Vocabulary Chapter 18

TermDefinition
Ampere(A) The Si unit of electric current, defined as one coulomb of charge passing a point in one second: 1 A=1 C/s
Cross Section A view of a solid made by cutting it perpendicular to its longest axis.
Current The amount of electric charge flowing past a specific point in a circuit for a unit of time.
Electric Current The flowing of electric charge, measured as the rate at which electric charge flows past a given point. > The SI unit of current is ampere, A; 1 ampere=1 coulomb per second (1A=1C/s).
Ohm (Ω) The SI derived unit of resistance. > One ohm=1 volt per ampere(1Ω=1 V/A).
Ohm's Law At a constant temperature, the current in a metallic conductor is directly proportional to the potential difference between its ends and inversely proportional to its resistance: V=IR >ohm's law does not hold for semiconductors.
Resistance Opposition to current flow offered by a conductor semiconductor; the ratio between potential difference across and current in a conductor: R=V/I >1Ω=1 V/A
Resistivity A quantitative indication of the electrical resistance of material at a specific temperature.
Resistor A device that offers resistance in an electrical circuit. The symbol for a resistor is; ~~~
Electric Power The time-rate at which electric energy is expanded. >Electric power is a scalar quantity.
Volt(V) The SI unit of electrical potential or potential difference.
Watt(W) The SI unit of power; a derived unit equivalent to one joule per second: 1W=1 J/s.

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.
