If you take the actual test and do not pass, you will have to wait six months or more to take the test again! Take the practice test. Give yourself 25 minutes to complete the test; this approximates the time you will be given to complete the actual test the actual test is 60 questions in one hour which averages one minute per question.

Read each question carefully. Use the Reference Sheet on page 8 to find the figures and formulas you will need. Pick the best answer for each question and write the letter of your answer on a piece of paper.

Use the key on page 9 to score it. Review the explanations, starting on page 9, for questions you missed or were unsure of. Look up your score on page 11 to see how well you are likely to do on the real test. Which of the following wires has the greatest cross-sectional area?

Make a list of the questions you missed or got right but were unsure of. Review the explanation of those questions on the following pages.

The smaller the value of AWG, the greater the cross-sectional area of the wire. The 9 AWG wire will have the greatest crosssectional area of any of the choices. C Electrical pressure is the push given to electrons that causes them to flow through circuits. The unit of measure for electrical pressure is the volt. A In a series circuit, the current is equal at each point in the circuit and voltage is divided among the circuit components.

In a parallel circuit, the voltage across each component is the same and the current is divided among the separate branches. C Increasing temperatures cause electrons to be more active. The random nature of the increased activity causes collisions between thermally excited electrons and current carrying electrons.

The collisions tend to disrupt the flow of electrons through the circuit. This disruption reduces the net current flow. B Resistive elements in a circuit dissipate energy in the form of heat. Resistors connected in series are added to get total resistance. First, use Ohm's law to find the current I.

B Because the voltage drop across each component of a parallel circuit is the same, Ohm's law can be used to find the current in each branch.

The total current is then found by adding the current in each branch. Since in this case, the branches have equal resistance, simply find the current in one branch and multiply by the number of branches. As resistance R decreases, current I increases. C The symbol for an energy source, in this case a battery, is symbol I.

C In a reactive circuit, the higher value of reactance will determine whether the circuit is capacitive or inductive. Here, the capacitive reactance is higher than the inductive reactance. Therefore, the circuit is capacitive. D Electricity delivered to a wall outlet is stated in terms of rms voltage. A standard multimeter provides a reading of AC voltage in terms of rms.

B When a DC voltage is applied across a capacitor, there will be an initial flow of current. As the voltage across the capacitor charges up to the value of the source voltage, current flow will slowly decline.

At the point where the voltage is approximately equal, all current in this circuit will stop flowing because there is no difference of potential.

D A capacitor is a device that stores electrical energy. C Capacitors in parallel are measured like resistors in series. Add the three capacitors to get the total capacitance of the circuit. B Magnetic flux is created as alternating current changes direction and causes lines of flux to vary in the magnetic field.

As the lines of flux vary, they cause current to flow in nearby conductors. D The Henry is a unit of measure for induction. C Ohmmeters are used for testing continuity. Inductor windings are usually coils of wire and if not broken, can be tested with an ohmmeter for continuity.

A MOVs react very quickly to over-voltage conditions. When the voltage threshold of a MOV is exceeded, it instantly acts as a conductor, shorting the transient spike to ground. MOVs are commonly used to protect equipment that is attached to a transmission line. B A fuse responds to an over-current condition by opening. This separates the source from the circuit in the event of an overload.

Therefore it should be connected so that it is between the source of energy and the circuit-in series with the load. If the protection device see question 21 works properly, it will open a circuit if current goes beyond its designed current carrying ability. A Voltmeters measure difference of potential in electrical circuits.

C Polarity is of major importance in direct current circuits. Voltmeters are sensitive to polarity when making measurements in DC circuits. Correct placement of leads is very important when making these kinds of measurements. The Practice Test questions are very similar to-but not the same as-the questions you'll see on the real test. Your Practice Test score will give you a good idea of how well you could expect to do on the real test but, of course, only your score on the real test counts.

Find your score level below to get a good idea of how well prepared for the test you are right now. If your Practice Test score was… Congratulations! You are ready to take the real test and should have an excellent chance of qualifying. Get ready for the test with the help of the hints in the next section. If you took the real test now, you would have a fair chance of qualifying.

You can improve the odds if you review your weak areas first. See the next section. Use the next section to plan a study strategy.

If you're still interested in taking the test, take a course. Find out what to look for in the next section. Correspondence CoursesIf you scored in the mid-teens on the practice test and feel that you need guidance with studying, then a correspondence course can be a flexible and efficient way to further your education. Sources are found for eligible regular full-time or regular part-time employees for candidates who are not eligible employees.

Math SkillsDon't forget the math and calculator skills because you'll need them right away. If you don't know how to solve simple equations or work confidently with negative numbers and decimals, get these skills first. If you know the math basics, you can probably start right in with a basic electricity course. For example:For example: Q: What is an amplifier? A: A device that makes sounds louder and signal levels greater Q: What device is used to convert direct current to alternating current?

A: Oscillator Q: How does a digital meter's display differ from an analog meter's display? For example: Q: Holding resistance constant, how does increasing current in a circuit affect voltage? You will be asked to explain what's happening or what's wrong.

For example: Q: When measuring DC voltage across a device with a multimeter, the meter indicates 0 volts. What is one possible explanation for this reading? A: Switch is open Q: What is the resistance of a lamp which draws mA when connected to a For example: Q: How should a multimeter's leads be connected when measuring resistance? A: Connect the test leads to the terminals on the tested device As temperature increases, what happens to the current-carrying ability of a wire?

There is no change. The wire can carry more current. The wire can carry less current. The wire can carry no current.

Я сам попытался отправить твой маячок, но ты использовала для него один из новейших гибридных языков, и мне не удалось привести его в действие. Он посылал какую-то тарабарщину. В конце концов пришлось смирить гордыню и вызвать тебя. Сьюзан это позабавило. Стратмор был блестящими программистом-криптографом, но его диапазон был ограничен работой с алгоритмами и тонкости этой не столь уж изощренной и устаревшей технологии программирования часто от него ускользали.

Сотрудники почтительно кланялись, когда он проходил мимо. Нуматака хорошо понимал, что эти поклоны вовсе не свидетельствует об их любви к нему, они - всего лишь знак вежливости, которую японские служащие проявляют по отношению даже к самым ненавистным начальникам. Нуматака проследовал прямо на коммутатор компании. Все звонки принимались единственным оператором на двенадцатиканальный терминал Коренсо-2000. Телефонистка, державшая трубку у уха, мгновенно поднялась и поклонилась, увидев босса. - Садитесь! - рявкнул Нуматака.

Диаграмма чем-то напоминала бычий глаз. В центре находился красный кружок с надписью БАЗА, вокруг которого располагались пять концентрических окружностей разной толщины и разного цвета. Внешняя окружность была затуманена и казалась почти прозрачной.
