7. The first commercial power plant in the world was established in 1882 in New York City, at Pearl Street Station.
8. Thomas Edison and Nikola Tesla were influential figures whose rivalry accelerated the development of electrical systems.
9. Direct current (DC), promoted by Edison, was ultimately challenged by Tesla’s alternating current (AC), which remains the prevailing power system today.
10. The term “electricity” originates from the Greek word “ēlektron,” meaning amber, due to its static properties.
Everyday Experiences
11. The electric bill is derived from measuring kilowatt-hours (kWh), a product of power consumption and time.
12. Most household outlets supply voltage in the range of 110-120 volts in North America, while Europe typically uses 220-240 volts.
13. Your coffee maker uses approximately 600 to 1,200 watts of electricity per use, depending on the model.
14. Energy vampires refer to devices that consume power even when not actively in use, collectively costing households billions every year.
15. Compact fluorescent lamps (CFLs) use about 75% less energy than traditional incandescent bulbs.
The Science of Electricity
16. Electrons, which have a negative charge, are the primary carriers of electricity in conductive materials.
17. Voltage is analogous to the pressure in a water hose, while current represents the flow of water.
18. A phenomenon known as electrical resistance occurs when a material opposes the flow of electric current, generating heat.
19. Superconductors are materials that exhibit no resistance when cooled to critical temperatures, enabling groundbreaking applications.
20. The phenomenon of electromagnetic induction, discovered by Michael Faraday, is fundamental to power generation.
Shocking Wonders
21. The human body can conduct enough electricity to power a small light bulb when connected correctly.
22. Electrical burns are a significant hazard; they can cause severe cellular damage even if visible injuries aren’t apparent.
23. Over 40 million lightning strikes occur globally every year, illustrating the dynamic nature of electrical phenomena.
24. The distinction between static electricity and current electricity lies in how charges move: static accumulates, while current flows.
25. Electricity can produce magnetic fields, which form the basic principle behind many electrical devices, including motors and generators.
Applications and Innovations
26. Electroporation is a technique where electric fields transiently permeabilize cell membranes, impacting drug delivery and gene therapy.
27. Electric vehicles (EVs) are gaining popularity as a sustainable alternative to fossil fuel-powered transport, utilizing advanced battery technology.
