100
draw a simple electric circuit with a light that can be turned on or off
circuit
100
purpose of copper wire in a circuit
conduct electricity
100
What kind of charge does an
object have if there are more
negative particles than positive?
negative
100
potential energy
energy that is stored for future use
100
Type of electricity in our home (AC or DC)
AC
100
What is problem with burning circuit boards?
lots of toxic chemicals which include lead (and if using styrofoam to burn then styrene which is a known carcinogen)
200
Provides energy to move charges through a circuit
electric cell
200
how many paths does a series circuit have
one
200
How will two objects act
if they both have a positive
charge?
they will repel each other
200
kinetic energy
energy that is in motion
200
material that electric current can pass through easily
conductor
200
Where does the most electronic waste come from?
Ist world countries such as US and Europe
300
material that electrons cannot easily pass through
insulator
300
How many paths does a parallel circuit have?
2 or more
300
Type of electricity that causes
static electricity
300
amperes (amps)
the units to measure current
300
what is e-waste and give 3 examples
waste generated from electronic waste which includes cell phones, tvs, printers, screens, laptops, etc
300
What financial reasons does the US have in order to ship e-waste to China?
shipping containers from China arrive and usually would go back empty so they make it really affordable to ship their e-waste
400
Draw an electric circuit that can be turned on and off that involves 2 light bulbs in series
series circuit
400
What would happen in a parallel circuit if one socket was empty?
The other bulbs would light up
400
How many volts come out of a socket?
120V
400

400
charge that stays on an object
static charge
400
What two things are not allowed to stay in Hong Kong for recycling?
Cathode ray tubes and batteries
500
in a series circuit with 10 light bulbs if one of the light bulbs burns out the circuit will....
not work because the flow of electrons is broken
500
What kind of circuits do homes have?
parallel
500
Why don't birds get shocked on a power line?
they don't make a complete circuit
500
kWh
kilowatt hrs or how much power (energy) and object uses
500
What is a lumen?
a unit of measure to indicate how bright an object is, where 1 lumen is the amount of light given off by one candle
500
What countries receive electronic waste?
Developing countries such as China and Ghana.
