It stands for CeNtRa Science Corp. A Taiwan based company established in 1992, with three factories located in Taiwan and mainland China. They have become the largest MOV manufacturer in both Taiwan and China.

CeNtRa Science Corp. is a leading manufacturer and exporter of power protection equipments, specializing in manufacturing metal oxide varistors.

Auto switching usually refers to the input voltage being automatically selected, therefore one on a laptop probably means you can use multiple charger units with it or it selects its own mains charger voltage.

Quartz vibrates when a voltage is applied between opposite faces of a crystal.

The frequency of the vibration depends on the thickness of the crystal, and on

the direction of the faces compared to the natural planes in the crystal structure.

If you're referring to Roman numerals, CV = 105.

You must learn to yell very loud, which is extremely effective especially for children. This is considered by most to be a better alternative than intercom systems as a method of communication.

The positive lead is marked with a red dot or a + symbol.

Resistors, capacitors, inductors, diodes are all passive components.

The Werker label on SLI batteries is sold at Batteries Plus and made by East Penn.

That is NOT correct! Werker is a Batteries Plus privately owned brand name. Werker labeled batteries can be made by anyone that Batteries Plus has entered into a private label agreement with. When going to their store it is likely that their Werker batteries are made by 12 plus people. In the SLI automotive batteries they use Exide as their primary, they do have an agreement with East Penn as well and several other Mexican battery manufacturers. Problem with a Batteries Plus is you don't know what you're buying but it is likely you are buying whatever they could get the cheapest the day they needed batteries.

The manufacturer of the Batteries Plus branded SLI battery depends on where the store is located. My local store orders directly from Exide Batteries Corp. and East Penn. Corp. From my past experiences working for an auto parts store East Penn has one of the best automotive offerings on all batteries while Exide has a lot less. I sold East Penn for years and was very familiar with their products and how they worked. Also keep in mind most Battery Plus stores are franchises not corporately owned.

Electronics built on current technology typically works best at low temperatures. For certain applications, very low temperatures (even as low as 0K) are ideal, as conductivity increases and approaches superconductivity at this temperature.

Superconductivity means no loss of energy in heat, and allows for certain electronic devices to operate much more efficiently and potentially faster than at higher temperatures.

However, today's practical electronics are not designed for operation at very low temperature. Some electronic components, such as some forms of resistors or capacitors will fail at low temperatures. Other components, including the solder, wires, the circuit board and all mechanical parts including connectors would become fragile, brittle, or otherwise struggle.

Today's electronics are normally rated for operation in a 0..70C temperature range (commercial grade), -40..+85C (industrial grade) and -55..+125 (military grade).

For a rule of thumb and for today's practical electronics, "room temperature" is a good operating temperature regardless of theoretical advantages of superconductivity.

The Riddex pest repeller produces high-frequency sound waves that are harmless to humans and pets (except rodents), but which are heard by insects and rodents and are supposed to drive them away. This may sound good in theory, but it doesn't work in practice. At best, electronic pest repellers may work for a few hours or days, but they apparently have no long-term effect on pests. Also, many people claim that they can hear a whining and/or buzzing noise made by the repellers. After numerous complaints, the company that produces Riddex agreed with the FTC to not make certain claims as to their product's effectiveness. You can read the agreement on the FTC site: http://www.ftc.gov/opa/2003/07/global.shtm

It stands for watt-hour. In relationship to batteries, it measures how many watts in an hour a battery can sustain. A 63 watt-hour battery will supply 63 watts for 1 hour, or 6.3 watts for 10 hours or 31.5 watts for 2 hours, etc. It is extremely difficult to determine, from this number, how long your equipment (say, a laptop) will run using a 63 hour battery. The thing for which this number is most useful is battery comparison. A 20 WHr battery will last twice as long as a 10 WHr battery and half as long as a 40 WHr battery and so on.

A properly operating CD player will not damage a CD because there is no physical contact with the disc except in the center, where no music is stored, however a defective player can damage the disc if the alignment is off causing the disc to touch the internal components of the player.

Yes from over current from power surges, over driving by the user in case of amplifiers, or other component failure around the transistor. Also overheating can cause transistor failure from poor ventilation or loos heatsink.
