Ques:- void main() { int x=4,y,z: y=–x; z=x–; } what is the output
Asked In :-
Comments
Admin May 17, 2020

Y=3 initially Y=0 then Y = --x Decremented then assigning value so Y=3
Z=3 z = x-- assigning x value to z first then Decremented so Z=3

Admin May 17, 2020

no output because no printf()
if we print y and z
the output is :
y=3
z=3

Ques:- in vfd why we did not give directac ac supply?
Asked In :-
Right Answer:
In a Variable Frequency Drive (VFD), we do not give direct AC supply because VFDs are designed to convert DC into variable frequency AC to control the speed and torque of motors efficiently. Direct AC supply would not allow for this control.

Ques:- what is the role of commutator in dc motor
Asked In :-
Right Answer:
The commutator in a DC motor reverses the direction of current in the armature windings, ensuring that the torque produced by the motor remains in the same direction as the rotor turns.
Comments
Admin May 17, 2020

The role of commutator in DC motor is to convert AC current produced in the coil to the DC output current....

Admin May 17, 2020

in dc motor commutator is use for the purpose of
reversal of current in every half cycle

Ques:- IN AN INDUCTION MOTOR,WHAT IS THE RELETIVE SPEED OF ROTOR MAGNETIC FIELD AND STATOR MAGNETIC FIELD
Asked In :-
Right Answer:
The relative speed of the rotor magnetic field and the stator magnetic field in an induction motor is equal to the slip speed, which is the difference between the synchronous speed of the stator field and the actual speed of the rotor.
Comments
Admin May 17, 2020

Zero speed because both fields move with synchronous speed(if the relative speed between stator and rotor field is not zero then rotor will not rotate as in the case of synchronous motor). Relative speed between stator and rotor magnetic fields is zero whereas relative speed between stator and rotor is slip speed.

Admin May 17, 2020

Slip speed(Ns-Nr)because rotor speed is not equal to synchronous speed. If rotor speed equals to synchronous speed then the induction motor will not run.

Ques:- difference between connection less and wireless network ?
Asked In :-
Right Answer:
A connectionless network does not establish a dedicated end-to-end connection before sending data, allowing packets to be sent independently. In contrast, a wireless network refers to a type of network that uses radio waves or infrared signals to transmit data without physical cables.
Comments
Admin May 17, 2020

if its wireless network then data or information is passed
through signals and so network is created.but
connectionless network means its no network orno connection
between two systems.so its of no meaning.

Ques:- Y Electrical engineerig mainly the supply as sinusoidal otherthan non-sinsoidal?
Asked In :-
Right Answer:
Electrical engineering primarily uses sinusoidal supply because it is more efficient for power transmission, reduces losses, and allows for easier generation and transformation. Sinusoidal waveforms also minimize harmonic distortion and are compatible with most electrical devices.
Comments
Admin May 17, 2020

ans
1.
sinusoidal functions are easy to analysids
2.
any non sinusoidal function can be transformed into
sinusoidal functions according to FOURIER THEOREM
3. in especially Electrical engineerig we r using
mainly the supply as sinusoidal otherthan non-sinsoidal
because all elctrical circuits have only r,L,C as passive
elements.for finding current in a inductor for a given
sinusoidal a.c supply we have to calculate through
integration of sinusoidal input which gives again as
sinusoidal.however, with some phase isplacement.Simmillarly
for capaxcitor also to find current from sinusoidal input
voltage we require differentiaton, which gives again as
sinusoidal.however with some phase displacement

Admin May 17, 2020

because sinusoidal wave have a single frequency.

Ques:- why is trnsformer rating in kva
Asked In :-
Right Answer:
Transformers are rated in kVA because their output is based on the apparent power, which includes both active (real) power and reactive power, and kVA does not take power factor into account.
Comments
Admin May 17, 2020

in transformer there are losses presents which are core and
coper lossess,both of these losses are the function of
ohmic current and ohmic voltage.ultimately output of the
transformeris dependes on these losses which is the
function of volt and ampere and these losses are in 'k'.

Admin May 17, 2020

transformer is the device which convert A.C. current to the
D.C. current .during transformation of A.C. TO D.C. the
mechanism of voltage changes in cosine waves. and during
transformation some losses as (magnetic losses)produced .so
according to ohm's law its rated in volts but in transformer
large capacity voltage passes so it rated in "kva".

The GATE (Graduate Aptitude Test in Engineering) is one of the most prestigious exams for engineering and science graduates in India. Jointly conducted by IISc and the IITs, GATE serves as a gateway for postgraduate education (M.Tech, MS, Ph.D.) and recruitment into top Public Sector Undertakings (PSUs) like ONGC, IOCL, NTPC, and BHEL.

GATE evaluates a candidate’s understanding of core concepts, problem-solving ability, and aptitude in their respective engineering discipline. The exam comprises multiple-choice and numerical answer type questions across subjects like Electrical, Mechanical, Civil, Computer Science, and more. It also includes a General Aptitude section to test reasoning and verbal skills.

Preparing for GATE requires in-depth knowledge of undergraduate subjects, regular practice, and familiarity with previous year question patterns. Many aspirants enroll in coaching programs or follow structured self-study plans with standard books and online resources.

A good GATE score opens doors to top IITs, NITs, and research institutes. It also enhances career opportunities in core technical roles and boosts one’s resume in both private and public sectors. It’s a rigorous but rewarding path for engineering aspirants.
