Q$\mathrm{.}1$ In general, when comparing BJT and MOSFET transistors, three main differences:

A$.$ The device that depends more on geometry $($width$,$ Length, etc.$)$ is BJT

B$.$ The device is capable of higher amplification is MOSFET

C$.$ The device that dissipates no power at the input $($zero input current$)$ is MOSFET

Q$\mathrm{.}2$ Which of the following is not opportunity to do the project?

A$.$ Demand of the product

B$.$ Emerging markets

C$.$ Lot of Manpower

D$.$ Favorable exchange rated $($correct$)$

E$.$ None of these are Organizational opportunities

Q$\mathrm{.}3$ When using the method of symmetrical components, which of the

following statements is most nearly correct

a$)$ The three zero$-$sequence current phasors are equal in magnitude and displaced by $1200.$

b$)$ The three positives sequence and the three negative$-$sequence current phases are

all equal in magnitude, but have opposite phase.

c$)$In a wye$-$connected synchronous Generator, the voltage drops through the

neutral grounding resistor, R is equal to V$3$ Iq R$,$ where Iq is the zero$-$sequence

current.

d$)$ Positive$-$Sequence and negative$-$sequence currents cannot pass through the

neutral grounding resistor in a wye$-$connected generator.

e$)$ a and b

Q$\mathrm{.}4$ The room amplifier in a wireless system amplifies

a$)$ The baseband signals

b$)$ The modulated signal only

c$)$The encoded and modulated signal

d$)$ The received signal

Q$\mathrm{.}5$ An important step in the software lifecycle is testing. one type of

testing is integration testing. Which of the following is not true concerning

integration test?

a$)$ Integration testing is employed to integrate separately tested pieces $($correct$)$

b$)$ In a top$-$down integration test, testing begins at the top levels to see whether the

overall logical design works and the interfaces between modules are correct

c$)$In a bottom$-$up integration test, testing begins first at the lowest$-$level sub$-$programs.

a test driver is used to set up the testing environment by declaring and assigning

initial values to variables and then calls the subprogram to be tested

d$)$ In integration testing. Either a top$-$down or a bottom$-$up approach is selected to

complete the test.

Q$\mathrm{.}6$

Which of the following statements best describes how a power transformer

to all losses vary with kVA Ioad?

a$)$ Losses are linearly proportional to load

b$)$ Losses are proportional to the square root of the load

c$)$Losses are proportional to the square of the load $($correct$)$

d$)$Losses are proportional to the square of the load plus a constant

Q$\mathrm{.}7$

For an inverter op$-$amp, what will be the equivalent output resistance?

a$)$ Relative forward resistance

b$)$ Infinity

c$)0$

d$)$ Same as the input resistance

e$)$ None of the above

Q$\mathrm{.}8$

To minimized loading effect use?

a$.$ Resistance

b$.$ Capacitors.

c$.$ Inductors.
