    Hi! When you do the module of H(jw), wouldn't it be (1-LCw^2)^2 - R^2C^2w^2? Since we are doing j^2 = -1. Let me know if I am wrong.

    • @electricalengineeringmadei1041
      @electricalengineeringmadei1041 10 месяцев назад

      No because I am not doing "j^2" for calculating the magnitude of a complex number. I just need to take the imaginary component which is RCW in this case, square it and add it to the square of the real part (this is the definition of magnitude that I have explained in the different video). Hope this helped.

    I know that the solution of a differential equation depends on its form. Does this differential equation (L di(t)/dt + Ri(t)/tau = Acos(wt)) have the same solution as the general one (dy(t)/dt + y(t)/tau = Acos(wt)) if there is a constant multiplied by the differential term (L*di(t)/dt)? Or does this constant indicate that the differential equation is not of the same form as the general one? Must we divide by L and take tau to be L/R so the equation becomes di(t)/dt + (R/L)i(t) = (A/L)cos(wt) so that the differential equation matches the general form? Or does this not work because now the amplitude becomes A/L instead of A, the given amplitude?

    • @electricalengineeringmadei1041
      @electricalengineeringmadei1041 Год назад

      Sage, in order to use the general solution your equation should match the general equation and therefore, you have to device by L first. Does that make sense?

    Hi sir, thanks for your helping us to get better marks. I have a question about the equations in time between 22:30-23:00. We said that i2=i3 and also i3=i4. From the first equation we get V2=-V3 but from the second one, we get 5V3=3V2. Is there something that i might have missed? Best regards.

      we said that i2=i3, at the same time 3is=i2. Am I wrong? From this point V2=i2 so we can say that V2=V2-V3/2 and this equation shows V2=-V3. thanks for responding.

    Just a side note: Classes in school are always exclusively a subject. Just math or just physics. What students need is something that is like a Math/physics class, because after we study just math for a semester, then the next semester just physics, we can't remember all of the math that goes along with the physics so we never see the important connections, of using our math skills to solve real problems. If it was mixed we would learn both of them, because we used all of our skills. I assume you are a professor, so if you agree with me maybe you can pass it down the line. I'm not sure if it is your intention, but watching these videos is what I've needed in an algebra class my whole time in college. Algebra class never took it this far or made it this real and applicable. With these videos I feel like I'm getting two things done at once. I see you simplify things, and sometimes you skip a lot of algebraic steps, but it's what I needed to make those skills solid. When I get stuck on your steps I stop the video and figure it out. Plus I'm learning circuits. Sorry for the long message, but I hope one day schools start to mix classes. I don't know if that's your intention but it's perfectly what I needed. Thanks.

    For I(2) I was a little confused. You got conductance for I(2) over conductance for I(3) and I (4)? But the conductance for I(2) is the resistance of I(3) and I(4)? Then total conductance was the added resistance? Does that mean when resisters are parallel that the conductance of the first one is the resistance of the other? If not, I don’t know why you used all resistance values as conductance. Thanks
