### physics ch. 34 vocab

potential difference the difference in electric potential between two points free charge flows when there is a difference and will continue until both points reach a common potential
electric current the flow of electric charge measured in amperes
ampere SI unit of electric current. a flow of one coulumb of charge per second is one ampere. symbol A
voltage source a device such as a battery or generator , that provides a potential difference
electric resistance the resistance of a material to the flow of electric current through it is measured in ohms
superconductivity- a property of a material that has infinite conductivity at very low temperatures , so that charge flows through it without resistance
ohm the SI unit of electric resistance . one ohm is the resistance of a device that draws a current of one ampere when a volt is impressed across it
ohm's law the statement that the current in a circuit is direclty portional to the voltage impressed across the circuit , is inversely proptional to the resistance of the circuit
direct curent (DC) electric current whose flow of charge is always in one direction
alternating current (AC) electric current that repeatedly reverses direction twice each cycle . usually at 60 cycles per second of hertz
electric power the rate at which electrical enegery is converted into another form such as light, heat, or mechanical energy

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:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

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.
