Electricity 1-3

Topics 1-3 in Electricity

TermDefinition
Electricity Flow of charged particles
Parts of an atom Proton, neutron, electron
Static electricity Build up or imbalance of electric charges within or on the surface of a material.
Current electricity Steady flow of charged particles
Electrical discharge gaining or losing an electrical charge to achieve balance with objects around it
Grounding connect object to earth to drain excess electrons
Ionizing Uses ions (positive or negative atoms) to neutralize objects
Neutral charge equal positive and negative charge
Positive charge more protons than electrons
Negative charge more electrons than protons
Law of charges: Opposite charges attract
Law of charges: Similar charges Repel
Law of charges: neutral and charged attract
Cell one positive and one negative terminal. 1.5V
battery multiple positive and negative terminals linked together
Resistors slows the flow of electrons
lamp load that converts electrical energy to heat and light
load converts electrical energy to other types of energy
motor converts electrical energy to mechanical (movement) energy
wire conductor that allows electrons to flow
series circuit one pathway for electrons to flow
parallel circuit multiple pathways (called branches) for electrons to flow
Potential difference another name for voltage
voltage the "pressure" or "power" that electrons carry
current the amount of electrons moving through a conductor
ohms law R= V/ I
Ampmeter used to measure current
voltmeter used to measure voltage
ohms used to measure resistance
open circuit metal contact is broken. Electricity will not flow
closed circuit Metal to metal contact is intact and electricity will flow
Resistance of good conductors Low resistance
Resistance of insulators high resistance
Water tank= what in a circuit? battery- similar to what in a water system?
Water wheel= what in a circuit? load- similar to what in a water system?
Water pipe= what in a circuit? conductor- similar to what in a water system?
Current symbol I
Voltage symbol V
Resistance symbol R

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.
