Question 1

In the voltage controller circuit shown in the figure (assume that op-amp is ideal). The BJT has VBE=0.7V & is very large and VZ =4.7V. For a regulated output of 9.4 V, the value of R (in kΩ) is _____

Question 2

In the voltage regulator circuit in figure the maximum load current IL that can be drawn is

Question 3

For the diode circuit shown below VZ=6V, and Vγ of the diodes to be 0.7 V. The required value of Vi to get Zener diode in the breakdown region.

Question 4

A linear voltage controller is construct using discrete components as shown in figure. Then the output voltage V0 is (in Volts)

Question 5

A DC power supply, when connected to a load exhibits 20 V potential across its terminals while delivering a current of 2 A to the load. When the potential across the terminals are measured while the power supply is kept idle, it shows a potential of 35 V. Load regulation and value of connected load to the power supply are, respectively

Question 6

The output voltage of the regulated power supply shown in figure is
