Why used 50Hz frequency in India ( Hindi)

 Why used 50Hz frequency in India - jo first electricity generate or invention hua tha wo "direct current (DC) "thi ,jo USA me hua tha, jiska invention "Thomas Alva edition "ne kia tha, jo ki 110Volt per operate hoti thi, but DC ke kuchh disadvantage bhi the ,jiske Karan "Nikola Tesla " ne "Alternative current (AC)  "ka invention kia, first invention jo 240V,3phase,60Hz tha.

 60Hz frequency - arc lamp jo 1 sec me 60 bar on off hote hai ,fir Nikola Tesla ne practical kiya or dekha ki, 60Hz frequency jo 1sec me 60 bar on off hoti hai, wo bahut fast hai jisko hamari Akhhe nhi dekh sakti hai or hmhe pta bhi nhi chalega ki lamp on off ho rha hai, wo sirf hame ON hi dikhega, us time unhone 60Hz hi prefer kiya .

AC current ki invention ke bad Thomas Alva edition or Nikola Tesla ki bicch me ek War hua tha, jisko "AC vs  DC" War kahte hai. 



Is war ke winner "Nikola Tesla " hue quki AC sabko sahi lga, tb us time USA government ne sabko AC supply dene ka wada kia, First supply jo ki USA ke gharro me gai thi wo single phase, 240volt,60Hz Thi. 

Ab apne Main topic per ate hai why used 50Hz frequency in India, india me 50Hz frequency kaise aye, jb world war hua tha tb us time koi government ek dusre se maddad lena nhi chahti thi, isliye British government ne khud ki electricity develop ki jo 220volt,50Hz thi, jaisa ki aap jante hai ki British ne bahut times tk hamhare India per hukumat ki hai tb us time india me 220volt,50Hz ki supply thi, uske according jo bhi equipment the wo 220volt,50Hz frequency per create hote the,or work karte the, jiske karan wahi frequency abhi tk chal rhi hai, ager hm frequency ko change karenge tb hamhare equipment sahi se work nhi karenge or kharab ho jayege, Isliye hm aj bhi 50Hz frequency ka use karte hai.

1 Ampere me kitne watt hote hai AC & DC me

Image
Q)  1 Ampere me kitna watt hota hai.  1 Ampere - one coulomb per second is called one Ampere.  1A = 1C/second  Hamare ghar me AC supply hoti hai or isliye pahle hmm AC motor ka watt nikalege.  Let . Koi ek Single phase motor hai ,joki AC supply per work karta hai, motor ki rating --- Voltage = 220v Current  = 1A Power factor = cos φ Cos φ = 0.8 Power (P) = V*I*Cos φ P = 220*1*0.8 P = 176watt Let. Koi DC motor hai uski rating --  Voltage = 220 Current = 1Ampere Power (P)  = V*I P = 220*1 P = 220watt Ager hmme voltage & power factor pta ho to hmm 1ampere ko watt me convert ker sakte hai.

Why cuts on the electric plug (Hindi)

Image
Cuts on the electric plug Ye cut sabhi plug me dekhne ko nhi milta hai ,ye sirf 'Brass' material ke pin wale plug me hota hai, brass matlab 'peetal' ke pin wale plug me hota hai,  Jabki aap ko aluminium ke pin wale plug me koe bhi cut dekhne ko nhi milega . Kuch plug me aluminium ke color wale  pin lga hota hai jisme bhi cut hota hai, ye pin bhi brass material ka bna hota hai, brass material per jang (Rush)  lagne ki chances hoti hai isliye isper 'Nickel' (Ni) chemical ki coating ki jati hai jo pin me jang (Rush) lagne se bachta hai  or pin ki strength  ko bhi improve kerta hai , isliye ye hmme aluminium ke jaisa lagta hai. Why cut on the plugs - plug ke pin brass material ka hota hai or brass ki conductivity bhi sahi hoti hai, but iska ek nuksan bhi hai ki ye material jyada heat hone ke wajah se ye pin failne (spreading)  hone lgta hai . Jb hmm plug ko kisi socket me lgate hai or usme jyada current flow hota hai, tb jyada current flow hone ki wajah se heat...

What is hot start and cold start in motor (Hindi)

Image
Q)   What is hot start and cold start in.           motor  ? Hot start - jb hmm motor ko bahur jyada time tk chalate hai toh motor heat ho jata hai or ager is condition me hmm motor ko OFF karke ON kare tb wo motor hot start hota hai, ya motor jyada heat hone per trip ho jaye tb hmm motor ko fir se ON ker de toh is condition ko hot start kahte hai.  Cold start   - jb motor bahut time se ON na hua ho toh motor ka temperature room temperature ke equal hoga or ager hmm is condition me motor ko ON karte hai toh wo motor cold start hota hai.  Motor ko jyada time tk ON rakhne per motor me jo continuously current flow hota hai uski wajah se hi heat produce . hota hai
