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 is the Applications of dip brazing prosses?

It is often used in fabricating structures out of aluminum. Antennas and machinery enclosures are examples I am personally familiar with. Aluminum is tough to braze any other way, because you have little latitude with temperature. The brazing alloys that work with aluminum start to flow at temperatures that are very close to destructive for aluminum, especially in the presence of atmospheric O2. Temperature in dip brazing can be very tightly controlled.

Explain the working principal of LVDT with a suitable diagram?

the physical energy is converted into electrical signal it's the principle of LVDT

What is the definition of unipolar pulse in digital electronics?

Unipolarpulse waveforms consist of an applied anode potential during the on-period and an open-circuit potential during the off-period.

What is the max e1 ckts on a ds3 circuit?

This question actually is unanswerable.

A DS3 or T3 has 28 DS1 or T1's.

A E3 has 16 E1's

There is no comparison between the two. A DS3 moves data at 45Mbps an E3 is 34 Mbps. they can not directly connect together. This includes their subrates. An E1 can not connect directly to a T1 without a converter.

Why doesn't LC circuit exist?

even though a resistance is not connected in a circuit, it would practically have small resistance due to its components.so practically a LC circuit dosent exist..only a RLC circuit exists

Why bridge rectifier is prefer over center type rectifier?

it is more preferable over center tapped rectifiers because you dont have to use special centre tapped transformer that has larger secondary windings thereby reducing the size and cost

it also has another advantage by the use of 4 diodes i.e. peak voltage sustained by each diode is half of that sustained by the diodes in center tapped system that uses only 2 diode. thus lifespan of bridge type rectifier is more.

Can you connect a 8 ohm speaker for a amp designed for a 4 ohm load?

You can, but the available power will only be about half of rated, and the frequency response will be slightly different. Better would be to connect two 8 ohm speakers in parallel, making an equivalent 4 ohm speaker.

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.
