  • Question 9
    1 / -0

    For the given circuit shown in figure, the potential of the battery is varied from $$10V$$ to $$16V$$. If by zener diode breakdown voltage is $$6V$$, find maximum current through zener diode.

  • Question 10
    1 / -0

    The figure represents a voltage regulator circuit using a Zener diode. The breakdown voltage of the Zener diode is 6V and the load resistance is $$R_L = 4 k \Omega$$. The series resistance of the circuit is $$R_i = 1 k \Omega$$. If the battery voltage $$V_B$$ varies from $$8V$$ to $$16V$$, what are the minimum and maximum values of the current through Zener diode ?
