QuestionAnswer
Law of Electric Charge like Charges repel and opposite charges attract
Electric Force Force between charged objects
Electric Field a region around a charged particle that can exert a force on another charged particle
3 Ways to “charge it” Friction, Conduction, Induction
Conservation of Charge no charges are created or destroyed
How can a charge be detected using an electroscope
Conductor material in which charges can move easily,
Ex of Conductor copper, silver, aluminum, mercury
Insulator Material that charges can’t move easily
Ex of Insulators plastic, rubber, glass, wood
Static Electricity Buildup of electric charges on an object
Electric discharge loss of static electricity as charges move off an object
Lightning one of the greatest examples of electric discharge
Lightning Rods Pointed Rod connected to the ground through a wire
Grounded objects in contact with the earth
Dangerous places to be In a lightning storm Beaches, Golf courses
21. Cell device that produces an electric current by converting chemical energy into electrical energy
22. Battery device made of many several cells does the same thing
23. Parts of a battery – electrolyte & electrode Electrolyte= mixture of chemicals that turns chemical energy into electrical energy, Electrode=two conducting metals that make contact with the electrolyte, charges enter or exit
24. Types of Battery Cells wet cells and dry cells
25. What is the relationship between potential difference & volts volts is used to express potential difference
26. Photocells & examples part of a solar panel that converts light into electricity, calculator
27. Thermocouple device used to convert thermal energy into electrical energy
28. Drawing of thermocouple
Section 3 & 4
29. Electrical current p. 433 the rate at which charges pass a given point
30. Two types of electrical current AC and DC
31. Direct Current & diagram direct current has one direction
32. Alternating Current & diagram alternating current continually changes direction
33. Voltage the difference in energy per unit charges as a charge moves between two points in the path of a current
34. Resistance the opposition to the flow of electric charge
35. What is the relationship between resistance & current resistance can determine the speed of a current
36. How thickness, length & temperature effect electrical current thick wires have less resistance, long wires have more, the colder the wire the less resistance
37. What is Ohm’s Law? current, voltage and resistance could be expressed with the equation I=V/R.
38. Electrical Power Formula Power=Voltage X Current
39. Watt the unit of electricity
40. How is household energy measured by the energy company by multiplying the power in kilowatts by the time in hours
41.
41.Circuit a complete, closed path through which electric charges flow
42.Load a device that uses electrical energy to do work
43. What do ALL loads do ? offer some resistance to electric currents and cause the electrical energy to change into other forms of energy such as light energy or kinetic energy
44. Explain the relationship that a switch plays in “opening” or “closing” a circuit by turning the switch down then you complete the circuit and by lifting it up, opening the circuit not allowing electricity to travel
45.Series circuit circuit in which all parts are connected in a single loop.
46. How many paths are in a series circuit one
47. Draw an example of a series circuit in your notebook
48. Explain what happens if one load in the series circuit is malfunctioning all loads following it will not function
49. Parallel circuit circuit in which different loads are located on separate branches.
50. Why is this circuit important in the wiring of the lights in a building if one bulb stops working the rest of the lights will still receive electricity.
51. Explain what happens if one load in the circuit is malfunctioning the other loads will continue to function.
52. Give an example of a parallel circuit in your house wiring from my TV, computer, and lights
53. Using the last paragraph p. 444 and fig. 26, explain the causes and dangers of overloading a circuit overloading a circuit could result in a fire due to increased heat from outlets.
54. Explain how a fuse and circuit breakers help with circuit safety in your house and automobile fuses prevent electricity to flow if the flow is too high, circuit breakers automatically open the circuit if current is too high.

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.
