    Considering the given circuit for first half cycle in order to determine the peak value of the current through the load resistor.
    From above figure

    I =
    V
    Req

    Where, Req = 2 || (2 + 2) =
    4
    kΩ.
    3

    Now, I =
    (10 – 0.7) V
    =
    9.3 x 3
    mA
    4 / 3 kΩ4

    = 6.975mA
    and IL(peak) = I ×
    2
    = 6.975 x
    2
    = 2.325 mA.

    Upto Irms or I(peak) follow the solution of above question. We know average value of a full wave rectifies is

    Iav =
    Irms
    =
    Ipeak
    =
    2.325 mA
    = 1.67 mA
