QuestionAnswer
the accumulation of excess electric charge on an object. static electricity
states that charge can be transferred from one object to another but cannot be created .or destroyed. law of conservation of charge
material,such as copper wire, in which electrons can move easily. conductor
material in which heat flows slowly. insulator
process of transferring charge between objects by touching or rubbing. charging by contact
process of rearranging electrons on a neutral object by bringing a charged object close to it. charging by induction
the net movement of electric charges in a single direction,measured in amperes. electric current
related to the force that causes electric charges to flow:measured in volts. voltage difference
closed conducting loop through which an electric current can flow. circuit
tendency for a material to oppose electron flow and change electrical energy into thermal energy and light;measured in ohms resistance
states that the current in a circuit equals the voltage difference divide by the resistance. ohm's law
circuit in which electric current has only one path to flow. series circuit
circuit in which electric current has more that one path to follow. parallel curcuit

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.
