if and anode
It should be noted that photoluminescence, due to `` Bremsstrahlung '' generated within the viewing screen by electron impact, appears to be important only if anode voltages in excess of 30 KV are utilized.
The anode should be removed and checked after 5 years ( sooner if there is a sodium based water softner inline ), and replaced if 15 cm ( 6 inches ) or more of bare wire is showing.
For example, if an electric field is placed across a solution of Na < sup >+</ sup > and Cl < sup >−</ sup > ( and conditions are right ) the sodium ions move towards the negative electrode ( cathode ), while the chloride ions move towards the positive electrode ( anode ).
The cathode supplies electrons to the positively charged cations which flow to it from the electrolyte ( even if the cell is galvanic, i. e., when the cathode is positive and therefore would be expected to repel the positively charged cations ; this is due to electrode potential relative to the electrolyte solution being different for the anode and cathode metal / electrolyte systems in a galvanic cell ).
Like a typical diode, there is a fixed anode and cathode in a Zener diode, but it will conduct current in the reverse direction ( electrons from anode to cathode ) if its breakdown voltage or " Zener voltage " is exceeded.
While it is almost impossible to prevent anode / cathode formation, if a non-conducting material covers the metal, contact with the electrolyte is not possible and corrosion will not occur.
By placing the molecules in wells in the gel and applying an electric field, the molecules will move through the matrix at different rates, determined largely by their mass when the charge to mass ratio ( Z ) of all species is uniform, toward the ( negatively charged ) cathode if positively charged or toward the ( positively charged ) anode if negatively charged.
Zinc coatings prevent corrosion of the protected metal by forming a physical barrier, and by acting as a sacrificial anode even if this barrier is damaged.
Ionic compounds, if molten or dissolved, can conduct electricity because the ions in these conditions are free to move and carry electrons between the anode and the cathode.
In a triode radio-frequency ( RF ) amplifier, if both the plate ( anode ) and grid are connected to resonant circuits tuned to the same frequency, stray capacitive coupling between the grid and the plate will cause the amplifier to go into oscillation if the stage gain is much more than unity.
In the example characteristic shown on the image, if an anode voltage V < sub > a </ sub > of 200 V and a grid voltage bias of-1 volt are selected, a plate ( anode ) current of 2. 25 mA will be present ( using the yellow curve on the graph ).
Now, if the input voltage amplitude ( at the grid ) changes from-1. 5 V to-0. 5 V ( difference of 1 V ), anode current will change from 1. 2 to 3. 3 mA ( see image ).
A second electrode, the anode or plate, will attract those electrons if it is at a more positive voltage.
In general, if the anode voltage exceeds the screen voltage, this region is avoided, and good performance can be expected.
Zinc is considered a reliable material, but is not suitable for use at higher temperatures, as it tends to passivate ( becomes less negative ); if this happens, current may cease to flow and the anode stops working.
One disadvantage of aluminium is that if it strikes a rusty surface, a large thermite spark may be generated, therefore its use is restricted in tanks where there may be explosive atmospheres and there is a risk of the anode falling.
For example, if a particular design shows that a pipeline long needs 10 anodes, then approximately one anode per kilometere would be more effective than putting all 10 anodes at one end or in the centre.
A thyristor can be switched off if the external circuit causes the anode to become negatively biased, a method known as natural, or line, commutation.
* Switch on dv / dt — the thyristor can be spuriously fired without trigger from the gate if the rate of rise of voltage anode to cathode is too great.

* Knowledge ark, a collection of knowledge preserved in such a way that future generations would have access to said knowledge if current means of access were lost
The standard example is the stock of a company, undervalued in the stock market, which is about to be the object of a takeover bid ; the price of the takeover will more truly reflect the value of the company, giving a large profit to those who bought at the current price — if the merger goes through as predicted.

Intuitively, if we placed a small paddle wheel there, the larger " current " on its right side would cause the paddlewheel to rotate clockwise, which corresponds to a curl in the negative z direction.
By contrast, if we look at a point on the left and placed a small paddle wheel there, the larger " current " on its left side would cause the paddlewheel to rotate counterclockwise, which corresponds to a curl in the positive z direction.
Pelton added " our strategy is to defend and protect our current markets while investing in products and services to secure our future, but we can do this only if we succeed in restructuring our processes and reducing our costs.
