QuestionAnswer
the accumulation of excess electric charge on an object static electricity
charge the can be transferred from object to object, but it cannot be created or destroyed law of conservation of charge
a material in which electrons are able to move easily conductor
a material in which electrons are not able to move easily insulator
the process of transferring charge by touching or rubbing charging by contact
the rearrangement of electrons on a neutral object caused by a nearby charged object charging by induction
the net movement of electric charges in a single direction electric current
is related to the force that causes electric charges to flow voltage difference
a closed path that electric current follows circuit
the tendency for a material to oppose the flow of electrons, changing electrical energy into thermal energy and light resistance
the current in a circuit equals the voltage difference divided by the resistance Ohm's law
the current has only one loop to flow through series circuit
contain two or more branches for current to move through parallel circuit
the rate at which electrical energy is converted to another form of energy electrical power

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.
