Circuit electricity

QuestionAnswer
Define power source Gives electrons energy (battery, generator)
Define load Device that uses the electricity to convert it (bulb converts to light, fan converts it to motion)
Define control devices Controls flow of electrons through a circuit, such as the on/off function (switch, fuse, circuit breaker)
Define conducting wire To connect all components, allowing the flow of electrons between them (wire)
Symbol and units of voltage? Symbol is V, units is voltage (V)
Symbol and units of current? Symbol is I, units is ampheres (A)
Symbol and unit of resistance? Symbol is R, unit is ohms (weird circle shape)
Define voltage The force/pressure that pushes electrons through a circuit.
Define current The rate of flow of electrons
Define resistance The force that slows the flow of electrons. Resistance increased if wire is longer, thinner, or certain materials.
What is Ohm’s Law? A principle in electronics that defines the relationship between voltage, current, + resistance. It states that the current flowing through a conductor is proportional to voltage across it, assuming the resistance stays the same. If one changes, all do

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.
