This is what a positively charged
object will do to another positively charged object.
What is
“repel”?
This is how the charges of an
electron and proton compare.
What are “equal and opposite”?
These two things determine the
strength of the force between two
charged objects.
What are “the size of the charges and the distance between
them”?
This is a diagram of an object that has been polarized.
What is - - - - - -
+ + + + + +
This type of charging involves two object the
come in contact and end up with opposite
charges.
What is “charging by
friction”?
T
This is what charging by non-contact is
called.
What is “charging by induction”?
Charge does not flow freely through these
materials.
What are “insulators”?
This type of charging occurs between
objects that come in physical contact and then both have the
same charge.
What is “charging by
contact”?
These materials share properties of both conductors and
insulators.
What are “metalloids”?
This is a diagram the demonstrates how two
uncharged Electrophorus devices can be charged by induction with a positively charged Electrophorus.
What is + - + + + - - +
This is where all electricity wants to
flow.
T
What is “the ground”?
These are the units of potential difference.
What are “volts”?
This type of device converts kinetic
energy to electrical energy.
What is a “generator”?
This type of current is more practical for smaller electronic
devices.
What is “direct current (DC)”?
This is the relationship between current and
resistance for a circuit.
What is an “inverse relationship”?
All magnets must have two of these.
What are “poles”?
This is the region around a magnet
where its effects may be felt.
What is the “magnetic field”?
This is the type of magnet that has domains that
align and un-align in the presence of an external
magnetic field.
What is a “temporary magnet”?
These are two ways to strengthen an electromagnet.
What are “increasing the number of current carrying
coils and increase the current traveling through
the coils”?
This is the field line pattern created when the
unlike poles of two different bar magnets are
brought near but not in contact with each other.
What is
This device converts chemical energy into
electrical energy.
What is a “battery or a cell”?
This is the relationship between potential
difference and current for a circuit.
What is a “direct relationship”?
This is a diagram of two bulbs connected in series to a battery.
What is
This device is made of a conductor attached to an insulator. The insulator
serves as a handle so that you can pick up the device
without touching the conductor. This device is
called ...
What is “an electrophorus”?
This was the name given to naturally
occurring magnetic stones that were
used for early navigation.
What are “leadstones or lodestones”?
Daily Double!
This type of device converts kinetic
energy to electrical energy.
What is a “generator”?
Final Jeopardy
The electrical company
charges $0.25 for every
kilowatt-hour of electricity your
household uses. This is the
monthly cost of your 300 watt
hairdryer, if it is used on
average, 20 hours a month.
What is $1.50?
