As given in the figure below, power rating and the zener voltage of the two zener diodes (Z1 & Z2) used in circuit are 1 W & 10 V and 0.6 W & 6 V respectively. Minimum zener current needed for the satisfactory operation of both zener diodes is 2 mA.
1. If the battery has no internal resistance, find the range of RL values in which the circuit can be used as a voltage regulator satisfactory.
2. What would happen to the operation of the zener diodes if the battery emf is changed to 10 V?
THANK YOU
