The problem with floating inputs is that electrical noise in the line could trigger the input without user input. This can easily be avoided with a pull-up or pull-down resistor.

A static magnetic field can exist in a good conductor. When the conductor carries current, it produces the flux which can exist inside the conductor. Due to this flux, magnetic field and intensity at a point inside the good conductor.

A clipping circuit works by the switching action of a diode when it is used in a circuit with a source voltage that changes polarity.

In the forward direction, the diode's voltage is added to any dc value that is in series with it. If the source voltage is greater than the dc value at a particular instance, the diode will limit the output to the dc value. Otherwise the output voltage will equal the input voltage.

A shadow wave is a phenomenon where light is blocked by an object, creating a dark area or shadow behind it. This occurs when light rays are unable to pass through an opaque object, resulting in the absence of light in that particular area. Shadow waves are a common occurrence in everyday life and can be seen when an object blocks a source of light.

Glass is an electrical insulator. It does not conduct electricity. Many insulators made for power transmission lines or in the older days telephone or telegraph insulators, are made out of glass due to their superior insulating qualities.

No, compound semiconductors do not behave as intrinsic semiconductors because they have different band structures due to the combination of different elements. Compound semiconductors have unique electrical properties that make them suitable for specific applications that require different performance characteristics compared to intrinsic semiconductors.

Crushing a ceramic capacitor for FTIR analysis can be done by placing the capacitor in a mortar and pestle and grinding it into a fine powder. Ensure that the ceramic material is completely broken down to achieve a homogeneous sample for FTIR analysis. Wear appropriate protective gear to prevent inhalation of particles during the crushing process.

It sounds like a math trick because the electron cannot exist in the middle of the band gap. The trick would be that it would take an infinite amount of energy to excite the electron to the middle of the band gap.

The voltage drop across a resistor is equal to the resistance times the current flowing through it. If you do not have a constant current load you cannot use a resistor and must use an active solution. Please read up on ohms law before continuing with your project.

You can only reduce amperage in a circut by reducing the number or size of devices plugged in to it. To make it easy, imagine you have a 120watt light bulb. Given your household voltage is normally 120v this would draw 1 amp, (volts X watts = amps). fifteen of these bulbs would draw 15 amps, the size of a commonly used circut breaker. The sixteenth light bulb added to the circut should trip the circut breaker or fuse to protect the wiring from overheating. If you chose to use 60watt bulbs instead you should be able to burn 30 of them before th breaker trips. Likewise if you needed 240watt bulbs, that same circut could only carry 7 of them.

Solar inverter modifies the electricity from the solar panels and changes it to power the appliances in a house. This inverter has a special feature that can adapt for use with photovoltaic arrays.

Radiation loss refers to the energy emitted by an object in the form of electromagnetic waves, such as heat or light. This process is often associated with the cooling of an object as it releases energy in the form of radiation.

Frost shattering is due to temperature fluctuations. During the day when the temperatures are warm, water settles into cracks in rocks. At night the water freezes and causes the cracks to widen. Eventually this causes pieces of rock to shatter from the main rock, this is called frost shattered peaks.

low frequency fatigue is caused by small muscle tear and it takes time to repair this destroyed muscle

high fatigue is cause by lactic acid accumulation that is why it takes time before the body converts it to glucose or other form by liver, heart or kidney

The name of the north star is Polaris. As the brightest star in the constellation of Ursa Minor it is also called alpha Ursae Minoris. It is actually a multiple star comprised of Polaris Aa, Polaris Ab and Polaris B.

I grew up without a television and don't have one now, so I feel like I have some expertise on the subject. Television does some things that unify and bring people together because everybody in the country can watch them together--like when we landed on the moon, or a president gets inaugurated, or when we all watched the aftermath of Katrina together. I suppose those things are good in a way. Information can be transmitted instantaneously, that's good, as in the case of an oncoming catastrophic storm. Those things we might not be aware of without television.

If we didn't have television, I think we could easily argue that terrorism would be greatly lessened, since terrorists rely on "the whole world watching" to shock and destroy (Munich Olympics in 1972, and of course 9/11, staged for the morning news shows). If we didn't have television, people would spend more time doing other things, like, maybe talking to each other or reading or engaging in other hobbies. Some people would argue that if we didn't have television, we'd all be slimmer and healthier. If we didn't have television, we would have lost a major means of advertising to the American public, and that might really do nasty things to our economy. If we didn't have television, school children would see about 10,000 fewer violent acts per year. If we didn't have television, our landfills wouldn't be full of old, useless sets. The best way to find out what life would be like without the television is to turn yours off.

This question makes no sense as written. However, maybe it will help to know that for a given load if you increase voltage the current increases proportionally and if you decrease the voltage the current decreases proportionally. Ohm's Law says Voltage = Current x Resistance.

Germanium diodes are more expensive than silicon ones, germanium is harder to process, germanium cannot be used to make integrated circuits (while early prototype integrated circuits were germanium the wiring between the integrated components cannot be integrated making it too expensive for production), germanium cannot operate with a junction temperature above 60C (silicon will operate up to 150C), and its reverse leakage current is greater. However! Germanium diodes have a lower forward voltage drop than silicon ones do, so they're better for some applications, like radio frequency detection.

A positively charge body is deficient in electrons (electrons are negatively charge, so a lack of them results in something being positively charged).

In a series generator, the voltage output is directly affected by the load. As the load increases, the voltage output decreases due to increased voltage drops across the internal resistance of the generator. Conversely, reducing the load will result in an increase in the voltage output.

No, a cellphone speaker cannot emit a high frequency tone powerful enough to kill a person. High frequency tones emitted by cellphones are limited in power and intensity and are not harmful to humans.

The types of tissue that generate electrical signals would have to be examined on a case-by-case basis. There are a number of creatures that are bioluminescent, that generate light (which is electromagnetic radiation). And there are electric eels and electric catfish that generate a "pulse" of electrical energy. Additionally, many organisms have nervous systems that generate electrical signals as part of their nerve function. The variety of tissues that generate electrical signals varies widely depending on what kind of electricity or electrical signal is being generated. These tissues can generally be studied only individually, as the mechanism of electrical generation by one may be significantly different than that of another.
