When Vi > 5, Vo = 5V

Test: Diode Circuits - Question 2

For the given circuits and input waveform determine the output waveform

Detailed Solution for Test: Diode Circuits - Question 2

Diode is off when Vi + 2 > 0.

Test: Diode Circuits - Question 3

For the given circuits and input waveform determine the output waveform

Detailed Solution for Test: Diode Circuits - Question 3

For V1 < 4 the diode is on otherwise its off.

Test: Diode Circuits - Question 4

For the given circuits and input waveform determine the output waveform

Detailed Solution for Test: Diode Circuits - Question 4

During +ve half cycle when Vi < 8 both the diodes are off. For V1 > 8, D1 is on. Similarly for the negative half cycle.

Test: Diode Circuits - Question 5

The maximum load current that can be drawn is

Detailed Solution for Test: Diode Circuits - Question 5

At regulated poer supply, Is = 30-9/15k or 1.4 mA. The load current will remain less than this current.

Test: Diode Circuits - Question 6

For the circuit shown diode cutting voltage is Vin = 0. The ripple voltage is to be no more than vrip = 4 V. The minimum load resistance, that can be connected to the output is (in kilo ohm)​

Detailed Solution for Test: Diode Circuits - Question 6

Test: Diode Circuits - Question 7

The circuit inside the box in fig. P3.1.31. contains only resistor and diodes. The terminal voltage vo isconnected to some point in the circuit inside the box. The largest and smallest possible value of vo most nearly to is respectively​

Detailed Solution for Test: Diode Circuits - Question 7

The output voltage cannot exceed the positive power supply voltage and cannot be lower than the negative power supply voltage.

Test: Diode Circuits - Question 8

The Q-point of the zener diode in the circuit shown below is​

Detailed Solution for Test: Diode Circuits - Question 8

Test: Diode Circuits - Question 9

A 2-port network is driven by a source Vs = 100 V in series with 5 ohm, and terminated in a 25 ohm resistor. The impedance parameters are

The Thevenin equivalent circuit presented to the 25 ohm resistor is

Detailed Solution for Test: Diode Circuits - Question 9

100 = 25I1 + 2I2, V2 = 40I1 + 10I2
Also V2 = 160I1 + 6.8I2
using above equations we get, Vth = 160 V and Rth = 6.8 ohm.

Test: Diode Circuits - Question 10

Find V1 and V2.​

Detailed Solution for Test: Diode Circuits - Question 10

800 = 10V1 – V2 and 3V2 = 5V1 = 0.
