Sir, I have seen a question "If we increase the driving frequency in a circuit with a purely resistive load, do (a) amplitude VR and (b) amplitude IR increase, decrease, or remain the same?". The answer for both is -- they remain the same. But I am confused. Doesn't peak amplitude depend on the driving frequency - E0 = BAw - Then as w is increased, E0 should also increase? Thanks in advance
Sir induced emf current ko oppose krta h islya phase difference ata h lkn sir resister ma bhi to opposition hit h na current ky agance fr phase diferent q nhi ata h
Thanks for your quick response, sir. But in the EMI chapter, when we rotate a ring in a magnetic field and compute emf, there is no capacitance or inductance, only resistance. But the emf = Baw sin(wt), so E0 = Baw and E0 is then dependent on w. The faster we rotate, the more the rate of change in flux, and the higher the induced emf and current. So in the equation E = E0 * sinwt, how is this E0 different from the one in the EMI chapter. I think that is what is confusing me. Thanks.
sir if in inductor equal and opposite emf is produced then why not the net emf and hence current is zero if capacitor allows ac current then i am unable to visualize the mechanism please help thank you reply soon
Sir, in case of an inductor AC circuit, when t=t/4, emf is zero, but current is maximum. How does current flow in circuit when emf is zero? Please guide..
+Pradeep Kshetrapal DELAY. That's it clears everything now. Thank you very much sir. And Ashitosh thanku for asking that question because i was confused too.
Hannah the best way your life and the first half years in the morning to him,hug hjthjhghyudmsjem to be the first half of the year of high quality of life and the other hand is the only thing that would have to go back and the other side of the first half of this month and I don't think I can be a little too late
The formula is also in your lesson "XII-5.5 Generator A.C. (2014) Pradeep Kshetrapal Physics" at time 43:40. Thanks
sir how to know direction of current in a.C circuit???
There are no unique direction in ac so , it is impossible to find the direction of ac i have ever seen in class 12 ..
Sir i don't have maths in 11th & 12th... so, i found difficulty in understanding some derivations and numericals.. What should I do?
u should slap urself...life without maths is like a year without rain
you need a basic math
because physics is more related to maths

***** Thank you very much. It is clear now. Your service in answering doubts is as excellent as your videos.
Sir do these voltage stablizers of refrigirators and air conditioners work on the priciple like that of transformer???

Phasor diagram of capacitor circuit is wrong
