Summary
- An Electric Field can be visualized by plotting the paths of a hypothetical positive-charged particle placed in the vicinity of one or more charged objects.
- The electric field strength is E = kQ/d^2. The units are Newtons.
- Volts is potential-energy per Coulomb: V = J/C. A 1-Volt potential stands ready to do 1-Joule of work on a 1-Coulomb particle, moving it against an electric field.
- Capacitors store electric energy in the form of an internal electric field.
- A capacitor blocks direct current, but passes alternating current. The higher the frequency, the more current passes through a capacitor. This is the opposite effect of a coil. More on that in Ch. 22.

Ch. 19 Review Questions
Complete the following problems starting on p. 444: #31, 32, 33abc, 34, 35, 36abcde, 37, 38, 39, 40, 41, and 42abcd.
Write these up neatly IN YOUR OWN HANDWRITING. A.I. answers are not acceptable. Please keep the same numbering or I won't be able to grade it. Show all your calculations clearly and box-in the final answer so I can find it.
Make sure you work all 21 questions, worth 21 points.
