QuestionAnswer
amperes a unit of electric current equal to a flow of one coulomb per second
circuit diagrams a diagram of a circuit
current electricity dynamic electricity a flow of electric charge
electric circuit an electrical device that provides a path for electrical current to flow
electric current a flow of electricity through a conductor;
electric load the circuit connected to this terminal is the load
electric potential difference Voltage, electrical potential difference, electric tension or electric pressure is the electric potential difference between two points, or the difference in electric potential energy of a unit charge transported between two points
electrical resistance electric resistance: a material's opposition to the flow of electric current; measured in ohms
electrochemical cells An electrochemical cell is a device capable of either deriving electrical energy from chemical reactions
electrodes a conductor through which electricity enters or leaves an object, substance, or region
electrolyte a liquid or gel that contains ions and can be decomposed by electrolysis, e.g., that present in a battery
energy the strength and vitality required for sustained physical activity
ohm the unit used to measure resistance
Ohm's law electric current is directly proportional to voltage and inversely proportional to resistance; I = E/R
potential difference the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
resistance the ability not to be affected by something
resistor a device having a designed resistance to the passage of an electric current.
volt the SI unit of electromotive force, the difference of potential that would drive one ampere of current against one ohm resistance.
voltage an electromotive force or potential difference expressed in volts

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.
