Does the heating pad on the itouch work?

I have the newest one and it doesnt have a "Heating pad" And the new ones have more than the old..so And i have the New one...Hope this helps!

Why is my television showing green people?

It probably means that you need to adjust the color and tint controls. Otherwise, you have an electronic problem that is preventing the red and blue electron guns from working, assuming an older television. In a CRT television, the CRT could be shorted out internally, or there could be problems on the circuit board plugging directly into the picture tube.

Is a NTC thermistor different from PTC thermistor?

Yes, NTC stands for Negative temperature coefficient. This means the resistance goes down as temperature goes up.

A PTC has a positive temperature change. As temp goes up, the resistance will increase also.

Where is the battery charger in Dexter's Laboratory?

If the robot is behind the clock then put on your ex ray glasses and look under the girls bed and the battery pack should be there !!!

What color eyes does olly murrs from x factor have?

He has Brown eyes although it is difficult to see in his phots and he probably wears contact lenses most of the time. P.s it's olly murs not olly murrs.

What is the importance of the electron?

The electron is of great importance.

Electrons are the little things that circle atoms.

Their configuration around any given atom basically determines how that atom reacts with other atoms to form bonds etc. and which atoms it will reactt with.

They're also what makes up electricity (electrons flowing from one point to another).

What is the difference between electrical and electronics measuring instruments?

In the time that an electronic field was invented by Thomas Edison in 1883, electrical devices already exist 100 years ago. The difference between this to devices depends how it manipulates electricity in the field of work, electrical take the electric energy then transform it in the form of heat, light or motion while the electronics are designed to manipulate the electrical current and it also is doing so much more.

Which brand of battery is known for the coppertop?

The Duracell battery brand is known for its copper top. The Duracell brand was introduced in 1964, although the company had been making mercury batteries for military applications for decades.

What does uf mean in electronics?

With the description you made uf might refer to microfarad, which is a value of a condensator.

What is the present cost of FPGA in market?

FPGAs come in a wide range of prices,
from under $10 (in ones) for a small, slow FPGA with around 50,000 gates
to well over $1000 (in ones) for a large, fast FPGA with over 1,000,000 gates.

What was the problem that the developers of the transistor were trying to solve?

To amplify an electrical signal you need a device that gives a voltage or current gain.

The crystal diode had been known about for 30 years before the invention of the thermionic diode and then triode by Lee de Forest. These glass tubes with glowing filaments and high voltages were fragile and wore out. In the 1950's the Bell lab scientists looked again at the crystal diode and worked with a bar of pure Germanium. They were able to push this semiconductor into being an insulator or good conductor by doping the Germanium with Indium or Arsenic. The doping gases made P or N type Germanium and by arranging a sandwich of PNP germanium with layers known as Collector,Base.and Emitter. The base region at the centre of the sandwich was made very thin indeed and was the point at with the low level signal was injected. The biasing of this base region with a small dc voltage could turn the Collector/Emitter into full conduction or,if lowered very slightly,into a near perfect insulator. With this small bias set to make the collector voltage just starting to fall an AC signal was superimposed on this steady dc bias. The signal on base now appeared at the collector,inverted and amplified by a significant amount. By feeding a fraction of the output back into the base a positive feedback loop was created and the first transistor phase shift sine wave oscillator was born. This point contact germanium transistor still exists and Bell scientists Bardeen,Brattain and Shockley got the Nobel Prize for it's invention.This invention paved the way for today's wired world and is the most significant invention of the 20th century.

How electronic gas lighter works?

Electronic gas lighters work off mains supply or battery packs and produce an electric spark which travels down a high tension wire to a sparker, situated next to the gas burner. When the burner is letting off gas and the spark reaches the sparker combustion takes place as long as there is adequate air.

Clipper and clamper circuit?

clipper circuit is used to remove some part of wave form(positive part,negative part or peak)...

clamper circuit is used to shift the wave form (up or down) ....

What is mean by lumped element in electronics?

lumped" means that the dimension of you ckt element is much smaller than the wavelength of the signal passing through it. Therefore, you can treat your ckt element as a lumped unit (against the wavelength), and do not have to worry about wave propagation phenomenon "within" your ckt element. The opposite of "lumped element" is "distributed network."

Typically, in low-frequency ckt/network, since the frequency is low, therefore, the wavelength is large (wavelength = propagation speed(usu. speed of light) / frequency ), so most elements can be treated as lumped. However, as frequency goes higher and higher, the wavelength becomes shorted and shorter, the wave propagation effect WITHIN the ckt element becomes more and more pronounced.

Why it is not a npnp diode in place of pnpn diode?

I think there is no difference between PNPN diode and NPNP because if u look at the basic structure of this diode from anode side it is a PNPN diode and if u look at it from the cathode side it is a NPNP diode.......actually it is a four layer silicon device with two terminals...it consists of 3 junctions..it acts as a switch during forward bias condition.....

i hope it's the correct one....if I am wrong please post the correct answer so that i can correct myself.....
