The Lead Acid Battery
Lead-acid batteries, invented in 1859 by French physicist Gaston Planté, are the oldest type of rechargeable battery. Despite having a very low energy-to-weight ratio and a low energy-to-volume ratio, their ability to supply high surge currents means that the cells maintain a relatively large power-to-weight ratio. These features, along with their low cost, make them attractive for use in motor vehicles to provide the high current required by automobile starter motors.

This inverter is very easy to construct, reliable, and even powerful enough to light up a 15W florescent tube (if you cool your transistor well). The only hard-to-find piece of this baby is the so-called yellow inverter transformer. It's a miniature high frequency transformer that has a 25mm x 20mm x 5mm ferrite core, 30 turns of primary, 15 turns of feedback, and 250 turns of secondary all concentric, wound on plastic frame than wrapped with a 'yellow' adhesive tape. If you can't find it in your local electronic shops then ....etc

BlackBerry maker RIM Co-CEO Jim Balsillie in the company after the release of the third quarter took a JPMorgan analyst Hall Rod interview. He said in an interview, RIM in some areas far ahead in Apple, especially upcoming entry next tablet.

Hall interview questions are basically revolves around how RIM compete with Apple and Google. Leslie Barr said: Entries are latecomers, Apple and Google coach purses will (tied house) in the digital home integration direction.

He noted that introduction has been identified in the Tablet PC. The pro ....etc

ABSTRACT
This project has been a great learning experience for me; at the same time it gave me enough scope to implement my analytical ability. This project as a whole can be divided into two parts:
The first part gives an insight about the footwear and its various aspects. It is purely based on whatever I learned at Sarup Tanneries. One can have a brief knowledge about footwear and all its basics through the project. Other than t ....etc

There are 3 leads in a transistor viz. collector,emitter and base. When a transistor is to be connected in a circuit,it is necessary to know which terminal is which.
There are three systems in general from which we can determine which terminal is which,they are as follows

1. When the leads of the transistor are in same plane and unevenly spaced then they are identified by the position and spacing of leads. The central lead is the base lead.the collector lead is identified b ....etc
