TermDefinition
electric charge a fundamental property that leads to the electromagnetic interactions among the particles that make up matter
static electricity electric charge at rest; generally produced by friction or induction
electrical conductor a material in which charges cannot move freely
electrical insulator a material in which charges cannot move freely
semiconductor an element or compound that conducts electric current better than an insulator does but not as well as a conductor does
electric current the rate at which electric charges pass a given point
voltage the amount of work to move a unit electric charge between two points; expressed in volts
resistance in physical science, the opposition presented to the current by material or device
electric circuit a set of electrical components connect such that they provide one or more complete paths for the movement of charges
series circuit a circuit in which the parts are joined one after another such that the current in each part is the same
parallel circuit a circuit in which the parts are joined in branches such as that the voltage across each part is the same
magnet any material that attracts iron or materials containing iron
magnetic force the force of attraction or repulsion generated by moving or spinning electric charges
magnetic pole one of two points, such as the ends of a magnet, that have opposing magnetic qualities

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.
