Luigi Galvani‚ an Italian physician and physicist is credited with starting bioelectricity. He was born in Bologna‚ Italy on September 9‚ 1737. He never expected to study science and instead wanted to focus on theology. His family encouraged him to pursue otherwise and in 1755‚ following his father’s desires he entered the University of Bologna‚ the Faculty of Medicine and Literature. In the 1770’s‚ Galvani became interested in studying the anatomy of frogs and electrophysiology. In the 1780’s‚ he

It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.[11] The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead‚ it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter. "Uno" means one in

only in living tissues. A few years later‚ in 1800 Alessandro Volta discovered that electricity could be produced through inorganic means. In fact‚ by using small sheets of copper and zinc and cloth spacers soaked in an acid solution‚ he built a battery - the first apparatus capable of producing electricity. Naysayers were quick to predict that electricity would never serve a useful purpose. Obviously they were very wrong. Electricity has a central role in our lives and to this day Electrochemistry

(c) (d) Figure 9.17‚ shows simple apparatus that determines the relative conductivities of pure water and solutions. Two metal electrodes are connected to a battery and a light bulb. When the electrodes are immersed in the solution‚ the light bulb will glow only if circuit is complete so that electricity flows from one electrode to the other through the solution. The more ions a solutions has‚ the greater conductivity

In a simple series circuit a battery is connected through an ammeter to an electric lamp. A voltmeter is connected parallel to the lamp. The ammeter reads 0.75 A and the voltmeter 50 V. What is the resistance of the lamp neglecting the current drawn by the voltmeter? If the current in

This crime cannot be battery as no force has been used‚ neither can it be GBH or ABH as no wounding or injury has been caused.

elements electron configuration is 11 which is quite low when comparing them to the other elements in the periodic table. However this metal is more reactive than lithium which is a good thing because it is quite strong. This element has three main energy levels and the outer shell only has one election and this is higher than lithium however potassium is stronger. This is known as a soft metal and is a solid‚ it can react in acids but is a very slow reactant. This is placed in group 1 of the periodic
