1. Which electrical wire size has the largest diameter?

Explanation

The electrical wire size is determined by its gauge, with a lower gauge indicating a larger diameter. Therefore, the wire with the largest diameter would be the one with the lowest gauge. In this case, 12 Gauge has the lowest gauge among the given options, so it has the largest diameter.

2. If you have a rectified power source and the output has high ripple, what would could you use to cut the ripple?

Explanation

A capacitor can be used to cut the ripple in the output of a rectified power source. When connected in parallel with the load, the capacitor acts as a filter and smooths out the voltage waveform by storing and releasing electrical energy. It helps to reduce the amplitude of the ripple voltage, resulting in a more stable and regulated output.

3. In the early days of computers, what were 4 bits called?

Explanation

In the early days of computers, 4 bits were referred to as a "nibble". This term was used to describe a group of 4 binary digits, which could represent a single hexadecimal digit. The term "nibble" was coined as a play on words, combining the words "half" and "byte" to represent half of a byte, which consists of 8 bits. This term was commonly used in early computer systems and programming languages to describe a small unit of data.

4. Palm manufactures what type of computer?

Explanation

Palm manufactures handheld computers. Handheld computers are small, portable devices that can be held and operated with one hand. These devices are designed for personal and on-the-go use, offering features such as touchscreens, wireless connectivity, and various applications. Palm, a company known for its PalmPilot and Palm Treo devices, specializes in producing handheld computers that cater to the needs of individuals who require mobility and convenience in their computing devices.

5. How can you calculate the Xmax of a woofer?

Explanation

To calculate the Xmax of a woofer, one can measure the voice coil length, subtract the air gap height, and divide the result by 2. This method helps determine the maximum linear excursion of the woofer's cone, which is the maximum distance the cone can move forward or backward from its resting position. By subtracting the air gap height, which is the distance between the voice coil and the magnet, from the voice coil length, we can obtain an accurate measurement of the cone's maximum excursion. Dividing the result by 2 gives us the Xmax value.

6. The getter is a metal ring usually at the top of the vacuum tube. What is its main function?

Explanation

The correct answer is "To Consume Unwanted Gas Molecules." The getter in a vacuum tube is a metal ring that is used to remove or absorb any unwanted gas molecules that may be present in the tube. This helps to maintain a high vacuum inside the tube, which is necessary for the proper functioning of the tube. The getter acts as a trap for the gas molecules, preventing them from interfering with the electron flow and other processes happening inside the tube.

Submit
7. In a push-pull output stage, if a pentode vacuum tube is connected as a triode, which of the following will happen?

Explanation

When a pentode vacuum tube is connected as a triode in a push-pull output stage, the distortion is lowered and the output power is decreased. This is because the pentode tube, when operated as a triode, has a lower gain and higher internal resistance compared to its normal operation as a pentode. This results in a reduction in distortion but also a decrease in output power.

Submit
8. Which of the following statements best describe a class A transistor amplifier?

Explanation

A class A transistor amplifier is characterized by the fact that each transistor is in its active region for the entire signal cycle. This means that the transistor is conducting current for the entire duration of the input signal, allowing for a high level of amplification and accuracy in signal reproduction. This also means that the amplifier operates in a linear mode, without any distortion or clipping of the signal.

Submit
9. In class AB operation, the output transistors are arranged in complimentary pairs. What does a complimentary pair consist of?

Explanation

A complimentary pair consists of one NPN transistor and one PNP transistor. In class AB operation, these transistors are arranged in such a way that one conducts during the positive half cycle of the input signal while the other conducts during the negative half cycle. This arrangement allows for efficient amplification of the input signal with minimal distortion.

Submit
10. A 24 dB per octave filter is how many dB down at the crossover frequency?

Explanation

A 24 dB per octave filter is 6 dB down at the crossover frequency. This is because the crossover frequency is the point at which the filter starts attenuating the signal, and a 24 dB per octave filter attenuates the signal by 6 dB for every octave above the crossover frequency. Therefore, at the crossover frequency, the filter is 6 dB down.

Submit
11. The components in an IC chip are electrically isolated from each other by what?

Explanation

The components in an IC chip are electrically isolated from each other by Pn Junctions between each component and the P-Type Substrate. This is because Pn Junctions are formed by doping the silicon substrate with impurities to create regions of different electrical conductivity. The P-Type Substrate acts as a base for the components, and the Pn Junctions prevent the flow of current between the components, ensuring electrical isolation.

Submit
12. What is the frequency location, in megahertz(MHz), set aside by the FCC for citizen's band emergency channel 9?

Explanation

The correct answer is 27.065 MHz. The Federal Communications Commission (FCC) has set aside this frequency for the citizen's band emergency channel 9. This channel is designated for emergency communication purposes, allowing citizens to call for help or report emergencies.

Submit
13. Which processor uses memory bank switching signals?

Explanation

The 8086 processor uses memory bank switching signals. Memory bank switching is a technique used to access more memory than the processor's address space can directly handle. It allows the processor to switch between different memory banks, effectively expanding the available memory. The 8086 processor, which was introduced by Intel in 1978, was one of the first processors to support memory bank switching, making it capable of accessing larger amounts of memory compared to earlier processors.

Submit
14. What company makes the only microturbine?

Explanation

Capstone is the correct answer because it is the only company mentioned in the options that specializes in microturbines. Enertech, Whisper Technologies, and Electrion are not known for manufacturing microturbines. Therefore, Capstone is the most likely company that makes the only microturbine.

Submit
15. What is the value of a small capacitor marked 104?

Explanation

The value of a small capacitor marked 104 is .1 uF. Capacitors are often marked with a numerical code to represent their capacitance value. In this case, the code "104" indicates that the capacitance is 10 followed by 4 zeros, which translates to .1 uF.
