Electronics Engineering Interview Questions

Yes, Gas need to be ionized, like in fluorescent lamps, flash bulbs etc.

No

Biasing is the predetermined voltages and currents given to the transistor to set an appropriate operating point in the active region of transistor.For a transistor to work as an amplifier it must be ...

When electrical energy applied to the pn junction it cancels the potential barrier is called biasing.

RESISTANCE:It is the property of the material by which it opposes the flow of current through it. the resistance is denoted by r and measured in ohms.

INDUCTANCE: It is the element in which energy is stored in the form of electromagnetic field. The inductance is denoted by l and measured in Henry

of course inductor restore the temporarily electronics current but on the other hand resistance only reduce the current actual position.

8086 has 20 address lines and 16 data lines and supports HARVARD architecture as compared to 8085 which has 16 address lines and 8 data lines, so 8086 has higher index and thus accessing large memory, also the operating speed of 8086 is greater due to presence of instruction queue.

8085 8 bit mc and 8086 16 bit mc and 8085 don't have instruction Que and 8086 have instruction queue

If u have a good fluency in English you can go for voice otherwise ...

Different waveforms have different applications.in some applications we require digital signal where we require only on or off state or discrete output but in some applications we require continuous o...

2m+2n

Voltage at the non-inverting input terminal of an op-amp can be realistically assumed to be equal to the voltage at the inverting input terminal

because in the op AMP this uses th DIFFERENCE of input applied..

the input impedance is very high so there is no current flow from the terminal

AS ohms law


if theoretically r= infinite then

i=V/R
i~0;
n in ground there is 0A current

so it is called as virtual ground

440v is the line to line voltage, there is 230v for phase to neutral. So both 230, 440 volts is common operating voltage recommended by Indian standard rules. If our application required 660 volts, Just we step up the voltage by suitable step up transformer.

In 3 phase power electrical systems there are 3 phase in and 1 neutral because neutral is common for both in and output sources. 3 Phase electrical In used for high wattage expenses.

in india we are using as altration by line i.e PAL system...

this system is also used in British..

It is PAL SYSTEM.

Edge triggered flip flop are of two types 1. Positive edge triggered flip flop-In a pulse train when ever the input is changing its state from negative edge to positive edge then it will be consider...

Edge triggered Flip flop means that the input is neg to post (0-1) but level trigger means input is post to neg bit (1-0)

NO junction in conducter

No there is no junction in conductor. because its not semi-conductor. only semi-conductor contains junction

We can use GUI testing techniques and we can use also use automation tool for stylish applications.

Correct answer is motherboard.

My answer is 4. Cache memory

2421 code is a weighted code and gray code is an unweighted code.. so, they must be 2 different things

It should go like for eg..for 1010 d conversion will be 1111..n for 1001 d conversion will be 1101

Semiconductor devices are made with semiconductor materials like Silicon, Germanium ,having the electrical properties of both Conductors and insulators. For Example pn junction diode, BJT, MOSFET, SCR etc. They are mainly used in Switching and Amplification purposes.

The semiconductor devices are the devices which stand in between the insulators & conductors.
It have medium amount of electrons.

8085 mc follows complex instruction set computing with Harvard architecture.....
