    Thank you sir, you brought a light on the darkness while i was scrambling to do my physics lab.

    Inductive reactance:
    LIMITS high frequency, ALLOWS low frequency
    capacitive rreaactance:
    LIMITS low frequency, ALLOWS high frequency

    This is so amazingly explained, remains imprint in my mind. Can you help me model a biological cell as a circuit.

    Here i= 1/wL for inductor and i=wC for capacitance, but my teacher did it the other way around,i.e i=wL and i=1/wC is that the same thing? since i get same result or?

    • @rudratiwari1758
      @rudratiwari1758 Год назад

      no I =omega x L and I = (omega x C)^-1.....I=wL and I=1/wC

    sir can I know how the energy is lost due to a inductive or capacitive reactance , meanwhile in a resistor they are dissipated as heat

    • @PrabhjotSingh_24
      @PrabhjotSingh_24 3 года назад

      They are also made of some material which has it's own resistance....they lose energy in the form of heat but way less than a resistor ideal...I think!

      Energy needn’t necessarily be ‘lost’. Capacitors and inductors store energy as electrical potential energy and magnetic energy respectively. No dissipation.

    • @lightspeed2014
      @lightspeed2014 3 года назад +1

      Actually it's not lost, energy is consumed by both the inductor and capacitor and stored as magnetic and electric fields respectively in one quarter cycle, in the next quarter cycle this same energy is released by both devices

    Sir the peak value of current is more than the peak value of voltage....is that the same always?
    Can current peak be less than voltage peak?
