• Is there any degree that guarantees you a job.?

    Best answer: You'll do far better as an engineer than most graduates. At least you're not thinking of studying art history or philosophy or something equally useless. I was an engineer and everyone in my class got a job within 6 months of graduating (including me). An engineering degree is very versatile too -- you... show more
    Best answer: You'll do far better as an engineer than most graduates. At least you're not thinking of studying art history or philosophy or something equally useless. I was an engineer and everyone in my class got a job within 6 months of graduating (including me). An engineering degree is very versatile too -- you could study civil and work in software engineering, or study electrical and work in mechanical. It's pretty common.

  • What to do with 1 spare battery, too many in pack and unsafe to use with old ones?

    I don't want to risk breaking or leaking of the device, especially since it's a headlamp, I bought a pack of batteries but only needed 3, one has been sat in a wooden box. The batteries are getting low. Do I buy a new pack and then have wasted another battery or waste money on a device that takes one AAA... show more

Do I buy a new pack and then have wasted another battery or waste money on a device that takes one AAA battery if there is anything... nobody else I know wants one battery.

  • Note: this question is from the lecture called "scientific understanding of western music"?

    Which of the following is NOT a good reason why it was important to convert mechanical vibrations into electrical signals?(in terms of music sound) 1. Electrical signals can be stored for a long time without loss. 2. Electrical signals can be amplified after it has become weak. 3. Electrical signals... show more

Electrical signals can be stored for a long time without loss. 2. Electrical signals can be amplified after it has become weak. 3. Electrical signals can be delivered to many people at fast speed. 4. Electrical signals can be filtered to improve the quality of sound.

  • [Arduino/electronics question] why isn't the analog data I am receiving from a linear potentiometer also linear?

    I have a plunger potentiometer that I know to be quite linear in terms of resitance taper. The image with the y scale on the order of thousands shows this, using data I collected myself. The second image shows the voltage measured by an analog input pin on an Arduino UNO, where the reading is coming from the wiper... show more
    I have a plunger potentiometer that I know to be quite linear in terms of resitance taper. The image with the y scale on the order of thousands shows this, using data I collected myself. The second image shows the voltage measured by an analog input pin on an Arduino UNO, where the reading is coming from the wiper and the potentiometer is acting as a potential divider, with the same Arduino's ground and +5v connected across it. I can't figure out why the two charts don't look almost identical, save for a different y scale. My guess is that this must be caused by the +5v from the arduino being non-constant (but the Arduino has a voltage regulator no??) . In both cases the x axis represents mm of travel of the pot shaft.

  • What if the Egyptians had decided to build the pyramids higher?

    Best answer: It could be built to the height of a high mountain if resources were not an issue, which is probably in the region of 5 or so miles. After that it becomes an issue of geology versus gravity, with the increasing weight making it sink into the ground. On the practicality front, the issue is that going higher and... show more
    Best answer: It could be built to the height of a high mountain if resources were not an issue, which is probably in the region of 5 or so miles. After that it becomes an issue of geology versus gravity, with the increasing weight making it sink into the ground.

    On the practicality front, the issue is that going higher and higher is a cubic law.
    So for instance, to increase by 150m when doubling from 150m to 300m increases the volume by
    2^3 - 1^3 = 7
    ie it needs an additional 7 times the material

    But increasing by 150m to go from 9 times the height to 10 times the height increases the volume by
    10^3 - 9^3 = 271
    ie the increase in height of 150m from 9 to 10 times requires 271 times the whole original volume,
    and the whole thing would be 1,000 times the volume of material.

  • Diodes conduct under both biasing conditions?

    Best answer: Yes, a Diode has a reverse Voltage breakdown. This is where a Zener Diode works. Go to your library and check out a book on Diodes. There are hundreds of them made to perform many different types of magic.
