    I found no videos on the derivation of Impedance formula derivation so dear friend you can check physics by manjar sir video for reference ❤thanks, it's specifically for class 12th student of cbsc,

    So far, it is best video on resonance, all others just start bombarding you with formulas without explaining the underlying logic (which is so more important, because without logic you forget all)

    Resonance doesn't mean maximum output or maximum current. It is defined as the condition in ac circuit under steady state when current is in phase of voltage.

      There are two cases.

    I didn't understand one point. You said that Vmax is going to be constant if we change w. But if we change the frequency Vmax is going to change,isn't?(because of V=B.A.N.w sin(wt))

    • @jagruti_b
      @jagruti_b 2 года назад

      They didn't mean to say Vmax is going to be constant. They meant to say how do we get Imax while keeping Vmax constant, so the only thing we can change is w by changing the frequency.
