient atoms. It is symbolized by uppercase letter I.
Why there is no current in reverse bias condition?
Current flows in a reverse biased diode because diodes are not ideal. They do have leakage current and a breakdown voltage in reverse, just as they have a breakdown current in forward and a non-linear and non-parallel forward voltage to current curve. It is also possible that you are looking at a zener diode. A zener diode is specifically design to conduct at a certain voltage in reverse.
Do electrons really flow when current flows?
That means that there is actually something - the electrons - flowing in the specified direction. On the other hand, the "conventional current" is defined as the equivalent flow of positive charge. In the case that the charge carriers are negative (such as electrons), the conventional current flows in the opposite direction to the actual movement of charges.
What is meant by reverse saturation current?
reverse saturation current is produced by the thermal activity of the diode materials. This current: 1- Is temprature dependant; that is, it increases as temprature. 2- Accounts fot the major portion of diode reverse current surface leakage current is produced by contamination on the surface of the device, allowing current flow to bypass the junction
Voltage is pressure and current is flow what opposes flow?
Reverse current.

Why the negative half cycle cannot pass through the diode?
When the diode is reverse biased a depletion zone is formed at the junction between the cathode and anode, that lacks current carriers (it has neither electrons or holes). Without current carriers, the diode acts as an open circuit, blocking current flow.
What current that does not reverse its direction of flow?
direct current
Is a electric current a flow of electricity?
The flow of electrons from a body at a higher voltage to one at a lower voltage is flow of current.
How does a electric current flow through a circuit?
If a voltage is applied, electrons (or other charge carriers) are subjected to an attraction towards one side, and a repulsion from the opposite side. This results in the current, i.e., the flow of charge carriers.
Why bjt is a minority carrier device?
Although a small part of the transistor current is due to the flow of majority carriers, most of the transistor current is due to the flow of minority carriers and so BJTs are classified as 'minority-carrier' devices.
Does diode flow current in reverse bias?
Diodes will have a small leakage current in reverse bias. In most cases, this current can be considered insignificant and ignored.
How does voltage cause current to do work?
A voltage will cause electrons or other charge carriers to flow (if there is a path through which they can flow). In other words, it will cause a current.

What is Reverse Saturation Current of a diode?
When a diode is operated as reverse bias the current flow is almost completely blocked. A small amount of current is still able to travel in reverse through the diode and this is referred to as the reverse current saturation.
A grounding wire allows the movement of electrons in which direction?
Electrons flow from the negative terminal to the positive. Conventional current or simply current, behaves as if positive charge carriers cause current flow. Conventional current flows from the positive terminal to the negative
