TermDefinition
Amperes Unit for measuring electric current; very small currents are measured in milliamperes
Circuit Diagrams A drawing using symbols to represent the different components of a circuit
Current Electricity The continuous flow of charge in a complete circuit
Electric Circuit A complete pathway that allows electrons to flow
Electric Current The amount of charge passing a point in a conductor every second
Electric Load Any device that transforms electrical energy into other forms of energy, such as light bulb, buzzer, heater, and motor
Electric Potential Energy Electric energy stored in a battery
Electrical Resistance The ratio of voltage to current
Electrochemical Cell Electrodes in electrolytes that convert chemical energy into electrical energy stored in charges; also called batteries
Electrodes Two terminals in a battery or other electricity source; usually made of two different metals but can be a metal and another material
Electrolyte Substance that conducts an electric current. In a dry cell, the electrolyte is a moist paste; in a wet cell, the electrolyte is a fluid
Energy The ability to do work
Ohm The unit of measurement for electrical resistance
Ohm's Law The mathematical relationship comparing voltage (v), current (I), and resistance (R), written as R=V/I
Potential Difference The amount of electric potential energy per one coulomb of charge at one point in a circuit compared to the potential energy per coulomb of charge at another point in the circuit; also called Voltage
Resistance The property of any material that slows down the flow of electrons and converts electrical energy into other forms of energy
Resistor An electrical component with a set amount of resistance that slows down current and transforms electrical energy into other forms of energy
Volt The unit of potential difference
Voltage The amount of electric potential energy per one coulomb of charge at one point in a circuit compared to the potential energy per coulomb of charge at another point in the circuit

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.
