Re: SSK Rajasthan University
The previous year question paper of Basic Electronics subject of 2nd Sem of B.Tech Engg course offered by JRN Rajasthan Vidyapeeth University Rajasthan, Distance Education Center - SSK College is as follows: Answer any three questions (Question 1 is compulsory) Q.1 Briefly explain any one of the application of OP-AMP ? Q.2 Explain band theory of materials & classify the material accordingly. . Q.3 Explain voltage source and current source ? Q.4 Explain V to I & I to V Converter Q.5 Differentiate between active & passive components. Give three e.g. for each along with their symbols Group B (25 Marks) Answer any three questions (Questions 6 is compulsory) Q.6 Draw the CKT of OPAMP adder or Explain ? Q.7 Draw and explain the V-1 characteristics of PN junction ? Q.8 Explain Differential amplifier & make comments on CMRR. Q.9 Draw the i/p &o/p characteristics of CB connection what do you infer from these characteristics? Q.10. Draw the dl load line of transistor with neat diagram ? Group C (25 Marks) All Questions are Compulsory. Q.11 Fill in the blanks ( each question carry 2 marks) 1. The device which converts a. c. to d. c. is _____________________. 2. The input resistance in common collector mode is _________________. 3. The most fast operating diode is ___________________ diode. 4. The man building block of an opamp is ____________________. 5. Transistor is transfer of __________________. Q.11 Multiple choice question. (Each question carry 2 marks) 1. An ideal voltage source has a) Zero internal resistance b) Infinite internal resistance c) A load dependant voltage d) A load dependent current 2. The i/p stage of opamp is usually a) R.C. Coupled b) In CE configuration c) A Differential Amplifier d) A chopper Amplifier 3. Increasing the value of RE in a differential amplifier a) Increases the differential gain Ad b) Increases the common mode gain Ac c) Decreases CMRR d) Increases CMRR 4. A real current source has a) 0 internal resistance b) Infinite internal resistance c) A small internal resistance d) A large internal resistance 5. The most commonly used bias method is a) Base resistor method b) Biasing with feed back resistor c) Voltage divider method d) Fixed resistor method . Q.11 True or false (each question carry 1 marks). 1. A vacuum tube will only conduct if its anode is kept at positive potential w.r.t. cathode. 2. The power transferred is maximum when load resistance is equal to internal resistance of the source. 3. Solving of an electrical circuit will give the same result whether the source is treated as a voltage source or as a current source. 4. Op-amps can amplify both dc and ac signals 5. The Open – loop voltage gain of an op-amp is very high. |
