1. To get the total resistance in a series circuit, all you need to do is add the resistance in each resistor.

The answer is C.

2. The unit of electricity that does the work in a circuit is the current and the unit of current is Ampere or A. Ampere is the flow of one coulomb per second.

The answer is D.

3. The Basic Parts of an Electric Circuit is an energy or power source, a conducting wire, electrical load or a device and a controller or a switch. A fuse can be included for protection.

The answer is D.

4. Kilo means 1,000. Like in kilograms, the base unit is grams and kilo means thousand, so in short it is a thousand grams. So if a meter shows 0.75 kiloohms then you multiply that by a thousand and you will get 750 ohms.

The answer is A.

5. A voltmeter is used to check for variable voltage output from an ignition sensor or computer. It measures the electrical potential difference between two points in a circuit. An analog meter is too general, a continuity light measures current flow and a logic probe analyzes logical states.

The answer is B.

6. The lines on an oscilloscope display are called a graticule. It is a type of electronic test instrument that is used to observe changes in an electrical signal over a period of time. The voltage and time shows a shape that is continually graphed based on a calibrated scale.

The answer is C.

7. Silver is actually the best conductor of electricity but it is very expensive and is not often used. If we look at your choices, the next best conductor would be copper. It is more commonly used because it is a lot cheaper.

The answer is C.

8. An antistatic sprat is a used to eliminate static electricity. It prevents static cling and not used to locate a short circuit. It is commonly used on clothes. It cannot be used on some electrical equipment like monitor screens.

The answer is B.

9. As temperature increases, the conductor increases in resistance. This is because the free electrons and the captive ones collide more as the temperature increases.

The answer to your question is C.

10. Without the illustration, we cannot answer this question.

11. It is true that current takes the path of least resistance, especially in a series circuit. However, current takes all paths available. If you look at a parallel circuit, the wiring is not in a continuous line but the current flows through all resistors that are in the circuit, unless the impedance is not greater than the current flowing.

The answer is D.

12. An analog scope uses a cathode ray tube (CRT) not an LCD display. The CRT is used to display the voltage patterns. This means that Technician A is incorrect. So you are left with Technician B.

The answer is A.

13. Milli means 1/1000. If the value is millivolt then that means that there are one thousandths of a volt. So if we convert your figure from 432 millivolts to volts, then we divide the value by 1000. The answer is then 0.432 volts.

The answer is C.

14. In a series circuit, the sum of the voltage drop should be equal to the applied voltage. The same current flows in each resistor and the part of the source voltage drops across each resistor. The total resistance in a series circuit is the sum of all the resistors in the circuit.

The answer is then A.

Refer to the attachment for the rest of the answers.

Read the passage from animal farm. one sunday morning squealer announced that the hens, who had just come in to lay again, must surrender their eggs. napoleon had accepted, through whymper, a contract for four hundred eggs a week. the price of these would pay for enough grain and meal to keep the farm going till summer came on and conditions were easier. when the hens heard this, they raised a terrible outcry. they had been warned earlier that this sacrifice might be necessary, but had not believed that it would really happen. they were just getting their clutches ready for the spring sitting, and they protested that to take the eggs away now was murder. for the first time since the expulsion of jones, there was something resembling a rebellion. led by three young black minorca pullets, the hens made a determined effort to thwart napoleon's wishes. their method was to fly up to the rafters and there lay their eggs, which smashed to pieces on the floor. napoleon acted swiftly and ruthlessly. he ordered the hens' rations to be stopped, and decreed that any animal giving so much as a grain of corn to a hen should be punished by death. the dogs saw to it that these orders were carried out. for five days the hens held out, then they capitulated and went back to their nesting boxes. nine hens had died in the meantime. their bodies were buried in the orchard, and it was given out that they had died of coccidiosis. whymper heard nothing of this affair, and the eggs were duly delivered, a grocer's van driving up to the farm once a week to take them away. which detail from the passage supports the claim that this is an allegory for the great purge? the hens holding out for five days but capitulating the eggs being delivered to the grocer the protesting hens being intentionally starved coccidiosis spreading on the farm
