CPO Electricty terms

QuestionAnswer
Alternating Current An electric current that travels to the load and then changes direction to travel back to the generator.
Amp The basic unit of electric current. Equal to 1 coulomb per second
Battery A group of chemical cells connected together to generate direct current electricity.
Chemical Cell A device made of an electrolyte and two electrodes that makes direct current electricity
Circuit A circle of electricity usually consisting of a power source, a wire, a switch, and an electrical device.
Conductor A material that electricity flows through easily.
Coulomb A unit of electrical charge. Equal to 6.24 billion billion (lots of ) electrons.
Current The flow of electricity. Measured in amperes (amps)
Direct Current An electric current that travels in only one direction
Distance A amount of length, usually measured in meters
Electricity The energy of electrons flowing through a conductor
Electric Force The force that causes electrons to move or flow in a conductor
Electron A negatively charged particle found in atoms
Hertz 1 time (cycle) per second
Insulator A material that electricity does not flow through easily.
Joule a unit of energy or work
Kilowatt hour1 A unit of power. Equal to 1000 watts.
Kilowatt hour2 A unit of electric energy used by power companies.
Kinetic Energy Energy that is actively doing work
Magnetic Force The attraction or repulsion between the poles of magnets
Magnetic Field A region of space around a magnet in which magnetic forces are noticeable.
Meter a unit of distance
Newton A unit of force
Parallel Circuit A circuit where electricity passes through more than one pathway at the same time.
Potential Difference The difference in the charge between two points in a circuit.
Potential Energy Stored energy that can do work in the future
Power The rate at which work is done (how fast work gets done).
Proton A positively charged particle found in atoms
Resistance The opposition to the flow of current in a circuit.
Series Circuit A circuit where electricity passes through only one pathway.
Static Electricity Electricity where the charge is not moving. When Charge builds up and moves once.
Volts A unit ofthe pushing force of electricity. Also called the potential difference or electromotive force.
Watt A unit of power. 746 watts equal 1 horsepower
Work The result of using a force to move and object over a distance (Force * Distance)
Parallel A ciruit that allows on bulb to stay lit even if the other bulb is removed.
Series A ciruit where a bulb will NOT stay lit if the other bulb is removed.
AC Alternating Current
DC Direct Current
Ohm A unit of Resistance (to the movement of electrons)
Ohm's Law decribes the connections between current,voltage, and resistance.

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.
