Can Anybody Explain to Me How I Could Instal Interior Underglow(led Lights) to My Car W/o the Cigare
Just run wires straight from the battery for positive and negative1. doesn't ohm's law applied to every thing? [closed]Ohm's law specifically deals with the relationship between direct voltage, current and linear resistance in the form V = IR. For AC circuits it can be generalised to V =IZ where Z is a complex impedance.Transformers convert an alternating primary current into an alternating magnetic field in the core which is then converted back to an alternating voltage in the secondary coil - This effect was demonstrated by Michael Faraday. (Google Faraday, transformer) He showed that the input and output voltages where connected by the turns ratio. For a 100% efficient transformer we get:We must also apply the conservation of energy rule - you can not get more out than you put in. Given that there will always be a loss of energy (heat, noise etc.) the power output will always be less than the power input. always greater Iin * Vin > Iout * Vout (Power in is always greater than power out)If a load is connected to the secondary coil a current will flow. The transformer will react by increasing the primary current in line with the transformer turns ratio in order to maintain the power in to power out relationship.A filament bulb works by heating the filament to a high temperature. Most of the energy used is radiated as heat rather than light, making this type of bulb inefficient. The colour of the light is determined by temperature. (Google black body radiation, Stefan-Boltzmann law).'Energy saver' bulbs use a gas discharge lamp and phosphor coatings to produce light. (Google - Electric discharge in gases) The current passing through the reduced pressure gas excites electrons directly which then jump from one energy band to another before decaying and emitting a photon. (Google - Planck-Einstein relationship) This means that they generate light energy directly without the need to generate lots of heat energy. This makes them more energy efficient that filament bulbs for the same power input. Hence the term 'energy saver.'LED lights (Google band gap, LED) use a similar principle (electrons jumping from one level to another) through a PN junction in a semiconductor.This is more efficient than gas discharge lamps giving LED lighting more lumens (light output) per watt.2. Sleep Peacefully at Night: How CCTV Keeps Businesses Safe in the DarkNight vision cameras were once the standard for the military, scary movies, ghost hunting, and those energetic wildlife enthusiasts. Nowadays, nearly anyone can make use of the technology, especially when protecting business properties. Night vision technology is instrumental when it comes to business security. Several burglaries and attempted break-ins occur at night, and there are many things you can do to improve your business's nighttime security. For example, installing motion-sensitive lighting and night vision CCTV cameras are the most feasible solutions to help you sleep peacefully at night. CCTV keeps businesses safe. Several surveillance cameras are motion-sensitive and can send alerts when movement is detected. You will instantly know if someone is trying to access your facility without your permission. Yet, typical cameras can not see in the dark, so they can not always pick up motion and send you the essential information you need. This is where the night vision comes in. So, how does it work? Infrared, or IR, is the most common type of night vision popular in outdoor security cameras. This kind of technology is brilliant; it can flood an area with light invisible to humans, but the camera's lens has no trouble picking it up. A possible intruder would see complete darkness while the camera would film in near-perfect clarity using the IR light produced. Humans cannot see IR light because it has a longer wavelength and frequency than normal light that's visible to the human eye. Red is the color with the longest wavelengths visible to humans, and infrared means 'below red'. On most infrared cameras, you will see a unique configuration of bulbs being used. Higher power infrared LED lights are positioned around the outside of the camera lens. IR is used for several different filming purposes and is typically used for wildlife filmmaking. This is because the invisible IR light does not bother the animals as they cannot see it. This makes for a very secretive, nocturnal filming opportunity. Another type of night vision filming technology exists. It's not something commonly used in homes, businesses, or even professional security cameras. Image intensification tubes are used in night vision goggles to collect and significantly intensify all available light, including infrared light. This allows the wearer of the goggles to see in low-light situations or even in total darkness. When an area appears to be completely pitch black, it never truly is. There usually is a source of light, even if the human eye finds it difficult to spot. The light entering the goggles is converted into a green tint, making people's eyes shine brightly in the image created, as human eyes are most susceptible to green light. Night vision goggles that employ this technology are most likely used in military and law enforcement operations. Night vision is instrumental in security cameras since it allows the camera to detect motion more adequately, thus picking up movements by an intruder with ease and alerting you immediately. Although, there can be occasions where you (or the police) cannot get to the location in time, and the intruder makes a getaway. If this happens, your night vision cameras become even more valuable. The clarity of the footage that they can record with IR light and night vision technology means that perps can be more easily identified and arrested. The footage then becomes very useful as evidence. In contrast, a standard surveillance camera would pick up a blurry image in poor lighting or absolutely nothing at all in the pitch dark. Most night vision CCTV cameras also come with extra features and functions to further enhance the footage's quality and clarity. These include: Capture Faces, Number Plates, Etc. With This Technology With this new technology, you can capture faces, license plates, and many other details to provide to the authorities. A lot of activity takes place under cover of darkness, and night vision cameras can help you keep a sharp eye on what is going on. This is very useful in legal cases, investigative matters, or just to provide everyday proof of suspicion.3. Why paintball marker is better?1. They are all under 2 lbs. You would never be able to tell the difference, though. 2. Egos are technically more air efficient but efficiency among high ends nowadays is such a dead topic because they are ALL more efficient than anyone could possibly care. 3. Better settings? Like ease of settings? Because they all have the same tourney modes. Egos are probably easier because they have an LCD screen instead of LED lights. 4. They are all easy to maintain but Egos are a little faster in the maintenance dept (less o-rings to lube). 5. I prefer spool valve guns over poppits, so i like the DM's more. Never shot an NT but i can not imagine it feeling too much different than a DM.
