2. Contrast the speed of an electron with the speed of electrical motion in one sentence.
An electron moves at 1 cm per second while the speed at which electrical motion is transmitted is the same as the speed of light 300,000 km per second.
3. Briefly explain the relationship between resistance and energy. Use an example from your house.
Resistance impedes energy from crossing, like a wall in your house.
4. What is the difference in AC and DC current? Give and example of each from your daily life. If you get shocked,
Direct current and alternating current, direct current is like a battery while alternating current is in your house and its current is always changing direction.
If you get shocked by one you feel a tingle the other a hard prick.
5. Determine the equivalent resistance of a 6.0 Ω and a 8.0 Ω resistor if …
a. … connected in series. 14 Ω
b. … connected in parallel 13.45 Ω
