when electricity was discovered. In June 1752 Benjamin Franklin proved that lightening is electricity. In 1791 Galvani publisged his doscoverey of Bio electricity. In 1800 Volta invented the Galvanic cell‚ in which this day in age we call it the battery. Without these advances we woukd be living in a society without any sort of electrity. In July 2012 more than 700 million people in India had been left without power in the world’s worst blackout of recent times. This lead to fears that

is possible to get electricity from a lemon (and a few other acidic fruits and vegetables) using two strips of metal. The most readily available combination is copper and zinc. The zinc piece can be taken from the casing of an old carbon "D" cell (battery); some zinc coated nails may work as well. The copper can be a coin containing a high amount of copper. (Note: some recent copper coins‚ including the newer U.S. pennies‚ contain low amounts of copper mixed with zinc. If in doubt‚ use a pure copper

Sensitive LPG Leakage Alarm This project is an ultra-sensitive LPG sensor that generates loud beeps when it senses any gas leakage. It detects vapours of liquefied petroleum gas anywhere between 200 and 10‚000 ppm and drives a pies buzzer to catch attention for immediate action. The buzzer beeps until the concentration of gas in the air decreases to a safe level. The circuit uses an MQ6 gas sensor‚ which is designed to sense LPG‚ propane and isobutene gases.
