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?
