Cathode rays must be connected to negative terminal of battery while anode rays be connected to positive terminal of battery ... Pls correct the diagram given in this video

[maheshhublikar]

Mam in the ends of the discharge tube, there is (--) sign & there is written anode and in (+) sign there is written cathode
But mam in previous video(discovery of electron) it is (--) cathode & (+)Anode

[amitasrivatava]

Pressure is not too high it's too low

[KittySaysMeowMeow]

Ma'am but in ncert it is given that the proton was discovered in 1886 and the electron was discovered in 1900. How can the proton be discovered before the electron?

[hark.ion_]

You are explaining good but mam there is a problem pressure is not High and moderate, but pressure is low and the voltage of the current was 12000 w

[mohdashham]

Mam proton ke mass se kya matlab uski to size dekhi jae gi na mass zyadah hoga tab to wo cross kar hi jaega bin cathode me whole kiye
Agar proton size me electron se bada hoga tab na wo nahi ja paega??
Lekin size to dono ki same hai

[RakeshYadav-vkrj]

In previous video you have mentioned plate which is connect with positive terminal is called anode and plate which is connect to negative terminal is called cathode but in this video you have change the terminals please mention

[amitkumara]

Mam figure me
Cathode me positive terminal connect kar diye hai or
Anode me negative terminal connect kar diye hai ( ye figure right hai yaa worng)

[anjanarani]

Finally understood...am in 11th but nobody was able to explain it this good 👍🏻

[tulsijoshi]

Mam aapne piche lesson mein bhi cathode ray experiment btaya tha 41 min ki video mein and abhi bhi aapne starting mein time leliya vhi vapis se btane ke liye

[manikanain]

Hi mam,
Why does electron penitrate the anode and cathode doesn't??

[TheGamerUltra]

Mam your explanation is very good thank you so much 😊

[saisoumyabarik]

Mam they have given low pressure with high voltage not high pressure mam kyun ki mam agar low pressure nahi hoga toh particles k andar collision kaise hoga..

[farheenzaheer]

Metal ki plates men bhi tou atom hai is main sy bhi bhi electrons arrahein hon gy??

[fouzanmohammedshoukath]

mam in a atom we can say that the mass of electron is negligible. but in grams of water or any matirial how can we ignore the mass of electrons.

[anweshabasak]

Mam the perforated cathod is negatively charged but in the diagram it's positive so ....light mistake in diagram

[priyankakeshri]

Mam perforated cathode plate liya gya, kya scientist ko already pta tha ki positive charge particles bhi hoga atom me? 🤔

[shakirreza]

Mam in book it is written that pressure in discharge tube is very low

[gauravkhatri]

Canal rays when strick on ZnS then which colour glows ?

[priyanshigupta]

Mam last video me aapne btaya ki cathode is connected with negative terminal and anode is connected with positive terminal but here u opposite it... Please clear the doubt🙏🙏
