9/16 Manga Electricity questions

  • DOCUMENT YOURSELF CREATING SOME STATIC ELECTRICITY AND POST TO BLOG. USE THE TRIBOELECTRIC SERIES TO DECIDE WHICH MATERIALS TO USE TO GENERATE STATIC ELECTRICITY.



  • CONTRAST THE SPEED OF AN ELECTRON WITH THE SPEED OF ELECTRICAL MOTION IN ONE SENTENCE.
The speed of an electron is very slow and electrical is 300,000 km per second which is equivalent to the speed of light.



  • BRIEFLY EXPLAIN THE RELATIONSHIP BETWEEN RESISTANCE AND ENERGY. USE AN EXAMPLE FROM YOUR HOUSE.
ANd example of electrical resistance could be a toaster oven. It uses electricity to create heat which is then converted into light by the load that keep a resistance on the amount of current flowing through. 



  • WHAT IS THE DIFFERENCE IN AC AND DC CURRENT? GIVE AND EXAMPLE OF EACH FROM YOUR DAILY LIFE. 

Ac is alternating current which mean the direction of the current alternates directions frequently. FOr instance, a wall outlet.

DC is direct current which means the direction of the current is constantly in the same direction. For instance, a 9v battery.

  • DETERMINE THE EQUIVALENT RESISTANCE OF A 6.0Ω AND A 8.0 Ω RESISTOR IF is it connected in series
6 = 8 = 14


  • "..." if connected parallel.
6 * 8 / 6 + 8 = 3.43
