Reading Questions
1. Contrast the speed of an electron with the speed of electrical motion in one sentence.
The speed of an electron refers to how fast an electron moves around its nucleus, while the speed of electrical motion refers to how electrons move from one point to another, which can be found using current and resistance.
2. Briefly explain the relationship between resistance and energy. Use an example from your house.
Resistance limits the flow of energy. A cellphone charger has resistance in it that limits the amount of energy going to my phone.
3. What is the difference in AC and DC current? Give and example of each from your daily life.
AC current can change directions and has a frequency, while DC current is steady. Batteries use DC current; Outlets use AC current
4. 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.
~3.43 Ω
