Electricity

QuestionAnswer
Diode Semiconductor device that controls the flow of electricity in one direction.
Transistor Component of a circuit that turns the flow of electricity on and off
Parallel Circuit An electric circuit with more than one path for electricity to flow. If one bulb goes out the others will remain lit.
Series Circuit An electric circuit with only one path for electricity to flow. If one bulb goes out all other bulbs will go out.
Open Circuit Electricity cannot flow. Power is off.
Closed Circuit Electricity can flow. Power is on.
Semiconductor Primarily silicon. A substance that can act as either a conductor or an insulator.
Conductor Allows the flow of heat and electricity. Made of metals. Sea water.
Insulator Resists the flow of heat and electricity. Made of Non Metals. Rubber, wood, plastic etc.
Resistor A device in a circuit that limits or regulates the flow of electricity.
Static Electricity The build up of electrical charge on the surface of an object caused by an imbalance of electrons.
Friction The buildup of electrical charge on insulating materials caused by rubbing them together
Induction The buildup of electrical charge on an object without direct contact. (Lightning)
Electromagnet A soft metal core made into a magnet by the passage of electric current through a coil surrounding it.
Electrons Negatively charged subatomic particles found outside of the nucleus of an atom on energy levels.
Protons Positively charged subatomic particles found inside the nucleus of an atom.
Neutrons Subatomic particles that live inside of the nucleus and have NO charge.
Current Electricity The flow of electricity in an electronic circuit.
Volts The pressure or force that drives electric charge (electrons) through a conducting loop, enabling electrical circuits to do work
Amps The rate of electrical current flow, representing the volume of electrons moving through a circuit.

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.
