Electricity

TermDefinition
Current The number of electrons flowing in a circuit
Amperes Unit for current
1 Amp 1 Coulomb/second
Voltage or Potential Difference Electrical potential energy per coulomb of charge
Resistance When electrons flow with some opposition
Resistors Device the reduces or controls the flow of electricity
Ohm's Law Current = Voltage / Resistance
Ohms Units of resistance
Volts Units of electric potential
DC, Direct Current The charge flows in one direction only like in batteries
AC, Alternating Current Electrons in the circuit move in one direction, then switch and then flow in the opposite direction, wall outlets
Adapters A device that converts AC into DC or vice versa
Diodes Allow electrons to flow in one direction only. They help change AC into DC
Electrical Power The work done per unit of unit
Watt Unit of Electrical Power
Power Power = Current x Voltage (P = IV
Series Circuits Arranging components in a electrical circuit that creates one large continuous loop with the components
Parallel Circuit A circuit in which each component is connected separately in its own "loop"
Fuse/Circuit Breakers Devices designed to prevent too much current and causing a fire
Multimeter A device that measures voltage, current and resistance digitally or an analog reading
Ammeter A meter that only measures current

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.
