This is a characteristics of semiconductor diode {pn junction}.In forward biasing here we connect p to positive terminal and n -ve terminal when external voltage is aplied in such a direction that cancels out potential barrier thus permitting current
flow
In reverse biasing the connection of pn junction is inverted but in this the potential barrier incresesand offers resistance to current flow but at a certain voltage current increases suddenly(the break down voltage)the zener diode works in this principle
What else can I help you with?
What are the types of biasing in pn junction diode?
There are 2 type of biasing in PN junction didoe Forward biasing Reverse biasing
What effect of depletion layer by biasing?
on forward biasing width of the depletion layer decreases whereas on reverse biasing the width of depletion layer increases.
What happens in the depletion region in reverse bias?
in forward biasing depletion region width decreases and in reverse biasing it increases .
What is the forward biasing of a junction?
Forward biasing can be satisfied when a positive polarity of a battery connect with P side and the negative connect with N side In the P-N junction, that is caused : The free electrons in the N side will pushed by negative charge, and holes move far of positive charge, after that we will have a barrier (small area of barrier between P and N) this biasing called Forward biasing, because of small resistance of barrier, the current will flow, we can use it as a switch. the Reverse biasing is the opesit of all these specifications.
Does reverse biasing an LED for a period of time reduce its forward biased threshold voltage?
yes
What are the different types of biasing?
Fixed Bias,Self Bias, Forward Bias, Reverse Bias
How can electrons flow through base collector reversed biased region in transistors?
collector base is reverse biased (connect n region to be +ve terminal &p region to - ve terminal .due to forward biasing at emittor base juntion electrons follow from emittor to base .
How depletion region is narrowed during forward biasing?
When the pn junction is forward biased, some of the space charge is neutralized reducing the width of the pn junction.
Which biasing is known to as universal biasing?
voltage divider biasing
How biasing of FET differs from biasing of BJT?
in BJT forwardbiasing & reverse biasing are carried out but in FET voltage divider biasing &self biasing are carried out.
What is meant by biasing a diode?
Biasing a diode refers to the process of applying a voltage across its terminals to control its conductive state. Forward biasing occurs when the positive terminal of the voltage source is connected to the anode and the negative to the cathode, allowing current to flow through the diode. Conversely, reverse biasing connects the positive terminal to the cathode and the negative to the anode, preventing current flow. Proper biasing is essential for the diode to function effectively in circuits, such as rectifiers and signal modulation.
What is the relationship between chemical equilibrium and the rates of forward and reversed reaction?
The relationship between chemical equilibrium and the rates of forward and reversed reaction is they will both be equal. Meaning both of them will be just about the same.
