There are commercial products available called active noise cancellers, which consist of a set of headphones, microphone, and some electronics. Intended for wearing in noisy environments where the user must still be able to hear (for example, radio communications), the headphones reduce noise far beyond the simple acoustic isolation of the headphones. How does such a product work?

Hello.


When I look at circuit diagrams, they often seem to have lots of unecessary reistors.

They are in series with other components, or in series. I often wonder why they are there.

Thanks.

I have been using Kenmore Ultra fabric Care Heavy Duty 80 Series washer model # 110. 92284100, stock # 22841, serial # cc 3083945 for the last 10 years & performance was very good. Machine rating 120v, 60Hz, 10A. I shifted this machine to in Pakistan. Voltage is 220v, 50Hz. Used auto transformer rating: 2000VA, 127/220V, 50/60Hz. Primary 127V/16A, secondary 220V/10A. During running machine stopped w/o completing the cycle. The TX & machine cable became very hot. Measured input/output current as 8-9A/16-18A. I reduced input voltage thru another TX to 202V and output of 220/127V TX was reduced to 117V and currents measured again as 8A/14A. I have no option except to use at 220V, 50Hz with some transformer.
Need expert opinion/solution to reduce current below 10A so that machine could work without heating. Do I need to reduce the voltage to 100-105V, will it work and will it not heat up due to change of frequency. Please suggest.

I am going on my third year in college and am at the point where I NEED to figure out what I would like to do with the other 40 years of my life. After much research (and procrastination) I have been thinking about computer engineering. The thing is I only know what I have read about the field, which turns out to be emotionless textbook explinations.

This point is-

Would anyone be able to break down (as much as you would be willing to) what it is ACTUALLY like to be a computer engineer. Not so much the whole "Analyze requirements to develop overall hardware and software systems. Plan layouts and installation" definition I can find on any site. I am talking about the humane side of it. Such as-

What is it like starting out?
How long does it take to fully feel like that industry is you, and not like you are trying to make it that way?
Any regrets?
Is it more stressful or fun?

Anyone with any knowledge in the field that they are willing to offer would help me a lot!

I am trying to use 2 X 20Amp load current rated relays in parallel (both COMMOM tied together, both NO tied together, both NC tied together, both coils tied together) to run 40A load current. From electrical/theoretical standpoint it should work but I just have never seen any such implementation. My limitation is size as I can find a dual 20A relay in a much smaller height than a single 40A relay.

Because the Great Lakes are the largest fresh water lakes in the world, and actually considered inland seas because of their size, wouldn't constructing an aquaduct down through Texas prove beneficial to farmers in case of droughts or fires?
