Question 2

A Si diode has a reverse saturation current of 10 nA at 25oC. If it operates at temperature of 75oC then the value of reverse saturation current is

Question 3

Two silicon diodes, with a forward voltage drop of 0.7 V, are used in the circuit shown in the figure. The range of input voltage for which the output voltage

Question 4

In the circuit show, both the diodes are ideal,

If then the output waveform of the circuit can be represented by (assume all the diode to be ideal)

Question 5

A voltage 1000 sin ωt Volts is applied across YZ. Assuming ideal diodes, the voltage measured across WX in Volts, is

Question 6

In the circuit shown below, the knee current of the ideal Zener diode is 10 mA. To maintain 5 V across RL, the minimum value of RL in Q and the maximum power rating of the Zener diode in mW, respectively, are
