Hi all, I'm attempting to build a jumping ring apparatus (a core of iron with the bottom wrapped with wiring like an electromagnet, so that when a metal ring is placed on top of the coil and a current is run through the coil, the ring jumps up into the air). Looking on the internet, I'm seeing a...

I have a 30V - 100A power supply that I want to control using a -/+ 10V NI DAQ. I want a relay between the current output of DAQ and the power supply. Please advise the specification of relay to use. I'd appreciate a comment on how to connect it also.

Hi everyone, I'm new here but I've come across PF many times as viewer while searching for clarifications and exercise solutions. I think this should be the right place to ask for advice. My background: 30-ish years old, got my BSc and MS in Electrical Engineering in 2017. The courses were...

Hi everyone, I have a EE problem that I need to sort out for alternating voltage. I have to find out the maximum flux density. B_max= integral from 150 degrees to 30 degrees (u/(2NA) dt is my problem. I have a hard time to integrate this since I am to integrate with time and not degrees or...

Hello, I'm trying to decide between physics and electrical engineering. I like building electrical stuff, and I like solving physics problems, but my main goal is to try to build power systems that integrate things like what can be found in this paper https://arxiv.org/abs/1401.0520. I would...

Long time lurker, first time poster. I did my undergrad in EE. I'm looking to transition into something in the biomedical space, particularly tissue engineering. I might want to do a PhD, but I'm just seeking a new challenge at this point in my life. Is there any way that I can work part-time...

I'm an undergraduate EE student, the last few semesters I have been taking courses in telecommunications. I took an introduction to telecommunications course, a course on data communications, and a course on digital communications. I have not taken a course on wireless communications and will...

Hello dear community, my name is Elias and I study electrical engineering. I am in this forum to share my knowledge by trying to answer the questions of others and if I have any questions, I would be happy if I can be helped.

I am trying my hands on building receivers and transmitters. For now I would like to build this receiver here: now I see that the 500pH inductor in parallel witht he 200uH capacitor are in charge of filtering the unwanted frequencies. The top-left NPN is in my guess an emitter follower to...

I am close to graduating as an EE major but I have never been able to organize a step by step method on analyzing a circuit. It seems to me that every time I am trying to analize a circuit I end up with a bunch of equations and nothing more. I know that I should: 1. Know what I am solving for...

How did you find PF?: Google search I got a problem, how to calculate this formula from euler to imajiner? or how calculate this case?

Well, I have one nice problem. I have 30x10mm busbar, and Isc=30kA. I must place this busbars in electrical panel, but I have a problem with insulators. Can I use a red insolators as it's showed on picture, or I should use special holders for busbar system. Another problem is: When I use such...

The open loop voltage gain is given as : $$ u(s) = \frac{u_o}{1+\frac{s}{w_o}} = \frac{100}{1 + \frac{s}{40}}$$ Where u_o is the d.c. voltage gain and w_o is the pole. The op amp that is given is: And I am told to use the non ideal op amp model as follows: Well my guess is that I can find the...

Summary: Facing a circuit with 2 parallel resistors and 2 current sources (1 dependent, 1 independent). Trying to find the current, voltage, power delivered by the independent current source and power delivered by the dependent current source. I'm trying to start by finding the current i0 but...

So I'm a freshman in college right now and I am a physics major. The class I am also having most trouble with is...physics. I am doing great in math but physics is tougher for me. I was thinking that maybe physics isn't for me, as also looking around I realized just how theory-based everything...

Hi there, If you look through the trilogy of "Back to the Future" you come across many devices of Doc Brown. He's officially a physicist with theoretical knowledge, he's always claiming to conducting experiments, and he's great in building things...obviously. First question: what branch of...

I'm really interested in electrical engineering but I don't feel it's worth getting a degree in it to get involved it it. Is it self-teachable also I'm more interested in math. I'm 26 and was able to do a couple of calculus problems while staying in a hospital also I was able to calculate a...

How do I find electrical engineering jobs that aren't hardware based? I am looking for jobs that are more software/programming/statistical based work. My undergraduate was in economics and mathematics. My masters is in electrical engineering with an emphasis in communications. When searching for...

How common is it for electrical engineers to not particularly like programming very much? A bit more background: I go to a school in which the electrical engineering and the computer science department are very much intertwined, and so there's a big focus on computers in the EE curriculum...

Currently in my 3rd year in college of engineering, and I recently got offered a HV electrician intern for the DoD. Is worth taking? Being that its different towards my degree.
