धन्यवाद सर,,,, काश की में आप से स्कूल या कॉलेज पड़ा होता,,,, तो कितना ज्ञान मिलता,,,,, खेर ठीक है,, इस माद्यम से मिले हो ये भी बहुत हे,, आप ऐसे ही प्रकट होते रहिये ज्ञानवर्धत वीडियो के साथ,,,,, धन्यवाद
Sir matlab ki dc source me potential difference jada hota hai tabhi to wo conventional cirrebt glow karata hai na aur ac me potential fluctuate hota hai is liye ye apna current ka direction change krta hai .Ab mai samjha .Hai na sir.
In DC current remains constant i.e rate of flow of electrons is constant. While in AC rate of flow of electrons varies with voltage, does this varying AC current doesn't damage electric devices ??
sir, how without any source A.C changes its direction and WHY D.C do not change its direction. WHY A.C strength decrease as you said in video and why it do not decreases in D.C?
Sir what do u mean by saying current became maximum?... And can u explain why such a thing dont happen in case of dc... Or does current always flow maximum in dc? Someone please answer my doubt please!! :)
Bro in DC the current rises from 0 to maximum (in very short time) and if we turn the switch off then the current will decrease at a very fast rate to zero In ac current when we say the maximum current it means that the current is at its most high value for a voltage and then it starts decreasing and then it changes its direction and become maximum(negative) and repeated
Hello Arnab Krittika Ghoshal Das ! You are welcome and thanks a lot for the support you have shown. Aap sab ke saath se hi ye channel hai. SHM is LIVE.
sir, please tell how how without any source A.C changes its direction and why D.C current do not change its direction.WHY A.C strength decreases while DOES D.C STRENGTH ALSO DECREASES?
Sir.... Namaste.🙏🙏 Sir jo hmare ghar par power supply hoti h transformers ke throw wo bhi ek ac power supply hota h to....potential zero hone par hamare ghar ka bhi light on off... On off hona chahiye na to kyu nhi hota aisha......?
Ac source me + - nai likh sakte Source aisa hona chahiye jo polarity badalta reh(for ac source) Phase difference: lets say if i leads v by 90° then i pehle jhapad jhupi kar raha hai as conpared to v.btwz this is the case of capacitor
Nice. How can we practically understand that current is in phase with voltage for pure resistive circuit or lags behind voltage in inductive or leads the voltage in capacitive circuit as our our practical domestic circuits are mostly of inductive nature? Precisely how can be physically get the concept of phase difference?
Resistance for a given material is always constant unless don't change the temp. And other physical quantities . So resistance cannot be variable. #ohm's law
