Physics

Grade 11: Electricity and Magnetism

TermDefinition
Coulomb's law The magnitude of the electrostatic force exerted by one point charge (Q1) on another point charge (Q2) is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance (r) between them.
Electric field A region of space in which an electric charge experiences a force.
Electric field at a point The electric field at a point is the electrostatic force experienced per unit positive charge placed at that point.
Ohm's law The potential difference across a conductor is directly proportional to the current in the conductor at constant temperature.
Power The rate at which work is done.
EMF The maximum energy provided by a battery per unit charge passing through it.
Faraday's law of electromagnetic induction The magnitude of the induced emf across the ends of a conductor is directly proportional to the rate of change in the magnetic flux linkage with the conductor.

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.
