It means your not available to chat because your not lodged in.

Who invented the triode ampliflier vacuum tube?

That's very tough to define. As far as I can tell it was Irving Langmuir at GE in 1915. Lee De Forrest was experimenting with them also, but I don't think his were in production before the GE version.

No. You just need to check some references.

See, for example, 70 Years of Radio Tubes and Valves, Stokes, J.W.

On page 5, Stokes states that Dr. Lee de Forest supplied Audion triode tubes for a 1906 installation at Key West, in Florida, well before Langmuir.

It's true that the de Forest Audion was unreliable and unpredicatable in service, as de Forest mistakenly thought that some gas was essnetial to Audion operation.

Langmuir's work on highly-evacuated "hard vacuum" valves *was* essential to the development of the triode and all of its successors.

Where can one purchase electronic signs?

Electronic signs are not easy to find in common stores found in most areas. But companies like ElectronicSigns and Bright Neon Signs have a large selection of signs that you can customize online then have shipped directly to your business.

What do you call a diode installed across a coil with the cathode toward the battery positive?

A diode connected in this way is a flyback diode or kickback diode. There are some other names that may be applied. The diode is a protection device. When power to the coil is discontinued, the electromagnetic field around the coil will collapse. The collapse of that field will induce a voltage, and this could expose circuit elements to "kickback" from the field collapse. The polarity of the induced voltage will, however, forward bias the diode, and it will conduct current for an instant. The inductive kickback of the coil will thus be damped by that diode.

How do you test TV remote control signal light?

Use a camcorder. Put the camera in "Camera" mode (for recording) and look through the camera's viewfinder while aiming the remote directly into your line of sight. Make sure the remote is close enough to see the little signal diode through the darkened lens filter on the remote. Press any function key on the remote. You should be able to see a barely visible flicker of bluish light coming from the signal diode. If you cannot see this flicker, try adjusting the shutter speed. If you still cannot see the flicker, try other buttons. If you still cannot see any flicker, the remote is "Not Responding" (computer humor). This can be done as the flicker is so faint, that the human eye can barely detect it. Try it! Turn out all the lights in the room and hold the remote close enough to your eye to still be able to see the signal diode clearly and you MAY see a faint flickering after a button has been pressed. Try the Volume or Channel button. These buttons have a "loop" effect which causes the button to continuously reactivate the function as long as the button is being held down.

How do electronics work?

There are a number of components in any circuit and their job is to restrict the flow of electrons and reduce the current or voltage flowing by converting electrical energy to heat. In other terms, electronics control the electrical circuit. Electric charge is nothing but the flow of electrons from one object to another. The working of the microwave is the example of how electronics work. In a microwave, electricity provides the power that generates high-energy waves that cook your food and electronics controls the electrical circuit that does the cooking.

Which has a higher resistance a 5w lamp bulb or a 25w lamp bulb and how many times?

As per the formula for power (Power (Watt) = Voltage (V) x Current (i) & Resistance (R) = V / i), 25w lamp bulb would have higher resistance compared to that of 5w lamp bulb.

Where do you put the batteries in your vetch 80-61100?

at the bottom of the computer there is a little cube then you put in two AA batteries in

What are some coping strategies you can use to break the hold of your phone and other forms of electronic intrusion?

Go for a walk or even adventure the outdoors. I know my favorite thing to do when I am trying to prevent myself from doing something is listening to music and either singing or dancing

What are the characteristics that change when 50 Hz wave get fully rectified?

When alternating current of any frequency is fully rectified, both halves of the wave are converted to direct current and utilized. Half-wave rectification is when half of the wave is ignored. So the main characteristic that is changed is the shape of wave by flipping half the wave over to the same side as the rest. But it does not flatten the peaks on the wave without additional filtering.

Which is easy electronics engineering or electrical engineering?

Neither.

Why current is directly proportional to voltage?

Ohm's Law: Current = Voltage times resistance, hence current is directly proportional to voltage.

Wiring sound and light define the following polarity of the screw colors brass bronze silver green?

Brass (or bronze) is the "hot" wire, (Black, red, or blue) silver is for the neutral (the white wire) and green is for, well, the green or bare wire

How do you fix Memory Leak on Windows?

i had the same problem just go buy some duck tape and tape it up it should stop leaking

Can I buy an HDMI to DVI adapter at any electronics store?

There are several good companies which stock a good quality hdmi to dvi adapter, many of them also have online shops so you can order by post if you wish. You can also check the local forums and ask for hdmi to dvi adapter recommendations, and for a price check, one of the comparison websites will prove useful.
