About RF Cafe Copyright: 1996 - 2024Webmaster:     BSEE - KB3UON 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. Dial-up 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...

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.

QUIZZES:

How Well Do You Know

BASIC ELECTRICITY?

Chapter 13

INDUCTION

1. What two factors control the direction of an induced emf?

2. What three factors control the strength of an induced emf?

3. How many circuits are necessary for mutual induction?

4. How many circuits are necessary to produce self-induction?

5. Will steady d.c. produce a continuous self-induction? Why?

6. State Lenz's law in simple language.

7. How may the voltage of self-induction be dangerous around a motor?

8. In what one way does pulsating d.c. differ from regular d.c.?

9. In what two ways does a.c. differ from regular d.c.?

Chapter 13

INDUCTION

1. Flux direction and the direction of cutting the flux.

2. Strength of the field, speed of the conductors, and number of conductors cutting.

3. At least two.

4. One.

5. No. The flux field must move to produce self induction.

6. For every force, there is an opposite force set up which tends to cancel the first force.

7. Open the field coil circuit may produce thousands of volts of self induction.

8. Pulsating d.c. varies in strength, regular d.c. does not.

9. A.c. varies in strength and direction, regular d.c. does not vary in either.
