What are the advantage disadvantage of using cellphone inside the?
The advantage of using a cellphone is that it is portable and affordable. It therefore makes communication easier and faster. The disadvantage is that it may lack privacy and may be very costly.
What will happen if you double the voltage across a diode?
basically a diode flows an exponential curve Vs current if you try to double the voltage drop by increasing the voltage it should self destruct
Does a frequency counter help a cb radio that much?
For CB's that are both modern and "legal" a frequency counter does not help much at all. However if you have an older radio with continuous tuning (dial with a needle) or are tuning "out of band" (using an illegal modified CB) you may find a frequency counter very useful. No,All the frequency counter does is match the frequency to the radio, to tell you how accurate the radio is, if it is a quality radio it is a waste of time for a more efficent CB radio you would want a RF meter to match the antenna to the radio, this would give you max signal when you key the mike, most of the radios that I have ever used have a signal strength right on the radio. All radios are designed to reject all frequencies except the one it's tuned to. Transmitter accuracy and receiver accuracy are both important for clear reception. CB radio uses 26-27 Mhz with a channel spacing of only 10Khz. If your transmitter's frequency is 5Khz too high and the person you're trying to talk to has a receiver that is a few Khz too low, you may not be able to talk to them at all or the sound will be distorted. All radios can be aligned. Better quality radios will not necessarily hold that alignment better. Antenna matching will affect how strong the signal is but not the frequency accuracy of that signal.
A frequency counter will tell you what frequency you are on. It does not help the average CB radio. But it does do a lot for modified cb's with extra channels. A Frequency counter also comes in handy if you are talking on side band, it helps you remember where to set the dial, and makes tuning someones signal in much easier. A Frequency counter will help if you need it. If you dont need it it is a waste of money.

Do police know if you are using a radar detector?
Several radar detector manufacturers have made strides during the past few years to greatly reduce the LO leakage from their products. This greatly reduces the range at which the Spectre RDD can detect these newer radar detector models. And, at present, there are three specific radar detector models which have virtually zero LO leakage. This makes these three radar detector models completely immune to detection by VG-2, by the Spectre, any other present technology, or any new technology which possibly could be developed during the next 5 years or so.
How do you make a computer joystick?
If you are trying to make a computer joystick, the way you would do it would depend on the type of signals you are trying to produce. If you want a simple digital joystick, you would use switches for each main position, and a pivot and arms to reach the switches. If you want an analog joystick, you would need to create a yoke to turn 2 sets of potentiometers (basically volume controls). A modern digital joystick might use the potentiometers and an A/D converter. Then you would have to have switches for the fire/control buttons. Then you would need the correct cables and wiring. If you create for USB, you'd need extra circuitry to make it USB compliant (and that is beyond the scope of this answer).
Is downloading fallout 1 and 2 from gametap for free legal?
Im not really sure, but a wise man once told me, "If you think something may be wrong, then don't do it" Praise to you grandpa!!!
Electricity is a Electron potential (voltage - V) and/or Electron flow (current - I). Every thing out there is made out of Atoms, where the outside of any Atom is Electrons. When Electrons flow through a medium, it causes energy to be released by those Atoms in the medium, and some energy is lost from the Electrons. This is Electric Resistance (R). This energy is released as Photons [not Protons]. Photons are the light, Electromagnetic waves, the conjugate of Electrons. Photons are perpendicular to Electrons and have a wavelength. Photons have a colour and some Photons can be seen, if their wavelength is within the human vision. The wavelength of the Photons released depends on the Energy lost by the Electrons in flowing through that medium and the various characteristics of the atoms of the medium.

How can you fix a dishwasher leak with a copper fitting?
1st you need to know where the leak is. The only time a copper fitting or brass fitting will fix a leak is in the watersupply connection.
How do you get a scratch off of a DVD?
You fix discs by using a kit with a series of abrasives, from course to light, to wear down scratches - step by step - to a smooth finish. Professional systems use multiple abrasives, consisting of different hardness and shapes (sharp to smooth). Regardless of product or system used, the key is to use a series of abrasives (more than one stage) to gradually bring the plastic back to a polished surface. If you want to remove all scratches on your disc, take a look at the 5-stage Scratch Pro repair kit. It will bring the disc back to its original shine and you will have a kit on hand to fix the next disc. Also do a search for scratch repair to see what is out there in your area. To do a targeted search, use the + sign in front of the search words +disc +scratch +repair From Merlin's Table's site… "CENTRE RING DAMAGE... The ring around the centre of the disc contains the data that tells the console player or CD player what the disc is all about. When this ring is scratched or scuffed or hazy, the disc will not register in the console. The ring is on the non-labeled (data/playing) side of the disc, around the centre hole. Look closely and you will see a small shiny band in this highly reflective area. This area and any other scratches on this side of the disc can be fixed using your repair kit."
All types of fuse work in exactly the same way. A fuse is an overcurrent protection device which protects a circuit against overload currents or short-circuit currents.
Overloads are caused when too high a load is connected, causing the supply conductor to carry more current than it is designed to carry. If this is allowed to continue, it may cause the conductor to overheat and represent a fire hazard.
Short-circuits occur when the line conductor accidentally comes into direct contact with either the neutral conductor or the earth (ground), causing a very high overcurrent to flow.
A fuse contains a metal strip, called an fuse element, which is designed to melt and disconnect the circuit in the event of an overcurrent. The higher the overcurrent, the faster the fuse will act to disconnect the circuit.
Fuses are graded in such a way that the fuse closest to the fault should operate first. For example, the fuse protecting a residential lighting circuit should operate faster than the fuse protecting the consumer unit.

What was the second telephone?
hi guys the second telephone ever invented was the telephones for the deaf invented around 1880. then was the candlestick telephone invented in the year 1900. i hope that helps.
How do you hook up two VCRs to a projector?
Only if your projector has two inputs,hook up the output video/audio of VCR into the input video/audio of the projector.
Radio Shack sells switchers to do this very function.
Coarse mixture has substances that are mixed and yet can still be seen. In other words, the mixed substances did not dissolve.
What is the lifetime of printed circuit board?
Depends on the material it's constructed from, the application for which it's being used and the atmospherics to which it's exposed. I have printed circuit boards from the very first model of an RCA transistor radio made in 1957 and the circuit board as well as the electronics still work.
Difference between alkalized and galvanized batteries?
The old galvanic power cells that we used in our flashlights, and so forth, actually had a thin wrap of zinc alloy as one of the two electrodes. The other electrode was composed of thin sheet material with an acid paste applied to it and wrapped round and round with the zinc.
(Plating something with zinc to make it rust-proof is called "galvanizing", which has nothing to do with your question, other than to explain where the term comes from)
Alkaline power cells use an alkaline or basic 'paste' rather than an acid one, in a structure that is much more delicate than the glavanix cells, but with much more surface area, to create a much longer-lasting cell.
(PS, they are not batteries until 2 or more power cells are connected. It's like a battery of psychological tests, a battery of heavy naval guns, or the old baseball term, 'battery', which meant the pitcher and catcher working together as a team.
