Explanations: answer key for all 10 questions

Q1: In which year did Thomas Edison demonstrate a long-lasting carbon filament bulb?
Answer: 1879
His team tested thousands of materials before settling on carbonized bamboo.
Q2: Which British inventor lit his home with incandescent bulbs before Edison?
Answer: Joseph Swan
Edison and Swan later formed a joint company in Britain.
Q3: Who demonstrated an early arc lamp around 1809?
Answer: Humphry Davy
Arc lamps were bright but harsh.
Q4: Which inventor improved carbon filaments and worked with Edison?
Answer: Lewis Latimer
He also drafted patent drawings for Bell's telephone.
Q5: Which metal replaced carbon in bulb filaments?
Answer: Tungsten
Tungsten has a very high melting point.
Q6: Who introduced neon lighting in Paris in 1910?
Answer: Georges Claude
Neon glows red-orange; other gases make other colors.
Q7: Which London theatre was the first public building lit entirely by electricity?
Answer: The Savoy
It opened in 1881 with Swan's lamps.
Q8: Why have LEDs replaced incandescent bulbs?
Answer: They use far less energy
LEDs can last 25 times longer.
Q9: The 2014 Nobel Prize in Physics honored the invention of which LED?
Answer: Blue LED
Blue LEDs made white LED light possible.
Q10: Fluorescent lamps glow because of what coating?
Answer: Phosphor
UV light makes the phosphor glow.

Electric Light Trivia Quiz – Lighting Up the World

Before electric light, people relied on candles, oil lamps and gas. In the 1800s, inventors raced to create safe, long-lasting electric lights. Arc lamps lit streets, and Joseph Swan and Thomas Edison developed practical incandescent bulbs.

Edison's success came with a whole system: power stations, wiring and meters. His Pearl Street Station in New York began supplying electricity in 1882, and cities soon glowed at night.

Lighting kept improving. Tungsten filaments, neon signs, fluorescent tubes and finally LEDs made light brighter, cheaper and more efficient. Today LEDs use a fraction of the energy of old bulbs and last for many years.
