Michael Faraday
|
1791-1867 -- English
- Discovered electromagnetic force; named it "magnetic field" - Experimented with creating electric currents using magnets |
|
|
Joseph Henry
|
1799-1878 -- American
1831 - He created a more powerful electromagnet by using a horeshoe-shaped insulated iron bar that held in the heat from the electric current running through the wire (better than William Sturgeon's) |
|
|
William Sturgeon
|
1783-1850 -- English
1825 - created the first practical electromagnet by using a bar of soft iron inside wire coil |

George Ohm
|
1787-1854
mid 1800's - Flow of current through wire depends on wire's resistance Ohm's Law: Pressure (volts) = current (amps) x resistance (ohms) 3 parts of a circuit: source (battery), load (electric device such as lamp), conductors (wires) |
|
|
Andre Ampere
|
1775-1836
1820's - Parallel wires - current same - attract Parallel wires - current opposite - repel |
|
|
Allessandro Volta
|
1745-1827
1790's - Animal electricity=chemical reaction; chemical A + chemical B = new substance Railing+hook+moisture (rain) -> jump 1800 - battery - copper + zinc + salt water -> electricity |
|
|
Luigi Galvani
|
1737-1798
1786 - Lightning -> electricity? Railing + metal hook + frog + lightning -> jump - animal electricity Galvanize - to shock with an electric current |
