RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

Here is the "Electricity - Basic Navy Training Courses" (NAVPERS 10622) in its entirety. It should provide one of the Internet's best resources for people seeking a basic electricity course - complete with examples worked out. See copyright. See Table of Contents.

**CHAPTER 9 QUIZ**

**PARALLEL CIRCUITS**

1. Work out the answers for each unknown in the practice circuits in the following drawing.

2. Four motors are paralleled on a 120 volt line. What is the total line current if each

motor draws 2.5 amperes?

3. What is the total resistance of one 10 ohm resistor, one 20 ohm resistor, and one

30 ohm resistor if they are connected in parallel?

4. Two loads are connected in parallel on a 220 volt line. The first draws 25 amperes and

the second draws 41 amperes. What is the total current? What is the total resistance?

5. In a 120 volt parallel circuit there are four devices. One requires 1/2 ampere, another

1/4 ampere, another 1-1/4 amperes, and the fourth 3 amperes. What is the total

current required?

6. What is the resistance of each device in problem 5? What is the total resistance?
