Unlock the Power of Galvanic and Voltaic Cells

A common galvanic cell consists of two different metals immersed in separate beakers containing their respective metal ions in solution. These metals are connected by a salt bridge or separated by a porous membrane.

A galvanic cell, also known as a voltaic cell, is an electrochemical cell that generates an electric current from spontaneous oxidation-reduction reactions.

Luigi Galvani and Alessandro Volta were scientists who contributed to the development of galvanic cells. Galvani discovered animal electricity, while Volta invented the voltaic pile, the first electrical battery.

<p>In common usage, the word 'battery' is used to refer to a single galvanic cell. However, a battery properly consists of multiple cells.</p> Signup and view all the answers

<p>In 1780, Luigi Galvani discovered that when two different metals are in contact and then both are touched at the same time to two different parts of a muscle of a frog leg, the frog's leg contracts. He called this phenomenon 'animal electricity'.</p> Signup and view all the answers
