diode is unipolar

I don't think that the pn junction diode can emit light. Maybe it does, but a 'plastic' that covering the diode makes the light cannot be seen. Besides, you won't see it glow as it connect to the power source, right?
n-p-n and p-n-p junction diodes
what is the difference between reverse characteristics of zener diode and a practical diode ?

PN is pressure rating of pipe. the number gives you the resistance against pressure. ın that case it is 10 bar.

As a title it means Practical Nurse.
PN means pressure rating of a pipe....PN is just a symbolic representation....
.pn was created in 1997.

Will the valve DN, PN, respectively, what does this mean? PN name (pressure nominal) on behalf of Nominal pressure Units are MPa MPa For example, is J41H-16C Nominal pressure 16Kgf/cm2 Per square centimeter pressure value MPa 16Kg count if the case is PN1.6MPa The representative of the internal pipe diameter DN Units are mm mm DN50 example is the 50 mm
Pressure Nominal 40; 40 bar pressure rating for European flange
Given an infinitely convergent sequence pn with limit p, the forward difference is the measure of the difference between the current term and he next. The backward difference is the measure of the difference between the current term and the previous.i.e.forward difference: Δpn=pn+1 - pnbackward difference: ∇pn=pn - pn-1Also, note that since they are both expressed by pn, the forward difference is recognised by the use of a delta before the pn, and the backward difference by the use of a nabla.
PN is a short term for "pressure rating of a pipe" PN depends on wall thickness, diameter and material type. A PN 16 pipe is one that can withstand 16 bar (1.6 megapascals or about 232 psi) at 20 degrees c. If you want it interms of height of equivalent water column, 1 bar =10.2 m of height water column at 20 deg C, this a PN 16 pipe can withstand 16*10.2=163.2 m of water head (static+dynamic).
