Topic - Physics for my Child - 6 FULL SENTENCES REQUIRED - Use Words and TYPED ONLY

Instructions: USE the Physics concept of the phenomenin of electric charge to answer the following: (6 SENTENCES MINIMUM)

Through the magic of time travel, you find yourself sitting around the table with Thales of Miletus (from 600 BC), Charles François du Fay (from 1733), and Benjamin Franklin (from 1748). You all have a babble fish in your ear that translates any language.

Thales was one of the first to report the phenomenon of electric charge. He found that rubbing amber with fur made it attract hairs and tiny bits of straw:

a) Charles du Fay - 2 SENTENCES MINIMUM

Charles du Fay proposed two ‘electrical fluids’, resinous fluid (from rubbing amber with fur) and
vitreous fluid (from rubbing glass with silk). (1) Have Charles du Fay explain to Thales the properties of
the two ‘fluids’.

b) Ben Franklin - 2 SENTENCES MINIMUM

Ben Franklin proposed a single ‘electrical fluid’ to replace du Fay’s two fluids but still explain the
same phenomona. Have Franklin explain to du Fay how his single fluid model is (1) different, (2)
better, and (3) how the Law of Conservation of Charge works based on his model.

c) Electrical Fluid - 2 SENTENCES MINIMUM

Finally, based on modern knowledge, you know what the ‘electrical fluid’ actually is. (1) Explain to Franklin what
the fluid is and (2) how his model was wrong.

Explanation / Answer

a) Charles du fay :

According to charles du fay, There are two states of electrification, Vitreous and Resinous. Bodies electrified (charged) with vitreous electricity attract bodies electrified with resinous electricity and repel other bodies electrified with vitreous electricity.

b) Ben Franklin :

According to Ben Franklin, there is just one form of electrical fluid. His theory called for a neutral equilibrium of electrical fluid, with electricity flowing from an area of electrical excess to areas lacking the electrical "fluid". Franklin deemed the areas of excess "positive" - a flipped viewpoint from our current scientific understanding wherein electron rich areas likely hold an overall negative charge or a negative dipole.

c) Electric fluid is nothing but charge, and franklin's mopdel was wrong in the senmse that it did not segregate between the -ve and +ve charges
