Alternating Current - Voltage and Current Relation | video in HINDI | EduPoint

In this Physics video tutorial for class 12 in Hindi we explained the basic theory of alternating current and the the relation between voltage and current in AC. We also compared alternating current (AC) with direct current (DC). In DC the source may change its voltage, but does not change its polarity; whereas in AC the source chages its polarity in regular basis. This video lecture of Physics is indispensable for Science students of class 12 of any board, CBSE, ICSE or any other state board. In this lecture we see that a standard alternating current is that whose voltage and current are sine wave function of time. We also learn in this video tutorial that the wave for voltage and that for current have no phase difference.

Sir plz growth or decay of current in three circuits. Plz sir

[@sk-sm5zg]

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 ??

[@binitakumari2080]

Amazing teaching sir😊😊

[@Physicslover1729]

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.

[@shreyadeshmukh7197]

Sir why V=Vm sin(wt)

[@deepakahuja9461]

It a sin function

[@shouvikmondal1977]

Sir, why do we plot current in x- axis and voltage in y-axis???

[@karthikeyanp7037]

Both voltage and current lie in the same axis. But the magnitude of current is less than that of voltage due to resistance.

[@Shrejaiswal000o]

Sir aapki AC chapter class 12th pe hai kya

[@TheAITools47]

why current changes its direction ? current flows from negative to possitive as it is flow of electrons ? why to use conventional current?

[@shivsidar4639]

[@malathiov549]

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!! :)

[@lallanchauhan7694]

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

[@shivamkhare205]

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?

[@jeetpranav2304]

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
