    A shunt regular is shown in the figure has a regulated output voltage ...

    Maximum input current

    The Base current is equal to current flowing through Zener diode
    Vz = IB
    → Ic = βIB = βIZ
    I1 = βIZ + Iz
    1A = (49 + 1) Iz
    Iz = 20 mA
    ∴ Power dissipated by the Zener diode Pz = VzIz
    = 9.3 × 0.02 = 186 mW
    Power dissipated by the Zener diode Pc = Ic × Vc
    IC = 99Iz; VC = VO
    ⇒ PC = 0.98 × 10 = 9.8 W
    ∴ The ratio =
