Voltage Regulator - 2 Starter Quiz 4

A 24 V, 600 mW Zener diode can be used for providing a 24 V stabilized supply to a variable load. Assume that for proper zener action, a minimum of 10 mA, must flow through the zener. If the input voltage is 32 V. What would be the value of R and maximum load current?

A zener diode is used in the circuit as shown below which has zener dynamic resistance of 15 ohms. The zener knee voltage is 5 V. If the input voltage has a range from 10 V to 20 V then find the output voltage range if R = 200 Ω

For the Zener diode network shown below, determine Power dissipated by Zener P_Z

In the voltage regulator circuit, find power dissipation in Zener diode.
(VZ = 6V and Vi =12 V).

Consider the voltage series regulator circuit as shown in figure below. Assume that transistors are in active region with V_BE = 0.7V & β = 50. If the Zener diode is working in breakdown region with then the output voltage is

To maintain the Zener diode in ON state, the maximum values of input voltage V_i is _____ V.

(R = 200 ohm, R_L = 10 kohm, V_Z = 20 V and (I_Z)_max = 50 mA]
