Worlds longest lasting light bulb?

Probably a LED bulb, because it has no wear-out components.

For example, a tungsten bulb filament gets thinner and thinner because tungsten sublimes off the filament and plates out on the glass envelope. CFL bulbs have hot cathodes with the same problem.

LED bulbs only fail due to manufacturing defect or misuse.

Answer:

The current holder for longest lasting bulbs is The world's longest lasting light bulb is the Centennial Light located at 4550 East Avenue, Livermore Clifornia. Its claimed that the bulb is at least 110 years old

What is a denester?

The best example that tells a denester is Wesley Sneijder. He takes the ball and sends to the adress. This is the logic what a denester does.

What is an electronic report?

An electronic report indicate that the total brief description about any object in electronics format . it is used in bank airports and several other places.it is highly reliable and the data is not volatile and you can send it to any place with the help of internet.

What are the characteristics of a common emitter amplifier?

There are a number of characteristics found in a common emitter amplifier. Not only are the parameters considered, but also their performance. Characteristics and performance are: voltage gain/ medium; current gain/ medium; power gain/ high; input / output phase relationship/ 180 degrees; input resistance/ medium; and output resistance/ medium.

What is the difference between a torch and a flashlight?

There is no difference. Flashlight is the American word for what the English speaking countries call a Torch. This then avoids confusion when using a camera with a flash!

What is noise immunity in digital electronics?

Noise immunity is the ability of a system to perform even when there is noise present. The higher the level of noise a system can still operate under, the higher the noise immunity.

What fails on a sony ldm 3210 power board?

The lifetime of the large capacitors is very often shortened by the ambient heat. They last for just 8 to 10 years. Some of them are not showing any changes at the outside and therefore can not be recognized as bad. So if you are not finding other failed pieces on the powerboard beginn to change all capacitors. From my experience the larger one nearest to heatsources (as alloycooler) are failing first. In my case it was none of the capacitors but one of the two relays. If it's the relay the TV does not start, you hear the clicking relays more than twice (normally just two clicks - because of the two relays connecting) and the power LED changes from constant green to red flashes. Flashes red 6times, pauses, flashes again 6times red, pauses and so on... and so on

What is the electronic symbol for a fuse?

The symbol for electronic fuse can be obtain by marking a line on paper after that remove some portion of line from middle and make a horizontal s with length of below 1CM it is the basic symbol of electronic fuse you will also found on the books.

What are the three electrical quantities?

Voltage , volts

Current , amperes

Resistance, ohms

Answer There are numerous electrical quantities, not just three. They include, current,

charge, voltage, resistance, inductance, capacitance, frequency, power, energy,

reactance, impedance, admittance, susceptance, conductance, permeability,

permittivity, resistivity, conductivity, etc.

<<>> For basic definitions of dimensions in physics, it is normal to take mass, length, time and charge (MLTQ); or mass, length, time and current (MLTI). Thus only one extra physical dimension is needed to extend normal mechanical space to include electrical quantities.

Why breakdown occurs in diode?

Normally too higher voltage burns the diode.

What are the most common electronic book formats?

The two most common electronic book formats are pdf and epub. PDF comes first because it is universally accepted on computers and most ebook reading devices.

What is an alternative method to measure the charge to mass ratio of an electron?

Modern Mass Spectrometry is the alternative method to measure the charge to mass ratio of an electron.

Discuss the branches and sub-branches of electronics?

fuzzy electronics, digital electronics, integrated circuit, analogue electronics, microelectronics, semiconductor, semiconductor devices, microelectronics, circuit design,VLSI design, embedded system

Does solder for electronics expire?

No. No quite true. NASA will recycle solder if old . LEAD is not exactly a clean metal it show oxidation if very old. Can it be used on your hobby yes of course.

What is the ticker symbol for Electronic Data Systems?

The ticker symbol for Electronic Data Systems is EDS and it is traded on the New York Stock Exchange.

Can you play Angry Birds with PSP-3000?

no you cant you can only play anngry birds on a touch screen or computer

Can you replace a 470uf 10v capacitor with a 470 25v 105c high temp radial leads capacitor for a digital tv converter box?

Yes, as long as there is room to mount the larger capacitor. A better replacement might be a 470uF 16v capacitor, which should be smaller than the 25v cap.

If necessary, insulating tubing can be put on the leads & the cap can be mounted off the board, or at an angle to the board.

Remember to observe polarity when connecting the capacitor leads to the board. Note the orientation & markings on the old capacitor before unsoldering it.

What problems can occur with soldering activities and how can these be overcome?

There are three classes of problems.

First is the health hazards from soldering fumes. At one time, solder contained lead. Heat lead enough to melt it and it generates fumes that are dangerous. The rosin flux in solder also produces hazardous fumes. Proper ventilation will overcome this.

The second is done through the use of corded handheld soldering tools, which have static electricity at their tips that can damage components. If you use corded soldering irons, get the kind with grounded tips. These ones have three-prong plugs.

The third is thermal damage to parts. Using solders with low melting points, and proper technique, will solve this.

Can a charger set on fire?

yes, my old laptop's chargers were so rubbish i had like 6 all together and my third i think sparked violently and then set on fire, only a little flame but it scared the crap out of me

What is the function of diodes?

The Basic Function of Diode is to act as a switch.

when it is ON(forward biased)it will allow the current to flow through itself by offering a low impedance in the circuit.

When it is OFF ( Reverse Biased)it will not allow the current to pass through itsel by putting a high impedance in the circuit.

A diode can also be used as a clamp, and as a detector (mixer) in an a.m. receiver.

Where can you find an electronic handheld skipbo game?

I own one...brand new a matter of fact. Anyone want it?

Yes I want it - please contact me! marleneo27@verizon.net
