Thanks for the direction. I'm wanting to do some example problems and calculations to get a feel for the magnitudes of the fields relative to a source I'm familiar with. What got me interested in this was an experiment with a generator with no load connected. It seems to me that if dB/dt was...
I'm doing my best at learning electricity & magnetism for the first time and I could use some help. Let's say I have two horizontal bar magnets moving horizontally towards each other at constant velocity. The changing B field should induce an electric field gradient in the perpendicular...
hmmm
I understand that the rate of diffusion is independent for x and y, but if I'm measuring distribution over many "shots" and it's moving in y than I'll be probing a different point at each measurement. The distribution will appear broader when y ≠ 0, correct?
I'd avoided explaining for fear it might devolve off topic, but here goes. My question is not actually directly related to statistics but I have reason to assume a normal distribution so it seemed like a good place to pose the question. I have a 2D distribution of particles injected into a gas...
Follow up question. I get that if I know σ_μ than I can back out σ. Now if the distribution is bivariate such that the trace I see is actually g(x,y=0) and I also have some variation in the mean of y, is there a simple way to relate the mean of y to the resulting sigma_x? In other words, I will...
Sorry again for the poor explanation. Because of the nature of the experiment, I can't measure the mean directly from each trace, but I can infer the deviation of the mean indirectly from other data.
Let me clarify. I'm running an experiment for which each result (what I called point) is a trace that gives a distribution. Based on the nature of the experiment, the standard deviation should be the same for each trace. However, there is a random shift of the mean that can obviously be...
I have an experiment in which I want to extract the distribution function of a process. I expect it to be Gaussian. Each data point measured is an entire distribution, f(x), but I am forced to average over many points such that the result of the experiment is the sum of many measurements of...
Something I've yet to understand: If a molecule has a dipole moment about a given access than absorption of a photon can readily occur. However, if it is possible to preferentially orient molecules by applying an electric field, would the rate of absorption be greatly increased or decreased? It...
In grad school, I worked with two types of math majors who had decided to work in the engineering department. The first were statistics folks who worked in risk/reliability for the nuclear engineering department. However, most of the math majors I've worked with were developing numerical models...
Baluncore. Thanks for the clarification. I'll see if I can work out the specs for the components I need and check availability. The series option isn't something I would have thought of.
Thanks to all for discussion.
Baluncore - Thanks. I don't want to suppress the spike from the load so I can't just add a snubber, so you're saying I need to add a choke between the load and the added parallel capacitor. To my knowledge, a choke is a type of inductor. If so, the RL time constant needs to be greater than the...
On practice: As an ME learning EE, I'm wondering if there is a textbook (or web page, etc) that has a large number of example problems with solutions. For example, mechanics people can look at the Hibbler books and corresponding solutions for hundreds of mechanics problems. If someone has a...
