Marconi invented the radio. He invented a successful system of radio telegraphy in 1896. In 1895, Marconi invented equipment that transmitted electrical signals through the air (part of telegraphy and radio transmission).

The current in the socket can not checked directly because the sockets are connected in parallel to the supplu and we can not measure current in parallel it is always measure in series so connect a lod to socket after that use ammeter in series to measure electric current.

Electricity is used in an extraordinarily broad variety of ways. It finds application in domestic and commercial settings, as well a strong use in the industrial facilities that support our lifestyles. We use electricity as meanings of gaining on-the-spot access to (electrical) energy that can be changed into mechanical energy by motors. We use electric motors in thousands and thousands of items from tools and machinery to appliances to entertainment equipment. We light the heck out of our world using electric power. It's a huge application.

Electricity is something many of us take for granted. It is "behnid the scenes" in propping up the infrastructure of modern society. We light areas we use. Heat and cool places where we work and live. We ship, store, vend and prepare food with electricity. We work and relax using technology that is electrically powered.

Imagine a world without electricity. Get a small notepad and log each event every day that involves something you did that required electricity. It could be either direct application like lighting a room or working on a computer, or indirect, like using something that was manufactured using electricity. Our lives are powered up either directly or indirectly by electricity. Grabbing a backpack and hiking off into the woods is about the only way to get away from it. Oh, and leave behind all the things that were manufactured using electricity. Like you pack. And your equipment and packaged food and water. And your clothing.

bustard technology lol im 11 and i still cant do it!!

The first portable CD players hit the market in the same year that CDs were launched. Among others, Sony had a portable player that came with a mains power adaptor and an optional battery pack for use away from a mains supply.

The price was in the region of $400 / £250 and was in excess of twice the price of a static player at the time.

Both linear ICs and nonlinear ICs has an output voltage which is dependent on the input voltage. However, the difference is that linear ICs produce an output voltage which increases or decreases at a "fixed rate" relative to the input voltage.

Nonlinear ICs do not do this. A voltage regulator may be considered nonlinear because as you increase the input voltage the output will climb at the same rate (just like linear ICs), however, once the input voltage reaches a particular level point, the output no longer increases as you increase the input. This is at the point where regulation begins. The nonlinear IC no longer changes its output at a fixed rate relative to the input.

Video screens when videotaped flicker because the refresh of the screen doesn't match the sampling of the camera. This is less of an issue with progressive displays and LCDs. It's mostly a problem with CRTs.

I actually wrote a blog post on this a while back - the focus was where the video game jobs were in North America. Not 100% accurate by any means, but it's a nice start: http://gamejobhunter.com/blog/?p=14

This depends on the application. It may be OK to do so, or it may result in problems. If this is an already designed circuit, and you have a 820u cap that has blown, I suggest replacing with a 1000u (in my experience, this is more common and readily available), AND i usually up the voltage rating on the cap.

Capacitors typically blow due to overvoltaging or reverse polarizing them. If they've blown before, it's likely you'll have similar problems again, which is why i go with bigger, and higher voltage rated. I hate reduing things repeatedly.

Jim is transferred. Jim is a term meaning elec. energy. Also Jim is more scientific.

There are mainly people behind this technology to have invented the IMAX. Some of the guys were namely William C. Shaw, Nicholas Mulders, Roman Kroiter and Graeme Ferguson. There were many efforts made to improve the impact of movies. The very first one was in 1929, when Fox developed the 70mm format called Fox Grandeur. After that, many efforts soon followed including the VistaVision in 1954 and the CinemaScope in 1953. The very first IMAX film was entitled "Tiger Child," which became part of Expo 70 that was held in Osaka, Japan.

Because it's an electronics device, there can be several reasons why it won't turn on. Could be the battery's reached the end of its useful life and will no longer accept a charge. Maybe the charger itself isn't working properly and can't charge the battery. Then if it's been in storage for awhile, could be that the internal lever switches or circuitry that detects the presence of the battery isn't working properly (that also depends on the storage conditions, age of the camera). Generally though, what's happened is that the battery has aged and dried out, thereby not being able to take or maintain a charge. Try a new battery, first and see what happens.

Robots are "made" much the same way any other machine is made.

First, decide what you want the robot to do.

Second, design the robot, including every bolt, wire, computer processor and sensor.

Third, evaluate the feasibility based on the materials required, labor required and costs.

Fourth, re-design to meet budget constraints and/or other requirements.

And ABSOLUTELY last, actually start putting it together as designed by the engineer(s).

The electric car was invented so the earth can stay alive and healthy, meaning we humans stay alive 'cause of all the healthy trees and plants.

Not long just long enough to eat away your oesophagus & intestines.

Somewhere between 2 to 24 hours depends on the acid strength.

electromagnetizm!!!!!!!!!!!!!!!!!!!!!

No it is not electromagnetism I think it is magnetic fields, North side being negative and South side being positive....

whatever!!!!!!!!!!! =!

The definition of what it is, is actually in your question. It's a receiver that operates in the radio frequency spectrum. Anything that has a transmitter is said to transmit in radio frequency or `RF`. The term radio is short for radiotelegraphy, which has become generic over the years.

Where does the radio frequency start? Technically, it' at 10,000 hz and higher. That's not to say that there's lower frequency transmitters (The U.S. Gov't uses 2 hz. to reach our submarines when they're under water, but that's more of an exception than the rule. The radio frequency spectrum can extend into the gigahertz range for things such as satellite communications, and as our technology advances, we could eventually see frequencies in the teraherts.

So a radio frequency receiver is anything that will receive a a frequency in the radio frequency range.

Hope this helps,

Erica Feldman never existed. Apologies for the 12 year late answer, but the misinformation is still commonly thought of as true, so to clarify: Madam C.J. Walker was who we call Erica Feldman, however a vandal on Wikipedia changed the names to fictitious people. Regardless, Lady Jennifer Bell Schofield should be credited for the actual invention of straightening irons in 1912.

A "Relaxation Oscillator" is an "R/C" oscillator, in which a Capacitor is charged from a DC (Direct Current) fixed voltage source, through a resistor.

Connected across this Capacitor is a "device" that, initially, does NOT conduct any current. But when the Voltage on the Capacitor reaches a certain value (depending upon the characteristics of the "device") the "device" will "break down" or "avalanche", or suddenly drastically decrease in resistance.

This causes the "device" to quickly start to discharge the Capacitor. However, when the Voltage across the Capacitor and its parallel connected "device' decreases with the discharge cycle, the "device" will suddenly return to its "non-conducting" state, and the Capacitor again begins to re-charge.

The Capacitor again reaches the "break down" voltage of the "device", and the process continues, thus effectively creating "oscillations".

One version of this circuit uses a simple Neon lamp (such as a NE-1) as the "device". Typically, the "break down" or "ignition" voltage of a neon lamp is around 70 volts. At this point, the gas in the lamp "ionizes", becoming highly conductive.

However, when this voltage drops (as the lamp discharges the Capacitor) to about 50-60 volts, the lamp "goes out" (the neon gas is no longer ionized or conducting), and the Capacitor again starts to charge through the resistor.

This form of the "Relaxation Oscillator" will not operate at high frequencies (such as Radio Frequencies), and was often used to just generate a "flashing light" (the Neon lamp).

With the advent of semiconductors, a device called the Unijunction Transistor (UJT) was developed. It contained three leads, the Emitter, Base 1, and Base 2.

The junction of the Resistor and Capacitor is connected to the Emitter, with the "bottom" of the Capacitor (and the negative side of the Voltage Source) connected to Base 1 Base 2 is connected to the positive side of the Voltage Source.

Again, when the voltage on the Capacitor reaches the "break down" level, the UJT's "resistance" between the Emitter and Base 1 drastically drops, discharging the capacitor. However, when the discharging current through the UJT drops below a certain level, it again develops a high resistance between its Base 1 and the Emitter, and re-charging of the Capacitor begins again.

UJT circuits can operate at higher frequencies than the Neon bulb circuit. Often a resistor is inserted between Base1 and the common or negative side of the voltage source, and the resulting discharge current produced voltage across this resistor is used to trigger other devices. Also, the voltage waveform across the Capacitor approaches a linear "sawtooth" waveform (depending on circuit component values), but not nearly as linear as other approaches.

"Devices" of this type are considered to have a "negative resistance" characteristic, which is another discussion in itself.

The majority of kids in the US have cell phones. Since the question was asked in 2008, costs of cell phones have dropped to point where price is not a barrier to owning them.

Many electronics have several components in common. The most common are capacitors, resistors, transformers, and batteries. Others electronic components include antennas, terminals, connectors, and switches.
