Stack #123168

QuestionAnswer
Michael Faraday The inventor of the electrical generator and the electrical transformer
Like charges repel one-another the first rule of electrical charge
Opposite charges attract one another the second rule of electrical charge
All electrical charges attract or repel one another, depending on whether they have opposite charges or similar charges principle #1 of the force that exists between electrical charges
The force between charged objects is directly proportional to the amount of electrical charge on each object principle #2 of the force that exists between electrical charges
The force between charged objects is inversely proportional to the square of the distance between the two objects principle #3 of the force that exists between electrical charges
Photons small "packages" of light that act just like small particles
Charging by induction Charging an object by forcing some of the charges to leave the object
Charging by conduction Charging an object by allowing it to come into cntact with an object that already has an electrical charge
Electrical current The amount of charge that travels through an electrical circuit each second
Conventional current current that flows from the positive side of a battery to the negative side. This is the way current is drawn in circuit diagrams, even though it is wrong
Resistance A measure of how much a metal impedes the flow of electrons
Open circuit A circuit that does not have a complete connection between the two sides of a battery. As a result, current does not flow
Series circuit When electrical devices are hooked up in a circuit that makes it so that if one part of the device fails, all of it will
North Pole magnet One side of a magnet that is attracted to the South Pole side of a magnet
South Pole magnet One side of a magnet that is attracted to the North Pole side of a magnet
Magnetic field lines Lines that indicate the direction that the magnetic force pushes at any point near the magnet
parallel circuit a circuit that is hooked up in such a way to allow devices to function independently of one another. If one stops working, the others can still work
monopole a magnetic pole isolated by itself. Scientists are looking for this.
dipoles magnets which have a north pole and a south pole. So far, all magnets found have been dipoles

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.
