Theoretical vs measured electrical resistance: Percent error relation
2019年4月20日 · Leads me to suggest that the resistors at the school came from the same manufacturing batch, and yours at home came from another. Or the resistors supplied to the school had a selection bias for laboratory material. And 3 resistors do not a trend make. You would have to test a whole lot more.
Do Harvard and MIT students have a 145 IQ average? - Physics …
2018年4月19日 · Because as pointed out, colleges don't directly measure the IQ of their students. Googling reveals that a number of people have tried to do academic quality research on this, but since you need to get volunteers, it is tough to eliminate selection bias in surveys. In any case...

2024年10月30日 · Logging my word selection process in this thread is to help me get a "feel" as I don't want to do formal data gathering (in a spreadsheet, for example). I know I'll get crazy about it if I do. Doing it this way gives me a good sense to help me keep track of my progress informally such that it stays fun and doesn't feel like a job.
Forward Bias: Why does width of depletion layer decrease?
2017年1月8日 · The depletion layer width affects the current flow by acting as a barrier to the flow of majority carriers. A narrower depletion layer means a smaller barrier and therefore, a higher current flow in the forward bias direction. In the reverse bias direction, a wider depletion layer means a larger barrier and therefore, a lower current flow.
Is New Scientist a Credible Source for Scientific Information?
2011年3月6日 · Does New Scientist have a bias towards certain scientific topics or theories? New Scientist strives to present unbiased and objective information on a wide range of scientific topics. However, like any publication, it may have a slight bias towards certain topics or theories based on the interests of its writers and readers. 3.
The predictive brain (Stimulus-Specific Error Prediction Neurons)
2024年7月21日 · Yes, and one idea is that this guidance or bias that "looks like decision making" is spontaneous self organisation, driven by evolution and selection. The challenge is to explain the correspondenc to "replication" in primordal systems that obviously can't replicate the way we are used to in higher biology or rna replucation.
What Is the Slope Resistance of a Zener Diode? - Physics Forums
2009年9月21日 · Look at the plot of the Current versus Voltage for the diode in forward and revers bias. In reverse bias, where the Zener diode starts to conduct, there is a slope to the curve. That slope can be thought of as a "resistance", if you linearize (average) it …
Optimal Course Selection for Math and Physics Students
2006年10月30日 · The timing of course selection varies depending on the institution and academic calendar. Generally, course selection takes place before the start of each academic term. This can range from a few weeks to a few months before the term begins, so it's important to check with your school's academic calendar for specific dates.
Why is there a phase change in reflection and why is it always \pi?
2011年10月1日 · Ok, I studied better this topic in today optical physics, so now I can answer to you properly :D Some conventions: [itex]n=\frac{n_2}{n_1}[/itex], where n1 is the first medium and n2 the second, so that you have internal reflection for n<1;
What happens in a circuit that has a capacitor in parallel with a …
2012年2月5日 · Model the diode as a resistor in the forward bias, and an open circuit in the reversed bias. Suppose [itex]v(t)[/itex] is the potential, and [itex]i(t)[/itex] is the current through the external circuit, and let [itex]\varepsilon(t)[/itex] be the e.m.f. of the source. Then, the circuit equations become: [tex]
