Volt/Hz 176V / 60 ? Offtopic The motor appears to quite beefy from those specs, is it a traction motor? If it is a traction motor for a motor vehicle, driving it closed (FOC) loop will be nigh...
Actually I think this is a really good question. It's kind of more historical though I guess (and I don't know the historical answer either, but from building products perspective I think this is...
I used to live in the United States, and my microwave ovens' turntables turned at six rotations per minute (RPM). I now live in Israel, and my microwave oven's turntable rotates at five RPM. Annoye...
I have no record in electrical engineering; this is a total outsider question which might be grasped absurd. Wikipedia defines EMP as: An electromagnetic pulse (EMP), also sometimes called a tr...

Here is a video of the AN/PRM10, and here is a schematic (I believe the image can be zoomed): As most commercial grid dip meters produced in the past, this one possesses several functions in ad...
As an alternative to doing the math, as detailed in Andy's answer, you can use a graphical aid called a Smith chart: These were used routinely before computers to match transmitters to antennas. ...
$\color{purple}{\text{Are we there yet?}}$ No, it's not ready: - The embed image doesn't seem to work anymore on the EE part of the site and neither does it work here. It did yesterday because I a...
A work around has been found for this and I'm sure this will get a proper fix before long: - Go to the edit button for your answer (for example) and press it Notice that there is no live preview s...
I recall vividly a story told by my grandfather who worked with high voltage power lines. A worker drove heavy machinery into 700kV line and then jumped out of the truck, instantly combusting upon ...
How to find the equation of voltage of the top common node of R1,L1 and C1 after the switch is moved?
Assume a app generates a message (stack on computer).Each layer of the sending entity will put then control information in the data depending on the protocol and transmit the data to the next lowe...
Suppose we have this graph: How can we find the operating point (Q)?In common emitter collector we just draw a line from the vertical axis (Ic) at the point (0,VCC/RC) to the horizontal axis a...
I've upvoted the post of Olin because I think this is obviously better than the current situation. Nevertheless, this does not completely solve the problem of trolls using multiple accounts. I thin...
How to find the equation of current of the RLC circuit after the switch is moved?
I have a question about this circuit:(critically damped oscillation) For a critically damped oscillation for a series RLC circuit the equation of current has this form I(t)=D1te^(-at)+D2e^(-at) ...
I think they should have the same rep as ordinary posts. If they are high quality they will eventually accumulate a lot of up-votes over time. That's how the voting system is supposed to work, rewa...
In the past, a large number of new active building blocks have been proposed and published by many researchers all over the world. In most cases, these new building blocks were used for realizing n...
Discrete sets, as ℕ ℤ and ℚ, are in bijection within themselves, and the number of elements in them is Aleph (א) sub zero. Continuum sets as ℝ or 𝕀 are not in bijection to the former ℕ ℤ ℚ, and th...
I was analyzing the design a hazard warning light.The spec of the light turn on off is given below. The flashing-light frequency shall be 90+/-30 times per minute. May I know in this case the...
May I know how to calculate a signals rise time from it's frequency. I found this article for the same. The formula given is Tr = 1/f*π. May I know is this applicable for PWM also.
Hello, I want to understand the math of the phenomena of capacitor as temporarary means of increasing the current supply. First I have created a current limited voltage source which give me 45V a...
Hello,i need to drive 5 mosfets as shown below. Each mosfet draws 15A when the pulse opens the mosfet. My power supply is gives the 48V but only 3.3A,If I understand correctly I need to put very...
What are closest free or low-cost alternatives to software like Ansys PCB modelling? https://www.ansys.com/blog/optimize-your-pcb It's too costly for study purposes. To clarify: I am looking fo...
