The current then flowing is the of the FET . These can be purchased with this connection already made and in this case the devices are called current regulator diodes or constant current diodes or current limiting diodes ( CLD ).

Current limiting for Q20 is performed in the voltage gain stage : Q22 senses the voltage across Q19's emitter resistor ( 50 & Omega; ); as it turns on, it diminishes the drive current to Q15 base.
33.
Without current limiting the dissipation would be greater than 300 W ! ! ( 3 )-so limiting does have a benefit, but it turns out that the pass-transistor must now be capable of dissipating at least 60 W.
34.
Charging ports, however, can immediately supply up to at least 1.5 A . More current may be supplied up to the maximum current of 5 A, but the charging port may apply current limiting, or even shut down.
35.
If a 12volt power source is applied to either pin, the batteries are charged at 22mA . If both pins are used, the batteries are charged at 44mA . The 12volt feed is via two 330? current limiting resistors and the wired in fuse.
36.
You should properly connect up the LED with a current limiting resistor-but the amount of current required for a particular LED depends on the nature of how it was manufactured-and how much light it's going to put out-and to know that you need a data sheet.
37.
A similar theory was also proposed by Davydov in 1939 . Although it gives the correct direction of rectification, it has also been proven that the Mott theory and its Schottky-Davydov extension gives the wrong current limiting mechanism and wrong current-voltage formulae in silicon metal / semiconductor diode rectifiers.
38.
Safety precautions vary from designed in safety precautions such as current limiting devices as well as actions such as " how to work on a solar array without dying . " Solar for example has both parallel and series wired panels and the short circuit problem is not nearly as problematic as the open circuit problem on the DC side.
39.
As to what the surge protector is doing, my guess is current limiting, however this is not what the surge protector is really designed to do, it might be a byproduct of its function, so it's not a solution to your broken heater . talk ) 04 : 44, 13 December 2010 ( UTC)

If the battery voltage with no load is much higher than the proper operating voltage of the LED, you might need to connect a current limiting resistor in series with the LED . You can avoid this by making sure the number of pairs of metal elements in the battery is high enough to light the LED but not too high.
