Electrician interview questions answer in Hindi (part 1)

 Electrician interview questions answer 

1) Isolator and circuit breaker me difference  - 

*) isolator or circuit breaker ye dono hi electrical device ko switch On - OFF karte ke liye use me lete hai. But isolator hmhe kisi bhi fault se protection nhi provide krata hai ,jabki circuit breaker fault hone per apne aap circuit OFF ker deta hai. 



*) Isolator ko hmm no load per open karte hai and circuit breaker full load per open hota hai. 



2) phase voltage and line voltage me difference  - 

*) phase voltage  -  Jb hmm kisi ek phase or neutral /earth ke bichh voltage ko measure karte hai, tb ye phase voltage kahlata hai, isse ( Vph) se denote karte hai. 


*) line voltage  - jb hmm kisi bhi two phase or line ke bichh me voltage ko measure karte hai tb wo line voltage kahlata hai, isse hmm ( VL) se denote 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
