Unit 3

Electricity and Magnetism

TermDefinition
Electric Charge A property that leads to electromagnetic interactions between the particles that make up matter
Static Electricty The buildup of electric charge on an object
Electrical Conductor A material through which charges can move freely(Many are metals)
Electrical Insulator A material through which charges can not move easily(Plastic, rubber, glass, and dry air are examples)
Semiconductor A special class of materials that conduct electric charge better than electrical insulators but not as well as electric conductors(Their properties allow them to be used to control the flow of charge)
Electric Current The rate of flow of electric charges
Voltage The amount of work required to move each unit of charge between two points(Expressed in volts(V))
Resistance The opposition to the flow of electric charge
Electric Curcuits A complete, closed circuit in which electric charges can flow
Series Circuit A circuit in which all parts are connected in a row that forms one path for the electric charges to follow
Parallel Circuit A circuit in which electric charges have more than one path that they can follow
Magnetic Pole The ends of magnets
Magnetic Force A push or a pull created when you bring two magnets together
Magnetic Field The area surrounding a magnet where magnetic forces can be detected
Magnet Any material that attracts iron or objects made of iron
Electromagnetism When electric currents and magnetic fields interact with each other
Electromagnet A solenoid around an iron core that combines the magnetic field of the solenoid with the magnetic field of the magnetized iron core

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.
