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…..
