QuestionAnswer
What allows electrons to move through it easily? Conductor
closed path through which electrons flow circuit
accumulation of electric charges on an object. static electricity
circuit with more than one path parallel circuit
tendency of a material to opppose electron flow resistance
what does not allow electricity to move through it easily? insulator
a push that causes charges to move voltage difference
surrounds electric charge and exerts force on other charges. electric field
rate at which electrical energy is changed to another energy form electric power
flow of electrons through a conductor electric current
circuit with only one path series
unit of electrical energy kilowatt power
current is equal to the voltage difference of a circuit divided by its resistance Ohm's law
metal rod that directs lightning to Earth lightning rod
device that detects electric charges electroscope
the symbol V stands for? volts
this can open and close a circuit switch
transferring charge by touching is charging by contact
units used to measure the rate of electron flow amperes
the unit of electric energy is the kilowatt- hour
what expresses in watts electrical power
a flashlight is an example of what dry cell
a car battery is an example of what wet cell
one thousand watts of power used in 60 minutes is 1 kilowatt-hour
current has only one loop to flow through in a series circuit
current is measeured in amperes
the tendency for a material to oppose the flow of electrons is called resistance
electric energy is equal to power x time
Ohm's law states that the current equals current x voltage diffrenece
a current has 2 or more branches in a parallel circuit

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
