Why potential across pn junction is called potential barrier?
The potential across a pn junction is called potential barrier because majority charge carriers have to overcome this potential before crossing the junction.
Which is greater the breakdown voltage or the barrier potential?
Breakdown voltage is far greater than barrier potential. silicon:- break-down voltage :- 5v - 450 v barrier potential ;- 0.5v to 0.7 V
What are some potential hazards for children who experience inconsistent and unpredictable child care?
wet floors
Why can't the potential barrier of a diode be used as a voltage source?
The potential barrier of a diode is caused by the movement of electrons to create holes. The electrons and holes create a potential barrier, but as this voltage will not supply current, it cannot be used as a voltage source.
Why would it be important to do a background check on a potential day care provider?
Doing a background check on a potential day care provider is important to make sure the child is being taken care of by a competent caregiver with no felony convictions. It can also give a parent peace of mind to know the child is safe.
Compare the characteristics of a silicon and germanium diode?
Potential barrier of silicon is 0.7, whereas potential barrier of germanium is 0.3
What is the potential barrier of germanium?
0.3 volt
What happens to the barrier potential when the temperature increases?
barrier potential P0=(kT/q)*ln(Na*Nd/Ni^2) when T ↑, P0↑.
What happen to barrier potential when temperature increases?
barrier potential P0=(kT/q)*ln(Na*Nd/Ni^2) when T ↑, P0↑.
Potential hazard for children who experience inconsistent child care?
rape, sodomy, molest, fondle, diddling
Is barrier potential temperature dependent?
Yes, it varies inversely, i.e. as temperature increases the barrier potential decreases. It decreases by 2mV for degree Celsius rise of temperature.
What is non barrier crimes?
A "barrier crime" is one that makes one ineligible for employment in areas such as child care, elder care, domestic aid and shelter and others. In Virginia (and it may be different in other states), Code § 63.2-1719 defines a barrier crime as: "Offense" means a barrier crime and, in the case of child welfare agencies and foster and adoptive homes approved by child-placing agencies, (i) a conviction of any other felony not included in the definition of barrier crime unless five years have elapsed since conviction and (ii) a founded complaint of child abuse or neglect within or outside the Commonwealth. In the case of child welfare agencies and foster and adoptive homes approved by child-placing agencies, convictions shall include prior adult convictions and juvenile convictions or adjudications of delinquency based on a crime that would be a felony if committed by an adult within or outside the Commonwealth. In short, barrier crimes are those that prevent employment in certain care-giving occupations. See the references to the above in the Related Link below, Section 1719.
