you plug it into a usb port on a computer and it does its magic.
A logic gate is an electronic circuit?
A: It is and it can be as simple as a diode resistor or as complex as an IC. A gate is also a function and you cannot get one without the other.
Logic gates can also be implemented with several nonelectronic technologies, fluidics (a type of hydraulics) is one of these.
I dropped my Motorola C290 in the toilet. Now only the endpower key works?
Seek advice in a phone shop.
This is a regular occurrence.
Sometimes the phone can be salvaged, but not often.
DO NOT attempt to turn the phone on again until it is dried out
A varistor is a variable resistor. It changes value dependent on the current draw and operates by changing its value as the resistor's temperature changes. For instance, during turn-on of a device, the resistor heats up causing the resistor to change it's value, thereby limiting the inrush current to the device. Once the initial start-up current is reduced and the device is operating normally, the resistor cools down and changes value again.
What is the procedure for testing the circuit of UJT relaxation oscillator?
Depends on what you need to know about it. First off, I'd use an oscilloscope. If it's set up correctly and you know how to `count graticules' that's really all you'll need to learn almost everything about your oscillator. IT should show you the wave forms at certain connection points, voltages as well as giving you some indication of the frequency. And if you want to know the current draw, you should probably have some type of milliamp meter on hand, which can usually be found in most miltimeters.
How do wet cell batteries work?
Rechargeable wet lead acid batteries use lead plates, lead oxide plate on positive electrode and an electrolyte solution of dilute sulphuric acid. They store energy in chemical form and it is converted to electricity. When a load is connected between the positive and negative terminals a chemical reaction causes electricity to flow through the load. Lead oxide changes to lead sulphate in the chemical reaction using sulphuric acid that releases electricity. Increasing amount of lead sulphate and reduced amount of sulphuric acid lead to dropping of current flow and this show the battery is discharged. By applying an external current to the terminals, this chemical reaction is reversed during a process known as charging.

How do you attach hair trimmer on Phillips norelco cool skin electric razor?
Here are instructions from the Philips website. Please see related links at the bottom of the answer To Groom Sideburns and Moustache: Switch the razor off. Clean the razor and razor head assembly by running under hot water before installing Trimmer. Press the Razor Head Release Button located on front side of razor, directly under the shaving heads to remove head assembly from razor. Remove razor head assembly from razor. Tilt the Trimmer Slightly backwards. Fit the Trimmer onto the razor (you will hear a click).The Trimmer is now ready for use. Activate the Trimmer by pressing the on/off button once.

What are the characteristics of a common emitter amplifier?
There are a number of characteristics found in a common emitter amplifier. Not only are the parameters considered, but also their performance. Characteristics and performance are: voltage gain/ medium; current gain/ medium; power gain/ high; input / output phase relationship/ 180 degrees; input resistance/ medium; and output resistance/ medium.
Where do the batteries go in the remote?
There should be a slot in the back that opens up, often with a screwdriver. Put the batteries inside of there, and make sure that you have the correct size and that they are put in correctly with the + and - lining up.
There are many to choose from ranging in price from a few hundred to many thousands of dollars. You will have greater reliability and a better user interface with the more money you spend. Companies include RTI, Universal remote, Control 4, Crestron, Amx, Savant, Elan, HAI. Often you would need to replace components with ones that will talk to each other. For a fully integrated system it is best to work with a dedicated audio video company for the best results. Many good companies can be found through CEDIA (consumer electronics design and installation association)
What is the Advantages of 3 wire rtd over 2 wire rtd?
It is more accurate, a 4 wire is more accurate than 3 wire and 3 wire is more accurate than 2 wire.
What is Dr Ian Lyons religion?
i have no idea what his religion is but i think is religion is called Phony-ism, i have not been able to trace any sort of information about him as a doctor. He has a few mixtures of belief system such as yoga-ism mixed with bhudisism or some sort of eastern religion. He may be a lost Christian or he may even be a Christian by name only but not by practice. may be he can say what religion he is publically.
A Nuvi commonly refers to a Garmin Nuvi. A Garmin Nuvi is a personal navigation system equipped with GPS. It is commonly used for setting routes for driving.
What is the difference between an engineer and a contractor?
An engineer is usually someone who has a specific degree in engineering, such as a construction engineer, which works out the design and construction of a building, but also takes into consideration the strengths and weaknesses of the materials used, load bearing capacities, etc. There are engineers for every field of endeavor. I'e., electronics engineer, broadcast engineer, structural engineer, highway engineer, etc.
A contractor is usually the company that takes the requirements and design as set forth by the engineer and creates the end result, such as a building, bridge, highway.
More than one engineer or contractor can be involved in the completion of the project, as their disciplines and specialties are varied. The engineer or contractors hired to complete the project will usually have experience in a particular field of work that involves multiple disciplines.
Where was the elevator invented?
By Elisha Graves Otis in New York in 1857
Fun fact: The first elevator designed for a passenger was built in 1743 for King Louis XV at his palace in France. The one-person contraption went up only one floor, from the first to the second. Known as the "Flying Chair," it was on the outside of the building, and was entered by the king via his balcony. The mechanism consisted of a carefully balanced arrangement of weights and pulleys hanging inside a chimney. Men stationed inside the chimney then raised or lowered the Flying Chair at the king's command.
Is it possible to connect a TV tuner card to be used for CRT monitor to LCD monitor?
Yes. As long as the output is VGA. There is no difference in the standard between CRT and LCD.
The mathematical treatment of electronic structure developed by schrodinger is called?
Quantum Mechanics
What goods would you guess that the American colonies did not export to England?
The Colonists probably did not export food items to England. The food was necessary for the survival of the Colonists, so it was exchanged throughout the Colonies.
