xray kv circuit, xray high voltage circuit
Переглядів 24 тис.3 роки тому
Electrons require DC KV voltage across x-ray tube for acceleration. x-ray high voltage circuit/ high tension circuit / x-ray kV circuit provides electrical power to x-ray tube. This video completely illustrates how autotransformer, step up transformer, bridge rectifier of an x-ray kV circuit works. Please like, comment, share, subscribe.

Great video. Well explained. Helpful. Thank you.
Best video 🥂
Where is flament transformer ?
My god ...best explanation ever❤
Best❤ thank you
Excellent, the confusion is always regarding the width of the effective focal spot.
Thank youuuu
Thank 🎉you
It is just great! The animation represents the theory in an easy-to-understand way, what a huge help!!
Nice
Great video. Does a significant part of the x-rays get absorbed in the x-ray tube due to not being scattered towards the window?
Excellent video please start making video again on further topics.
What an explanation sir... Thank u very much❤️❤️
Very good sir
Thanks 🙏🏻
amazing!
Your videos are the best
Nice
Ma'am you only say step up transformer high voltage circuit But you don't say step down transformer low voltage Please ma'am make a video of step down transformer And provide a diagram of step up and down transformer in one figure. By the way thank you ma'am ❤
Is simple bro step up has more coil turn in secondary winding, and it increases voltage(that's why called high voltage transformer) and decrease current and exact opposite is for step down transformer.
How many speed rotation
Excuse me, Could you explain me how to obtain tube current(Observed) parameter from the circuit in the video?
Tube current is measured by ammeter incorporated in kv circuit not in ma circuit. You may watch kv circuit .
Fantastic video.
Thank you.
Off focus radiation explains detail sir

When anode is + charged mater and cathode is -ve charged matter why only electrons from filament is accelerated not from - ve side ??
Electrons are free inside xray tube, after thermionic emission. Filament is in _ve side only
@@radiationphysicsradiationb5460 my question is simple , when positive and negative voltage from rectifier fed to anode & cathode wt will be happen ? Do the cathode is connected to ground ? I know there will be points like s , l, c other than these there wont be any points . Wt I understood is the negative voltage is connected to ground at anode side and positive voltage is fed to anode will help to attract electrons from filament , correct me if i am wrong
Well if u want the basics. Anode is positive mean, anode is lacking electrons. Cathode is negative means cathode is having surplus electron. If Free ellectrons are placed between two electrodes and one of the electrode is positive other negative or ground level then electrons will move towards positive electrode. If anode is at ground and cathode at negative(surplus electrons) then also electrons will flow towards anode. Electrons will naturally flow towards less negatively charged plate . Or in otherwards towards more positive plate.

To the robot narrator: 180*400 = 32 kv. That does not compute!
Thanks for pointing out the calculation error. Hope the rest of content is useful to u.
They did not error. Only partly, due to skipping an important feature. This Transformer has a center tap. Therefore, each secondary winding only has half of the voltage. Combined makes 72kv. But half is 36kv each side. There will be losses due to the core, so 32kv is a close estimate.
everybody should watch this!! This is a excellent explanation .....superbly done
Good

Nice knowledge

Sorry sir, I want to know, basic concept I know electric current move in closed circuit. Filament and anode are away from each other. How cathode become negative charge and anode become positive charge. If you can clarify it, Where can I find concepts.
KV circuit makes anode positive and cathode negative in an xray tube. Circuit is completed (closed ) when electrons flow in vacuum between cathode and anode. You may refer to last video ua-cam.com/video/xZgFK4G0n_0/v-deo.html
