  • Let's explore why the alternating current in a capacitor leads the voltage across it by a quarter of a cycle.

    I watched almost all your electromagnetism videos and my misconception that great content on CZcams must be highly viewed or should come from a famous channel has been broken.
    Unbelievable that such quality content is freely available for all that too in small 10-12 min videos.
    Your method of teaching so intuitively and logically is awesome!!

      I don't know that if Khan Academy wasn't famous 2 years ago but it is very well known now. I have a feeling that its website was still famous at that time.

  • @mohfa1806

    Thank you for your great educational lessons
    I have question please : i am confused how we can write : Vs= Vc knowing that the capacitor "gradualy" raise its voltage and doesnt respond instantaneously with the voltage source ! , why we are ignoring this fact and treating capacitor as if it is a resistor ?
    Thank you in advance

    • @netional5154
      @netional5154 Před 11 měsíci

      Yes, my question exactly. Apparently the current is so high that the voltage across the capacitor is almost exactly in sync with the voltage of the power source. In that case the phrase 'current leads the voltage because the capacitor must first be charged' is not correct. It should say something like 'current leads the voltage because it's related to the difference in voltage which is maximum before the voltage peaks'.

  • @sonorousgaming7202
    @sonorousgaming7202 Před 7 měsíci

    Well that is exactly the rate of change. We can now say that current I is proportional to the rate of change of voltage V wrt time 😊

  • @ahmedsami194
    @ahmedsami194 Před rokem +1

    One second... When the generator voltage is increasing from zero,how the current is maximum? There is no voltage in the circuit there should not be a current.... I studied in Dinamo that when the voltage increase the current increase as the same

      Ac generator. I think he talks more about this in his lessons on inductance where he explains how the ac geneotor works.

  • @Dhyaneshwar-um6ln
    @Dhyaneshwar-um6ln Před 5 měsíci

    But why more change in voltage means the current should reach the maximum value?
    Edit: I get it, since the voltage change is maximum therefore the current it induces should also change by maximum, any other change is lower than the maximum change and hence current doesn't reach a higher value.
