What amperage can a fly back of a 20 to 22 inch screen have?

GOOD LATE THROUGHOUT MY QUESTION IS RELATED TO THE AMPERAGE OF A FLY BACK, I KNOW THAT I CAN HANDLE VOLTAGES FROM 20 THOUSAND TO 30 THOUSAND VOLTS AND FREQUENCIES OF 15 THOUSAND HERTZ, BUT AMPERAGE CAN COME TO HANDLE BEING OFF AND BEING UNDERTAKEN A LOT OF THIS BECAUSE I HAVE HEARD THAT HE IS DANGEROUS EVEN IF I DON'T KILL YOU A COURSE COURSE I PAY THE SAME DAY HE TOLD US THAT HE DID NOT FEEL ANYTHING BUT THE OTHER DAY HE FEELS HUSBAND AND WITH TACHYARDS, BUT HE IS ALREADY STABLE

All flayback coils handle different currents, maybe you mean specifically the high voltage current, personally I have never measured that current because I have no instrument to measure it, but the books say it is a very small current that does not reach at 100 milliamps, which does not make it a dangerous current, high voltage can burn the skin and the discharge feels quite strong, it does not kill but if the environment can be dangerous, since when resibuting a discharge by reflex one tries to leaving or moving away from the source of the discharge, being able to throw objects or hit with objects, that would be more dangerous than the discharge itself, your friend's tachycardias are more because of the nerve or experience lived, we could say a more psychological effect, that doctor, that's why these tensions always have to be respected and take all precautions or safety measures, the flayback even if it is off, connected to the kinescope if for any reason it is necessary It is always necessary to disconnect the screen from disconnecting the suction cup from the screen, it behaves as if it were a capacitor saving the charge for up to several days ... greetings.

The high tension of the flyback although it usually reaches up to 25 kv or more in some tvs. the intensity or current of it is in the order of the maximum 14 milliamps, since most use awg 40 wire in the winding from eat.es this is done so that the voltage is very high but not the current, too low so that it is not lethal. I hope to have answered your question. greetings

Thank you for that, it was that I did not file it for being so low

It was designed like this from the beginning because the kinescope needs high voltage but little current to give image, that makes it very deadly in case of receiving a discharge. In this case it could have been the tube or kinescope that was loaded with the high voltage and discharged by his friend giving him an electric shock.

victor that off or on the same handles the 14 milliamps

The flyback is not in the current. The high voltage loads the tube and in some cases it is loaded with this high voltage and if one touches it it is discharged. If the TV is turned off the flyback does not work.

that is to say victor those 14 milliamps that you say sends them is on, that is, the feeling was the voltajaso of those things, here they already bought gloves of up to 20 thousand volts in the course in case something happens with that thing, victor with your experience that is download if you mess with the board or it is not necessary

Only very rarely is the tube or screen charged. Before touching, it can be discharged with an insulated cable, one end to ground and the other to a well insulated screwdriver and the tip of this touch inside the pacifier and the tube is Download and lose all danger.
