|
|
|
Physics: Q: complete the sentence A neutral atom will become positively charged if it ________ electrons and will become negatively charged if it __________ electrons. |
A: lost, gained
|
|
|
Physics: Q: State the three laws of the electric charges |
A: - Similar charges repel - unlike charges attract - charged objects can attract neutral objects |
|
|
Physics:
Q: where do the negative electrons "shift" if a negative rod is brought near an electro scope? |
A: down into the leaves
|
|
|
Physics: Q: where do the ngative electrons "shift" is a positive rod is brought near an electro scope? |
A: up to meet the rod
|
|
|
Physics: Q: What is the difference between static electricity and current electricity? |
A: - Static electricity flows freely (wherever it wants) and is not a sufficient source of electricity to ex: power a tv - Current electricity follows a path (circuit) and is a good source of energy to power ex: your house |
|
|
Physics: Q: Describe insulator |
A: An insulator doesn't let (blocks) electrons flow through and static can often build up
|
|
|
Physics: Q: describe conductor |
A: A conductor allows electrons to flow easily
|
|
|

A: A load, a battery, a switch , and a wire
|
|
|
Physics: Q: What is the difference between a series circuit and a parallel circuit? |
