# Electric Fields

### Electric Forces and Fields

TermDefinition
Charge An imbalance of electrons as compared to protons.
Conductors Material that transfers charge easily
Insulators Material that does not transfer charge easily.
Conduction The process of charging a neutral conductor by touching it with a charged conductor.
Electric Field A region in space around a charged object in which a stationary charged object experiences an electric force because of its charge.
Coulomb's Law The electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.
Potential Difference The difference between the potentials of two points in an electric field measured in volts.
Capacitance The ability of a conductor to store energy in the form of electrically separated charges.
Induction The process of charging a conductor by bringing it near another charged object and then grounding the conductor.
Polarization slight relative shift of positive and negative electric charge in opposite directions within an insulator, induced by an external electric field.
emf "electromotive force" or energy per unit charge supplied by a source of electric current.
Grounding The process of removing the excess charge on an object by means of the transfer of electrons between it and another object of substantial size.

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:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

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.
