Ohm My Goodness

Electricity, Electromagnetism, and Electricity

QuestionAnswer
Electricity kinetic energy. Caused by motion of electrons
Electrons Small negatively charged particles that surround atoms
Static Discharge When electrons jump from one object to another- felt by a shock
Static Electricity The build up of electric charge
Electric Charge When electrons move. Object that gains becomes negatively charged, object that loses becomes positively charged
Law of Conservation of Charge A charge can be transferred but not created or destroyed
Current The flow of charged particles (measured in amps) (A)
Resistance A materials opposition to flow of electricity (measured in ohms)
Conductor An object that allows electricity to flow through due to its low resistance
Insulator An object that does not allow electricity to flow through due to its high resistance
Switch A device that turns current on or off by opening or closing the circuit
Fuse Small piece of metal that melts if too hot. Breaks the circuit. Must be replaced
Series Circuit 1 loop for electricity to flow through. If any part of the circuit becomes disconnected, it becomes an open circuit and current stops.
Parallel Circuit 2 or more branches for current to flow through.
Circuit Breaker Contains metallic switch which bends when hot, opening up the circuit. (can be reset)
Magnetic Force Force of attraction and repulsion to each other and certain objects
Voltage Force that pushes the electrons
Magnetic Field The invisible area of force surrounding a magnet extending out from the poles. Allows magnets to interact without touching
Atoms Smallest form of matter
Magnet An object that creates a magnetic field around it and attracts iron, nickel, and cobalt
Electromagnet A temporary magnet created by electric current flowing through a coil of wire wrapped around an iron core
Attract When two objects pull towards eachother (examples, N-S poles, or + and - charges)
Repel When two objects push away from each other (examples: like poles, or like charges)
Poles Like poles repel, opposite poles attract
Magnetic Domains Atoms within a magnet that are aligned by magnetic poles.

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.
