Questions from Manga

2. Contrast the speed of an electron with the speed of electrical motion in one sentence.
The electrons that flow through a current are moving fast, yet the electric current is actually a slow flow.
3. Briefly explain the relationship between resistance and energy. Use an example from your house.

The power supply of a particular object makes the current flow while resistors hinder this flow. Some appliances use electric resistance. Appliances that heat up use resistance to do so. As the energy flows through the resistors they "hold" onto the energy and thus the metal will get hot as the resistance grows higher and the friction of the electrons grows higher.
4. What is the difference in AC and DC current? Give and example of each from your daily life. If you get shocked, 
DC current is also called direct current is when the direction and the size of the current is fixed. A DC power supply is a battery. AC or Alternating Current is when the current flow is alternating cyclically with time. An example of this is a wall outlet.
5. Determine the equivalent resistance of a 6.0 Ω and a 8.0 Ω resistor if …
a. … connected in series.
6.0 + 8.0 = 14.0 ohms
b. … connected in parallel.
(6.0 x 8.0) / (6.0 + 8.0) = 3.43 ohms
