1/2
Chemical Engineering (A1):
A fuel cell is a device that converts the chemical energy from a
fuel into electricity through a
chemical reaction of positively charged hydrogen ions with
oxygen or another oxidizing
agent. Explain the functioning of the fuel cell.
Civil Engineering (A2):
Radiations from cell phone towers are considered to be dangerous
for the body. Explain
from the viewpoint of electromagnetic waves.
Electrical and Electronics Engineering (A3):
How does an induction motor start?- This is the question that
startled most of us when we
noticed it in 3 idiots, but as an electrical engineer, an IM is
one of the most important things.
Explain the starting and functioning of a three phase induction
motor by taking the help of
the revolving magnetic field theory.
Mechanical Engineering (A4):
Youll definitely perform the Swinburnes test on a DC Shunt motor
in your second year
being in mechanical engineering discipline. To get a clear idea
beforehand, study and explain
the Swinburnes test of a DC Shunt motor and the speed control of
the same.
Computer Science Engineering (A7):
Gray code, also known as the reflected code, is a unit distance
code, unlike the binary
system. Explain the advantages and uses of the gray code and
also show the process of
conversion of binary to gray and gray to binary code.
Electronics and Instrumentation Engineering (A8):
It is not easy to operate an induction machine. There are
various processes involved in the
speed control and braking of the induction motor. Explain
briefly about various speed
control and braking methodologies for a three phase induction
motor.
Electronics and Communication Engineering (AA):
For switching applications, a transistor is biased to operate in
the saturation or cut-off
region. Explain the property of a BJT to operate as a
switch.
Manufacturing Engineering (AB):
Transformers are present everywhere and help us in all aspects.
Youll be performing the
Open Circuit and Short Circuit test on a transformer in your
second year. To ease out things
for future, explain the open circuit and short circuit
characteristics of a transformer.
MSc Economics (B1):
Explain how to perform integration and differentiation using
operational amplifiers.
MSc Chemistry (B2):
Electroplating is a process that uses electric current to reduce
dissolved metal cations so
that they form a coherent metal coating on an electrode.
Illustrate the process using yourcreativity and explain the process
of electroplating.
