Jzak Allah sir jee... Ap bht mehnat krty hein hmary liye... Sb s bri bat ap mein attitude nhi h sir jee.. Ap sb ko rep krty hein.. Ye achi bat h.. Allah khush rkhein.... Apki aaankhein b salamat rhen
You studied two type of transformers Step up ; increase the output of AC voltage Step down ; decrease the output of AC voltage It written in this regard jazakillah and I hope you understand ❤ inshallah
Mutual induction waly topic ma to ap ny coil ko batery sy connect kia tha jo dc source hy... wahan phir kaisy current induce hua secondary coil ma??????? dc ki waja sy change in flux to hua nhi
Transformer dc current ke sath current induce kerta ha likin uus ka koi faida nahi daily use mein, transformer sirf current kum ya ziada voltage kerne ka kam ac current mein kerta ha.
Its my First comment on U'tube...really mind blowing sir...I Really appreciate ur work...I can surely say ur all lectures are perfect ..stay blessed and thnkxfor helping us
u r the best teacher even for the teacher i always take help from your lectures for preparing my online classes. Allah ap ko emam r health ke best cndition ma rkhay.r ap asay he helpful rhn
Sir no words for you ...........Thanks alot If you don"t mind can you tell how many subscribers do you have......... May ALLAH bless you alot more.....
Sir primary voltage (P) ko AC current dete hai to secondary voltage (S) bhi AC current ka deta hai to pher DC current ka Q nhi deta QK sir mutual induction mein to sirf current produce hota hai
Ac current changing magnetic field produce krta hy jis sy secondary coil me current induce hota hy Dc current changing magnetic field produce nhi kr sakta is lye secondary coil me current induce nhi ho ga.
Q k secondary coil me current tab induce hota hy agr primery coil me current change ho, wrna nhi hota. Dc current change nhi hota same rehta hy is lye is lye ye secondary coil me current induce nhi kra pata.
Because DC. Is flow in one direction ... Its value always constant no change electric flied and no produce magnetic field .agr DC produce ho ga lenz lawphr wrong hai .... Magnetic flux change then produce induce EMF and EMF produces current .. according lenz law produce current in always oppose cause that produce it... It mean current always directed clock wise and anticlockwise ...it is ac current ac. Not DC...
sir my question is when the AC voltage is continuously increasing and decreasing then how can we get a definite value of V in the primary coil ( agar voltage kam ya zyada hota ha to ham voltage kitni kahein? agar aap 3rd para parhy tou udhar likha hua ha Voltage Vs is proportional to Voltage Vp jabke voltage alternating ha)
sir aap nay kaha kay agar hum nay higher voltage ko lower voltage may convert karna hay to hum transformers ka use kartay hain. Sir agar hum nay apnay phone ko charge karna hay to hum higher volts ko low karain gay, is case may transformer hamaray phone may ho ga ya charger may ??? please answer ...........
Right hand rule ke according kere gay! Jab grip mein curling fingers direction of current ki taraf ho tou thumb north pole ki taraf ho ga. Tou North se magnetic field south ki taraf flow kere gi.
Sir question is Agr primary ko voltage dia jaay to secondary m b pass kar jaay ga ircon core hy to current to forn chala jaay ga . Ya mutaul py kaisey base howa yahn source h iron ka wahn ni tha
No no no... Primary coil ko directly iron core k uper nhin vound kia balky pehly iron py insulated material ki coating hoe phir uper primary coil ko vound kia, Primary coil sy sirf magnetic field iron core me jay gi but no current..
Thk h i suppose koi b insulated material h question is k ya mutaul to na howa q k wahan to koi aik platform ni tha wahn phr b current dosri jagh gya .yahn to iron core h jo direct current pass krwa dy gi secondary m .tranformer phr mutaul k base py ni kam kar raha😕
Iron cor k ilawa b magnatic field primary sy secondary coil me ja sakta hy lakin iron core magnetiz ho k bohat achy sy fied pass kra deti hy. Ham iron core to sirf is lye use krty hn ta k field achy sy primary to secondary travel kry...
Excuse me sir! Sir how primary voltage is directly proportional to number of turns in primary coil. sir my question is how primary voltage depend upon number of turns in primary coil. Sir bit explain!
Sir ohm's law to kahta hai k i dirctly proportionl hai v k ya v dirctly porportional hai i k lykin yahn voltage increase ho to current decrease hota hai..
Yes dear ! Wo is lye k temperature jab increase ho jata hy to phir current ko increase nhi hony deta linearly. Temperature should be constent for applying ohms law, 2ndly it is only applicable to metalic conductors.
