moving charges

8.2 - moving charges

TermDefinition
current definition the rate of flow of charge
movement of charge in metals delocalised electrons
potential difference of 0 charged particles move randomly, overall current = 0
potential difference not 0 charged particles move in the same direction, current is induced
metal ions location/movement ions vibrate in a fixed position in a lattice arrangement
movement of charge in liquids charged ions in the electrolyte
main forms of electrolytes molten ionic compounds or aqueous ionic solutions
positive terminal anode
negative terminal cathode
ways to increase current thicker wire (more electrons per second) higher potential difference (electrons have more energy) lower resistance (electrons have more energy) coiling of the wire
example of non-electron current nerve cells with the electric current moving between the sodium and potassium ions

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.
