UPSEE: Important Questions and Preparation Tips – Electronic Devices
About the exam:
Uttar Pradesh State Entrance Examination (UPSEE) is a state level engineering entrance examination for degree level engineering institutions and other professional colleges. It is regulated by Dr. A.P.J. Abdul Kalam Technical University (AKTU) formerly known as Uttar Pradesh Technical University (UPTU).
Important Concepts:
UPSEE: Important Questions and Preparation Tips – Dual Nature of Radiation & Matter
Some previous year solved questions are given below:
Question 1:
Solution 1:
Hence, the correct option is (a).
UPSEE: Important Questions and Preparation Tips – Alternating Current
Question 2:
A long silver tea spoon is placed in a cup filled with hot tea. After some time, the exposed end (the end which is not dipped in tea) of the spoon becomes hot even without a direct contact with the tea. This phenomenon can be explained mainly by:
(a) thermal expansion
(b) conduction
(c) reflection
(d) radiation
Solution 2:
As atoms in the spoon vibrates about their equilibrium positions and transfer energy from one end to other end. This process is conduction
Hence, the correct option is (b).
UPSEE: Important Questions and Preparation Tips – Electromagnetic Induction
Question 3:
Solution 3:
Hence, the correct option is (b).
UPSEE: Important Questions and Preparation Tips – Magnetism
Question 4:
A perfectly black body is one where
(a) absorptive power is infinity
(b) absorption point is 0
(c) emmissive power is 1
(d) absorptive power is 1
Solution 4:
A perfectly black body neither reflects nor transmit, (i.e. r = 0, t = 0) any part of the incident radiative energy but absorb whole of it or we can say its absorptive power is 1.
Hence, the correct option is (d).
