Key Objectives:Key Objectives:
Identify the necessary vocabulary terms to better understand how electricity is created in a wet cell and a dry cell battery
Key TermsKey Terms
Electrode ElectrolyteVoltagePotential DifferenceChemical Cell (Wet and Dry)
Electrode
The metal or carbon element that reacts with an acid or base electrolyte that produces voltage
Electrolyte
A substance usually a liquid acid or base that reacts with electrodes to create voltage
Voltage
The electric potential energy per unit charge.
Measured in Volts
Potential Difference
The amount of energy per unit charge needed to move a charged particle from a reference point to a designated point in a static electric field; voltage.
Chemical Cell (Wet and Dry)
Chemical cells are batteries
Parts of a Battery (Wet Cell)
Parts of a Battery (Dry Cell)
Chemical Wet Cell
Wet cells are batteries that require a strong acid or base solution to react with the carbon and metal electrodes to create voltage
Chemical (Dry) Cell
A dry cell uses a dry paste electrolyte to react with the metal and carbon electrodes to produce electricity.

A Special Scientist
Count Alessandro Giuseppe Antonio Anastasio Volta – b February 18 ,1745 – d. March 5. 1827
Alessandro Giuseppe Volta
An Italian physicist known especially for the invention of the battery in 1800.
Birth
Volta was born in Como, a town in present-day northern Italy (near the Swiss border) on February 18, 1745
Life
In 1774, he became a professor of physics at the Royal School in Como.
A year later, he improved and popularized the electrophorus, a device that produced static electricity.
Contributions to Science
His promotion of it was so extensive that he is often credited with its invention, even though a machine operating on the same principle was described in 1762 by the Swedish experimenter
Contributions to Science
He discovered methane after reading a paper by Benjamin Franklin of America on "flammable air."
Contributions to Science
Volta searched for it carefully in Italy and in November, 1776, he found methane at Lake Maggiore.
By 1778 he managed to isolate methane
Contributions to Science
He invented the voltaic pile, an early electric battery, which produced a steady electric current
Death
Volta retired in 1819 to his estate in frazione of Como, Italy, now named "Camnago Volta" in his honor. He died there on March 5, 1827
Honors
The word “Volt” a measurement of potential difference and the word “Voltage” come from his name
Modern day honors go to him for being the father of the electric automobile.
Honors
Toyota furnished the electric hybrid engine to Italian design house Giugiaro to build the Toyota Volta in 2003.
Honors
Later on Chevrolet, in 2011, was only able to use the name "Volt" to honor one of the world's most ingenious inventors
Controversy
Some scholars argue the Baghdad battery could be the first chemical battery. Iranians were using it as electroplating tool.
You Decide…..
