Electronics

To make things simpler!

Imagine if they had to draw an actual transistor or battery everytime... that would have been both time consuming and difficult for the person studying the diagram ( as one engineer's drawing of a transistor may be totally different from others )

Non electronic methods of communication are ways of communicating through non-electronic sources such as letters, reports, memorandums, etc. Before the invention of electricity, Communication was slow and difficult. Some messages took days, weeks and even months to arrive to its destination. It was also not as affective and less people were able to receive these messages at once.

The chemistry of the battery. Everything chemical has a certain electric potential. The battery voltage is the difference between these two potentials. The classical chemicals for batteries was carbon and zinc, which produce 1.5 V. Rechargables, which are based on nickel and cadmium or nickel and hydrogen, produce 1.2 V. The lead acid cells in your car battery, on the other hand, produce 2 V, and some lithium chemistries produce 3 V.

Yes you can. However, the 2025 is 0.5mm thinner so will be a slack fit. It is also down on capacity; a lowly 165mAh as opposed to the meaty 220mAh of the 2032. The real difference is that on a constant 15Kohm load drawing 190uA @ 200C, the CR2032 will last 1000 hours and the CR2025 800 hours.

Compared to paper records, utilizing an Electronic Medical Record (EMR) system is a rapid and efficient method to preserve critical medical information. The art and science of medicine is practiced within a very information driven environment and most of the information in a clinical setting is based on patient records and related information. Many clinical information systems were designed as financial systems - then incorporated detailed clinical patient information as a second thought. This did not create well integrated patient oriented information systems.

Paper records are bulky and take up costly space. Filing, retrieval of files and the refiling of paper records are very labor intensive methods with which to store patient information. Plus if a record is checked out for one department another department can't access the chart. The impact of not having immediate access to key information in emergency situations can be serious. Paper medical charts also cannot be effectively searched and used to track, analyze and/or chart voluminous clinical medical information and processes. They cannot be easily copied or saved off site. Physician's orders and the corresponding results (labs, etc.) can also be issued, saved and maintained much more efficiently in a comprehensive EMR system.

One explanation I was given was that when a letter was needed to represent current in formulas, C had already been used, and it was decided to use the next unused letter of the alphabet, which was I. However, I prefer the other explanation, which is that in the early days of investigations into electricity, what we now call current was called Intensity, hence the letter I. It should never be confused with Impedence, the symbol for which is Z.

Rub Hughstun Homans nipples on it

What is Hughstun Homans nipples? You need to show picture of this what it is describe what it looks like how it works and helps. WHat kind container it comes in? What Im looking for is answer on cell phone restoring inside screen display that phone does still work but I cant see my screen its black. I need to recover my contacts and pictures very badly it wasnt dropped in water or broke on glass. I slammed it down on coffee table by accident dropped it couple times now its not working its black and I cant see no text menu or contacts I need to know how to recover my screen display to work. How do you do that? Its prepaid att go phone. Has time still on it and works I can make calls and receive them on front little screen I can still get date time and caller id number of calls or text.Just cant push no buttons for menu. I never saved or stored numbers to sim card just in my address book and contact list. Never stored or used internet wap browser.Just made received calls text voice mail. Most of ATT business ph #'s work close to my home. THey dont give u answer on internet to recover to talk to staff about it or online.HELP I have till Dec 13,2012 to retrieve. I have taken out my sim car and battery waited charged up batter and put it in another att go phone it originally was in. THat still dont help. Since I didnt save info or contacts on sim card I probably wont get no info out of sim card correct. ATT said they automatically back up contacts on cell phones. No answer there.>? Help How do I recover my contacts Now I just stuck it in freezer left it longer 5 min still cold front little screen works not inside still no data. Now I cant dial out on it. THank answer Dont always believe what you read. NO phone at all now.

You have to remove the fake wings on the back. It took a lot more force to remove the fake wings on the back then expected, but it did pop off. The two AA batteries are located inside his back underneath the fake wing jet pack. Replace the batteries and then snap the fake wing pack back on.

1. Turn the soldering iron on.
2. Clean the surfaces to be soldered. Any tarnish will make a bad joint.
3. Put the two things you want to solder together.
4. When the iron is ready, place it on where you want to join the two

   objects.

5. Slightly tilt the side if the point of the iron up, enough for the solder to fit in, and feed the solder in.
6. Keep hold of the two objects until the solder is cool, otherwise the will just come apart.

The Piezo-Electric effect is when an electrical voltage induces a movement in certain solid crystals, ceramics, bone, etc. It also is the reverse effect, where movement or strain of that material induces an electrical voltage.

The small piezo disc in the back of your alarm watch is one example, generating a tone from an AC signal. Another example of the reverse effect is the starter on your gas grill, generating thousands of volts from the snap action of the impact from the trigger hammer.

Hook up the jumper cables in this order: (1,2,3,4) (1) One end of positive cable to positive post of GOOD battery (2) Opposite end of positive cable to positive post of DEAD/LOW battery of disabled vehicle (3) One end of negative cable to negative post of GOOD battery (4) Opposite end of negative cable to GROUND on disabled vehicle (a good ground is preferred over the negative post, however, the cable can also be hooked to the the battery post). To remove the jumper cables after starting, reverse the order (4,3,2,1)

Because screw terminals would be far too bulky. Imagine a CPU measuring 1.5" by 1.5", with 300 connections, all of them screw terminals. Your laptop would be the size of a filing cabinet.

The basic electrical components are :-
Battery
Resistor
Capacitor
Inductor
Transformer

Transistor Applications

Transistors have a multitude of applications, among which are:

Amplification of all kinds ( radio , television , instrumentation )

Signal generation (oscillators, wave generators , radio frequency emission)

Switching, acting switches (relay control, supplies power switched, control lamps, modulation pulse width PWM)

Detection of light radiation (phototransistors)

Junction transistors (one of the most basic types) have 3 terminals called Base, Collector and Emitter , which depending on the encapsulation of the transistor can be distributed in various ways.

Transistor Encapsulation

Now we are going to see the transistors from the outside. They are encapsulated in different shapes and sizes, depending on the function they are going to perform. There are several standard packages and each package has a terminal assignment that can be found in a general catalog of transistors.

Regardless of the capsule they have, all transistors have their data printed on their body , that is, the reference that indicates the transistor model . For example, the transistors shown on the right have the reference "MC 140".

TO-3 capsule . It is used for high- power transistors , which always have an aluminum radiator that helps dissipate the power generated in it.On the top left we see its distribution of terminals, noting that the collector is the chassis of the transistor. Note that the other terminals are not the same distance from the two holes.

On the right we see how to place it on a radiator, with its screws and the insulating mica. The function of mica is that of an electrical insulator and at the same time a thermal conductor.

TO-220 capsule . It is used for transistors of less power, for voltage regulators in power supplies and for low power thyristors and triacs. Generally they need an aluminum radiator, although sometimes it is not necessary, if the power they are going to dissipate is low.

Below we see how to place the radiator and the fixing screw. An insulating mica is usually placed between the transistor and the radiator, as well as a plastic spacer for the screw, since the metal part is connected to the central terminal and sometimes it does not interest that it comes into electrical contact with the radiator.

TO-126 capsule . It is used in low power transistors, which generally do not need a radiator. At the top left we see the terminal assignment of a BJT transistor and a Thyristor. Below we see two transistors that have this capsule placed on small aluminum radiators and fixed with their corresponding screw.

TO-92 capsule . It is widely used in small signal transistors. In the center we see the terminal assignments in some models of transistors, seen from below. Below we see two such transistors mounted on a printed circuit board. Note the indication "TR5" on the silkscreen , which indicates that transistor number 5 of the circuit is mounted in that place, according to the electronic diagram.

TO-18 capsule . It is used in small signal transistors. Its body is formed by a metal casing that has a protrusion that indicates the terminal of the Emitter

Miniature capsule . It is used in small signal transistors. Like the previous one, they are quite small in size.

Clippers are diode, wave-shaping circuits. The output of clipping circuits looks like a portion of the input signal is clipped off, kind of like a limiter. A clipping circuit requires at least two basic components, a simple diode and a resistor. The output wave form can be clipped at different levels by interchanging the position of the diode and or resistor, and changing the voltage of the dc battery.
