1. Document yourself creating some static electricity and post to blog. Use the triboelectric series to decide which materials to use to
Generate static
electricity.
I didn’t have the materials to create static electricity but
I do know that a common way to do it is by rubbing a balloon on your skin and
watching your hair stand up. It a good frictional way to get static electricity
this is also called triboelectiricity.
I also like to use the example of a static shock by way of
friction like on a rug and then touching another human’s skin or the doorknob.
2. Contrast the speed of an electron with the speed of electrical motion in one sentence.
The speed of an electron is that of less the 1% of the speed
of light but its still pretty fast, electrical motion moves relatively slow
like the slowness of water flow through a water hose.
3. Briefly explain the relationship between resistance and energy. Use an example from your house.
Resistance is what hinders the flow of current or electrical
energy. The load of the energy makes the light come on in my home and the
resistance helps to make sure the right amount of energy is being put out from
the energy source in order for my light to come on.
4. What is the difference in AC and DC current? Give and example of each from your daily life. If you get shocked,
AC is alternating current, the current is able to go
clockwise or counter clockwise. Example would be like the power lines connected
to your house so you can plug your appliance to the outlets. DC is direct
current; this currents direction all goes the same and its constant. A battery
would be an example of a direct current.
5. Determine the equivalent resistance of a 6.0 Ω and a 8.0 Ω resistor if …
a. … Connected in series.
6ohms + 8ohms = 14ohms
b. … connected in parallel.
1/6ohms + 1/8ohms = 3.4ohms
