1.	What is the effect of the input on the transistor Q2?(a) bias on Q2 decreases(b) bias on Q2 is constant(c) bias on Q2 is zero(d) bias on Q2 increasesThis question was posed to me during an interview for a job.The question is from Basic Electronic Voltmeter topic in chapter Electronic Instruments of Electrical Measurements
Answer» The correct answer is (d) BIAS on Q2 increases The best EXPLANATION: The bias on the transistor Q2 increases when the input voltage is applied. As a result a proportional amount of CURRENT flows through the meter. HENCE the deflection of the meter is directly proportional to the applied voltage within the DYNAMIC range.
