Blog Your Way To a Successful Private Practice
What is a Blog?Blogs are a type of website often defined as an on line journal or diary. Although there are many blogs where the blog author keeps a log of their own thoughts, experiences and ideas, bloggers also frequently share and discuss information from other sources.Blogs typically focus on a certain topic and have frequent (sometimes daily) posts (or entries).

MLM Compensation
Making money in this industry depends on a few fundamental factors: the soundness of the company, the quality and the market of the products, and your own enthusiasm, commitment, and hard work.In every serious network marketing company, some people are making six-figure incomes, and lots are making little or nothing. The latter are often people who dabble in network marketing with the "I'll try

All capacitors have a certain amount of resistance to the passage of AC current. ESR (Equivalent Series Resistance) is the sum of all internal resistances of a capacitor measured in Ohms. An ideal capacitor has ZERO ohms ESR. From the diagram below you can see a resistor in series with a “PERFECT CAPACITOR”. The value of the resistor is called ESR. Electrolytic Capacitors have a tendency to increase its ESR overtime due to drying or corrosion. High ESR is a frequent problem in today’s electronic circuit. Even a 1 or 2 ohms rise in ESR can cause complicated problems. Under normal conditions the ESR has a very low value, which stays that way for many years unless the rubber seal is defective, in which case the electrolyte’s water component gradually dries out and the ESR creeps up with time. The increase in ESR increases both voltage drops within the capacitor and the heat, produced in the capacitors due to resistive heating. If you don’t check for ESR, you may be in for a “TOUGH DOG” repair. High ESR is the first sign of a capacitor failure. High ESR will cause complete circuit failure, over heating of capacitor, loading of the circuit, overstressing of other circuit components and other undesirable effects.

Why should I use an ESR?

Because measuring an electrolytic capacitor with an analog or digital capacitance meter can MISLEAD a technician into believing that a defective capacitor is good. This can waste your precious time and you are unable to repair the equipment. Which means you can’t charge your customer! If you don’t test for ESR on the capacitor, you will always miss the bad capacitor. Normally, these bad capacitors hav

Debt Management Plans - How They Can Help You Get Out Of Debt
Debt management plans (DMP) consolidate your short term debts into one monthly payment. They also negotiate lower interest rates, enabling you to pay off your accounts usually in less than five years. Before you sign up with one of these companies, you want to investigate them to be sure they are legitimate.Services OfferedA DMP company, also called debt consolidation, handles the acco

How to Exhibit Your Company
IntroductionExhibitions are one of the best ways to put your company and products in front of your customers and prospects in order to obtain good quality leads. They are also one of the most expensive forms of marketing and can easily over run their budget.

RFID Tags Read for 69 Feet
We now have RFID Tags that can be read from 69 feet, not just any RFID Tags or using just any system, no this system and these tags were designed by Hackers at the annual Defcon Conference in Las Vegas Nevada. No matter who designed it, it works and one of the biggest problems with RFID in the passive type tags was range. Having a system, which can read them from afar or thru containers means additional se

The No.1 Biggest Cause of Failure
I will confess that for me personally my biggest arch enemy is procrastination. I’m a sucker for it, for me getting ideas or initial enthusiasm is the easy part, it’s keeping up the momentum and following my idea through to completion that’s the hard part. My mind will find an infinite number of things that I can do before I go ahead and follow my plan through. Even writing and submitting

itance meter can MISLEAD a technician into believing that a defective capacitor is good. This can waste your precious time and you are unable to repair the equipment. Which means you can’t charge your customer! If you don’t test for ESR on the capacitor, you will always miss the bad capacitor. Normally, these bad capacitors have high ESR reading which your normal multimeter or digital capacitance meter can’t measure. Only by using the ESR meter, you will be able to measure the ESR on the capacitor and you will not be fooled by capacitors with bad ESR. ESR meter can even work IN-CIRCUIT, which means you don’t have to solder out the capacitor in order to measure it using normal capacitor tester, which would not be accurate anyway.

Do you know that ESR meters can perform other wonders besides checking the ESR of a capacitor? Some digital ESR meter have the features of checking:

» Low ohms resistor such as 0.22 ohm, 0.33 ohm and etc.

» Horizontal yoke coil winding of a picture tube, inductor and primary winding of a transformer – If a shorted turn is present, the inductance drops dramatically and the meter will show the ohms reading.

» Horizontal output transistor (HOT) in a monitor or TV – If an open-circuit reading is obtained, the short-circuit is elsewhere. If the short-circuit remains, the transistor is faulty.

» Short-circuit in the track, usually trace to the components - You can use the ESR meter to locate short-circuits on printed circuit boards by measuring the actual track resistance. If the reading increases as you probe further along the track, you know you’re going in the wrong direction!
