ELECTRICAL AND COMPUTER ENGINEERING FINAL EXAM
PREDICTION WITH PRECISE ANSWERS 11
1. Electrical engineering - correct answer the design and construction of electrical and
electronic components and devices.
2. Electric - correct answer take electric current and covert it to energy in simple ways, such as
light, heat, or motion. Generally, refers to high power devices (ex: generators, motors,
lamps, power stations, and house wiring.)
3. Electronic - correct answer designed to manipulate the electrical current itself to coax it
into doing interesting and useful things. (ex: computers, remotes, and cell phones.)
4. Communication systems - correct answer radio frequency, telecommunications,
networking, and fiber optics.
5. Power systems - correct answer energy conversion and distribution and alternate power
sources.
6. Control systems - correct answer microprocessor design, circuit design, and robotics.
7. Magnetism - correct answer generators produce electricity by changing mechanical energy
to electrical energy.
8. Induction
- correct answer voltage induced in wire when magnet passes it.
9. Cells use _______ _______ to create electricity. - correct answer Chemical action
10. Battery - correct answer multiple connected cells.
, 11. Electrode - correct answer a solid conductor through which electricity enters or leaves.
12. Static electricity - correct answer excess charge on an objects surface.
13. Conductor - correct answer anything that allows current to flow, such as copper wire.
14. Voltage - correct answer - electrical force that causes electrons to move.
- energy per unit charge.
- measured in volts.
15. Current - correct answer - rate of flow of electrons.
-measured in amperes or amps (a).
16. 1 ampere = correct answers- 1 unit of charge passing a point in 1 second.
17. Conventional current flow - correct answer current flows from negative to positive.
18. Electron flow theory - correct answer electrons move from positive to negative.
19. Polarity - correct answer positive or negative condition at power supply.
20. Alternating current (ac) - correct answer - polarity changes back and forth. When the
voltage reverses, so does the direction of the current flow.
- _______ _______ is used in nearly all the world's power distribution systems for
the simple reason that ac current is much more efficient when it's transmitted
through wires over long distances.
- in the us, the current/voltage reverses itself once every 60 seconds: 60hz.
21. Direct current (dc) - correct answer - current that flows continuously in a single direction
and supplies constant voltage.
- polarity is constant.
