2. Contrast the speed of an electron with the speed of electrical motion in one sentence.
The speed of eletrons through a conductor is usually fast whereas the speed of electrical motion like current is typically slow.
3. Briefly explain the relationship between resistance and energy. Use an example from your house.
The more resistance something has, the less energy it outputs as the energy is typically lost in heat. For example my iMac requires more energy to run than does my razor and the iMac usually gets much hotter as that energy is lost through heat.
4. What is the difference in AC and DC current? Give and example of each from your daily life. If you get shocked,
AC = alternating current vs. DC = direct current. My cell phone uses direct current where as the lights in my house as well as the outlets use alternating current. You're probably more likely to be shocked by dirct current.
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) = 3.428 ohms
