Electronics Engineering

Electronics Engineering is a branch of engineering that deals with practical applications of electronic components, devices, systems, or equipment. Electronics are devices that operate on low voltage sources, as in electron tubes, transistors, integrated circuits, and printed circuit boards and use electricity as part of its driving force.

What applications would prefer the bipolar junction transistors over the field effect transistor?

bjt is bipolar device whr fet is unipolar....fet is input resistance thts y fet gain is less compared to bjt.....

The applications that will prefer bipolar junction transistors to field effect transistors are applications that require fast switching.

How do you increase a voltage regulator from a 6v generator up to 8v to charge an 8v battery?

Without knowing what you have for a regulator, I can't say this will help. I did one last spring for a friend on his old antique boat. It is a 6v system which we changed to 8v (positive ground at that).

This regulator is on a generator, not alternator, probably same as you, basically a small metal box with a relay inside. The premis of this regulator is the spring tension is just so that at about 7.5 to 8 volts, it would trip and disconnect the generator. Simply adjust the tension so it trips at a higher voltage. You will need a very accurate volt meter, preferably digital. Also remember your target isn't actually 8 volts, 10 is probably close enough. 8.8 volts is static charge, I think 9.2 is operating charge so 9.6 or so would be peak voltage under charge (a 12V battery will show 14.4 sitting and about 15 while under charge)..

This worked great for us, doesn't show signs of boiling the battery but does keep it at peak..

Why quadrature modulation is used?

The aim is to increase capacity of the system as the signal can be represented using different phase angles as well as amplitude.

Does 2002 dodge 1500 have circuit board in the taillight?

yes the taillight does in fact have a cicuit board. Once you take off the two bolts to remove the entire fixture the circuit board is the long plastic piece with the 4 screws holding in your 3 light bulbs

In a series connection if one component fails the whole circuit fails?

Yes. Open circuit.

A: It depends on the failure type a short will not necessarily make an open circuit but rather a non functional circuit.

What are the differences between the LaCrosse Analog Wall Clock and the LaCrosse Radio-Controlled Wall Clock?

The major differences between the LaCrosse Analog Wall Clock and the LaCrosse Radio-Controlled Wall Clock are subtle. While both clocks feature displays with accurate designs, the analog wall clock provides a variety of benefits including automatic updates for daylight saving time, temperature ranges, humidity ranges, and four time zone settings. The Radio-Controlled Wall clock on the other hand offers much of the same features but with a digital view with enhanced features such as an automatic focus for projection and transmission ranges for up to 90 feet.

Where did Radar drink?

Radar would enjoy a grape Nehi at Rosie's Bar. He would also have coffee at the mess tent.

Does a transformer draw a lot of current when first connected to a source?

Yes it does as it is an Inductor and an Inductor needs to build up a magnetic field. It is called INRUSH current.

What is the difference between AC and DC in terms of oscilloscope?

One is sinusoidal through the zero point i.e. alternating current, the other would be a flat line at whatever the current value was i.e. direct current

Differences between geo meo Leo heo?

they are types of orbits of the artificial satellites:-

Low earth orbit (LEO): about 160 Km to 640 Km above the earth, so the delay is very small and the losses is small too.

Medium Earth orbit (MEO): 1600 to 4200 km above the earth, and uses for navigation communications like GPS.

Geostationary orbit (GEO): about 36000 Km above the equator, the delay and losses are greater, but the advantages is more coverage (it covers 40% of the earth) and there no nedd to track the satellite, so the earth terminal is cheaper, but the GEO is more expensive than MEO and LEO. GEO uses for Satellite TV Broadcasting.

What are the advantages and disadvantages of microwave radiation for heating a room?

The advantages and disadvantages of microwave radiation is that it is extremely harmful to humans and living things in general however it is very useful.

What is the function for tantalum capacitor?

the same as any capacitor

tantalum has a very high dielectric constant so these are smaller physically

the electrolite is solid so the capacitance is very stable

Is it possible that you use motor as a generator input and electricity of the generator provide to a motor as a input?

If I'm understanding the question, you are proposing using one motor and one generator, and have the motor spin the generator up to speed, and have the generator attempt to supply power to the motor.

The answer is yes, you can do this, but you will be losing energy, not gaining it. The motor and generator's efficiencies are less than 100%, so once you remove the outside source they will slow down until they come to a complete stope, without any other load connected other than themselves.

Is fmcw radar a doppler radar?

An FMCW radar may make use of Doppler, but it doesn't necessarily.

What in a series circuit is constant?

Nothing about a series circuit is necessarily constant.

You may be thinking of the current, which is the same number at any point in a series circuit.

That doesn't mean that it can't change. But if it does change, it'll change at every point, and

still be the same number everywhere in the series circuit.

What is the Difference between Si and Ge diodes?

The significant operational difference between a Si diode and a Ge diode is that Si diodes have a knee voltage of 0.7V needed to allow current flow and Ge diodes have an operational voltage of 0.3V to allow current flow.

What are the importance of semiconductor in industry?

It's where electronics begin. You cannnot have any electronic device without having a chip inside it, and without the heros of this industry we would be far behind where we are in the digital world of today.

Can you use a poke radar in water?

No Because if you use it in grass the grass moves. But if you could use it in water how would it work?

Can you cut and shorten a parallel connected string of lights?

A: Sure even to a one to one level. The problem will become evident when the power will increase linearly as the load evidently is increased by cutting and shortening that is true if the input power level remains the same

Why are discharge resistors connected across large industrial capacitors?

A: Discharge or bleeder resistance are there for only one reason to bleed the charge when the power if off and unless there is a paths for those capacitors to be discharged the power stored there can be lethal to humans or detrimental to the circuit
