Electric Circuits

QuestionAnswer
Electric circuit When electricity is produced by a source of current, does work, and returns to its source. Contains source of current, a conductor, and a load
Ampere Represents the passage of 1 coulomb in one second
Amperage The amount of electron current. A typical lightbulb uses between 1 and 1.5 amperes of current
Voltage Used to measure electrical "pressure"
Watt Used to measure electrical power
E = P x T Energy = Power x Time
Voltmeter Measures voltage
Ammeter Measures amperage
Galvanometer Simplest electric meter. Used for measuring very small electron currents
Multitester Combines the capabilities of several of these simple instruments
Resistance The characteristic of a material that hinders electron flow through it. Good conductors have low resistance, poor conductors have high resistance
Ohm The unit used for measuring resistance
Ohmmeter Device used to measure resistance. Most multitesters include this function
Georg Ohm Discovered relationship between voltage, current, and resistance
Ohm's law States that voltage equals current (in amperes) times resistance (in ohms).
Series circuit Loads are arranged in a series and the electric current flows through each load one after another
Parallel circuit Loads are arranged in separate branches of the circuit and the current is divided among them
Overloaded circuit Occurs when too many appliances and electrical devices are connected to a circuit at one time, forcing the wires of the circuit to carry more current than they can handle
Short circuit The touching wires create a "short cut" for the electrons to flow directly from one wire to the other, avoiding the load
Fuses and circuit breakers Devices that guard against overloads and short circuits

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.
