What is Electricity?
- Electricity is ubiquitous; it powers our daily lives.
- Household electricity is typically a 240-volt sinusoidal waveform.
- Electric shock is a hazard; avoid direct contact. (Optional viewing suggestion: https://www.youtube.com/watch?v=oB1v-wh7EGU)
The Electricity System
- Consists of supply, transmission & distribution, consumption, control, power electronics, and the marketplace. (additional information at https://happeningthemovie.com/)
A Brief History of Electricity
- Early understanding involved observations of natural phenomena like magnetic stones (compasses), electric fish, and lightning.
- Static electricity was studied in the 17th and 18th centuries. The Leyden jar allowed for the storage of static electricity.
- Ewald Georg von Kleist invented the capacitor.
Galvani and Volta
- Luigi Galvani's experiments with frog legs led him to believe animals produced electricity.
- Alessandro Volta disagreed, creating the first battery (using silver, zinc, and saltwater-soaked paper strips).
The Relationship Between Electricity and Magnetism (1820)
- Hans Christian Ørsted demonstrated a link between electricity and magnetism. His experiment showed that a compass needle is deflected near a current-carrying conductor.
- André-Marie Ampère showed that parallel current-carrying conductors attract or repel depending on current direction. He formulated mathematical descriptions combining electricity and magnetism.
Charles Coulomb (1736-1806)
- Described the electrostatic force between charged particles (Coulomb's law): F = kQ1Q2/r^2.
- Developed a torsion balance to measure weak electrical and magnetic forces.
- Defined the law of magnetic repulsion and attraction. The coulomb (unit of electrical charge) is named after him.
Benjamin Franklin
- Demonstrated that lightning is electricity.
- Invented the lightning rod.
Joseph Henry (1797-1878)
- Major American electricity researcher.
- Made many electromagnetism inventions including self-inductance, an electric doorbell, and an electric motor.
Finnish Hydropower
- Finland has over 220 hydropower plants with a combined power output of approximately 3100 MW. A table with specific plant details is included.
