Electrical Principles& Technologies- topics 1 & 2

secondary cells rechargeable cells
batteries made up of two or more cells
electorchemistry the study of chemical reactions involving electricity
electrolysis breakdown using electricity
electroplating coating a cheaper metal with the atoms of a more expensive metal, using an electrolyte
electrolyte liquid or paste used to conduct electricity
electrode conductor through which electric current enters or leaves a device or material
ion atom that has become electrically charged because it has lost or gained electrons
superconductor perfect conductor; substance with no resistance to electron flow
resistor device having resistance to electron flow; often used to control current in a circuit
rheostat continuously variable resistor used to regulate electric current; variable resistor
Ohm's law as long as temp. remains constant, the resistance of a conductor remains constant. And, current is directly proportional to voltage applied.
series circuit circuit-one pathway for the current, so the same current passes through all the components
parallel circuit circuit- the current can flow in two or more paths
photoconductors a resistor that becomes more conductive when exposed to light
transistors device(usually with 3 layers). Small VOLTAGE in middle layer controls CURRENT between outer layers-can act as a SWITCH or AMPLIFIER
integrated circuits circuits made of inseparable/microscopic components-(formed on a piece or chip of semiconductor crystal)

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.
