Metal drawn out into a thin flexible thread
What is a wire?
Material of an incandescent bulb filament
What is tungsten?
Benjamin Franklin invented this to help prevent fires caused by lightning strikes.
What is the lightning rod?
A D battery
1.5 V
Ex. Sunlight, candle
Electricity flows in a loop from the power source (battery) through the appliance (such as a light bulb) back to the power source
What is a complete circuit?
The gas inside a fluorescent bulb
What is mercury gas?
Benjamin Franklin determined that lightning was a form of this electricity.
What is static electricity?
A car battery
12.6 v
An alternative for a washing machine
Ex. washing clothes by hand on a washboard
The flow of electricity (electric kinetic energy)
What is current?
A major by-product of an incandescent bulb besides light
What is heat?
If Benjamin Franklin had been struck by lightning, he would have suffered these possible symptoms (if he survived).
Weakness, irritability, depression, memory loss...
A regular electric socket
120 v
Alternative to an air-conditioner
Ex. a fan (not electric fan!)
The difference in charge between two points; electric potential energy
What is voltage?
A difference between a regular incandescent and halogen light bulb
The gas within the envelope; glass vs. quartz envelope; heat produced; length of time bulb lasts
The kite and key experiment pointed to the nature of electricity when this happened.
The hairs of the thread stood up and sparks went to the key.
A clothes dryer electric socket
220 v
Alternative for a watch
Ex. a sundial, hourglass
What is a short circuit?
When electricity flows from a power source without going through an appliance back to the power source; this causes the power source (battery) to heat up
Name three advantages to LED bulbs compared to incandescent, CFL, and halogen bulbs
Lasts about 15 years (no filament to burn out)
Very energy efficient (less heat produced, requires little in the way of power)
No toxic chemicals (such as mercury)
Thunder is...
The result of lightning superheating the air making the air molecules rapidly expand and then come back together forcefully creating the loud boom.
over 100,000,000 v
Alternative for a computer
