    Sir mai aapko khbai v solutions ke liye follow nahi karta..balki aapke concepts ke liye karta hu.. issliye agar waqt thoda adhik v lage toh v koi baat nahi sir..bas hamara concept clear hona chahiye taki hum exam mai jaldi bana paay.. Thanks sir😍🙏👌

    i was not very sure of solving the problem at first but with that one sentence just try it for once totally changed my mind .... at first i was following differnt academy for concepts from there i got some basic idea but the way you handle every circuit is just fantabuluous.

    sir, have a question. Suppose in a network, there are three sources- one current & two voltages and current in a branch is required. In case of superposition, instead of calculating for 3 sources differenty, can we take two voltage sources together & then the current source differently & calculate currents for them in two steps?

    Sir, a second approach for Q5: gate 2014 Electrical Engineering. At 17:40
    I want to know if this is correct way...
    Rs = (k^2) * Rp
    k = N2/N1 = 2/1 = 2
    Rp = 1 ohm (given)
    So, Rs = (2^2) * 1 = 4 ohm
    And this is a step up transformer so, voltage will increase by factor of 'k' so k*Vin = 2sin(wt).

  • @gurudattsharma4560

    Sir last question me Maine bina two-port network k Nikal Gaya tha:
    N2/N1=V2/V1, isse V2=2sinwt
    Now we when we refer the primary Impedance of transformer with respect to secondary winding, we multiply the primary Impedance by square of transformer ratio.
    1x2²= 4 ohms. Please reply if approach is right or not?

    @aritraray4005 7 ปีที่แล้ว

    Sir, we can solve the second question much easily if we refer the quantities to the secondary side. Also, how can transformer action be valid if we are applying dc voltage in secondary to evaluate Zth?

  • @anandkumar7964
    @anandkumar7964 6 ปีที่แล้ว

    At 22:00 transformers question explanation is little wrong as we can’t say that because secondary current is zero so primary current will be zero as there will be no load current which do not depend on load or secondary cutrrent.

  • @kamalasiwal5516
    @kamalasiwal5516 6 ปีที่แล้ว

    In the last question if we refer primary side on secondary we will be able to solve this problem in few seconds..

  • @vishakhasinha2321
    @vishakhasinha2321 6 ปีที่แล้ว

    Sir, if we calculate Rth here by using formula Rth = V(open circuit)/I (short circuit) , then I am not getting the same result.

    @rajusk-cd5fp 6 ปีที่แล้ว

    SIR WHY THE CURRENT WHICH PASSES THROUGH THE 2 K-OHM RESISTOR IS TREATED AS POSITIVE?
    FROM THE CIRCUIT IT IS EVIDENT THAT THE CURRENT THROUGH THE 2 KOHM RESISTOR IS AWAY FROM THE NODE SO THAT CURRENT WILL TREATED AS NAGATIVE..

    • @anirbanshyam8836
      @anirbanshyam8836 6 ปีที่แล้ว

      in 1st part the circuit was open circuited so no current will flow, bt in 2nd part the circuit is closed so current will flow , assumed that the current will be I(dc)
