  • 23. 1/Rp = 1/24 + 1/24 + 1/12 = 4/24

    Rp = 24/4 = 6 ohm

    Total = 6 ohm + 12 ohm + 12 ohm = 30 ohm (d)

    25. Step down = Vp/Vs = Np/Ns = Is/Ip

    Vp/Vs = Np/Ns

    220/Vs = 1200/ 300
    1200Vs = 300 x 220
    Vs = 66000/1200 = 55 Volt


    Ip = V/P = 220V/110W = 2 A

    Is/Ip = Np/Ns
    Is/2A = 1200/300
    Is=
