Question 1
Consider the zener diode regulator as shown in figure below:
Where supply Voltage starts from +30V and goes on decreasing up to 0 volts. Let V1 volts is the supply voltage (maximum) at which zener diode regulator loses its regulating ability then V1 is___ volts.
Question 2
A 2.7 V, 50 mW Zener diode is used as regulator. Load current varies between 3 mA to 13 mA. Assuming minimum input voltage is 12.5 V, the maximum input voltage for safe operation is_____volt.
Question 3
Fig. shows the electric voltage regulator. The Zener diode may be assumed to require a minimum current of 50 mA for satisfactory operation. The value of R to require for satisfactory voltage regulation at the circuit
Question 4
In the Zener diode voltage regulator circuit shown in the figure below, the Zener diode has the following parameter
VZ =6V, RZ = 0Ω
