Q5.Consider the oscillator circuit shown in the figure. The function of the network (shown in
dotted lines) consisting of the
100kΩ resistor in series with the two diodes connected back-toback
is to:
Answer : Option AExplaination / Solution:
When the output voltage is positive the diode D1 is turned on making 100kΩ resistor to become parallel to 22.1kΩ. So the gain is reduced. When the output voltage becomes negative the diode D2 is turned on thereby again 100kΩ resistor to become parallel to 22.1kΩ. So the gain is reduced. With the use of diodes, the non ideal OP-Amp is made stable to produce steady

Q8.Michael lives 10 km away from where I live. Ahmed lives 5 km away and Susan lives 7 km away from where I live. Arun is farther away than Ahmed but closer than Susan from where I live. From the information provided here, what is one possible distance (in km) at which I live from Arun‟s place?
Answer : Option CExplaination / Solution:
Given Arun is farther away than Ahamed and closer than Susan from where I live is greater
than 5 km but less than 7 km clearly 6.02.
Q9.A person moving through a tuberculosis prone zone has a 50% probability of becoming infected.
However, only 30% of infected people develop the disease. What percentage of people moving through a tuberculosis prone zone remains infected but does not show symptoms of disease?
Answer : Option CExplaination / Solution:
P(a person infected but does not show symptoms) = 0.50 × 0.70 = 0.35
