Electricity  Basic Navy Training Courses NAVPERS 10622 
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. ¶ U.S. GOVERNMENT PRINTING OFFICE; 1945  618779 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 11/4 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?

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 World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dialup modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
