So I have a 12 v 1 amp power supply. I want to convert the current from 1 amp to 0.08 amp and keep the voltage the same. This is for a power a brushless fan; specs 12 v 0.08 amp. I am not sure how to do this. If anyone can help, I would appreciate it a lot. Thank you
Power supplies are available in a wide range of voltage and current ratings.  If I have a device that has specific voltage and current ratings, how do those relate to the power ratings I need to specify?  What if I don't know the device's specs, but am replacing a previous power supply with particular ratings?  Is it OK to go lower voltage, or should it always be higher?  What about current?  I don't want a 10 A supply to damage my 1 A device.
Is 45 mins enough in Newark airport terminal C to change the plane for connecting flight? We are having issues with our exchange 2013 server. The server is running Windows Server 2008 R2 Standard.  The issue we're having is that our Exchange server isn't receiving internet emails. It can currently send mail out to internet addresses, and send and receive internal emails from the current email server. I have checked the settings of the receive connectors and everything seems correct. We have tried everything that we can think of.   We can send and receive email locally, and send out to a gmail account. However, we don't get the reply email from the gmail account to the inbox.    Thanks in advance!!

Destroying a Planewalker before its ability is used Say my opponent plays a planeswalker during their first main phase.  I have a  or some other effect that will kill it after it is already in play, but before they use any of its abilities.  I could respond to them using a +1 ability, but I want to kill it before that effect goes on the stack.  In most casual situations, it would basically come down to whether I say "Hero's Downfall" first, or they say "+1" first.  But I can't imagine that's how it's supposed to work.  Is there a time between when the planeswalker hits the battlefield and when they activate its abilities that they must let me respond? It seems to me that situations like this arise frequently, and they are resolved simply by who speaks up first, which is horrible for such a rules-oriented game. Best way to track onchange as-you-type in input type="text"? In my experience, input type="text" onchange event usually occurs only after you leave (blur) the control.  Is there a way to force browser to trigger onchange every time textfield content changes? If not, what is the most elegant way to track this “manually”?  Using onkey* events is not reliable, since you can right-click the field and choose Paste, and this will change the field without any keyboard input.  Is setTimeout the only way?..

Proving the second root of a quadratic equation If $\alpha$ is a root of the equation $4x^2+2x-1=0$, then prove that $4\alpha^3-3\alpha$ is the other root. How do I proceed? The sum of the roots, the product of the roots lead me nowhere. Should I find the roots of the equation and substitute in the given two expressions of $\alpha$ and check whether manipulating the first root gives me the second root (which seems much complicated), or is there any other way? What does capital letter I mean in this formulas? Hello I don't understand meaning of the symbol represented by a capital letter "I" in the formulas below. There is  to the paper with the formulas.    At the beginning I thought it mean "where c is not equal to the result of classifier T(m)", however in step (d) there is a multiplication symbol before it, so it probably mean that "I" should "return" a value. Problem: Suppose $f$ is continuous for $x\ge 0$, differentiable for $x&gt;0$, $f(0)=0$, and $f'$ is monotonically increasing.  Define $g(x)=\frac{f(x)}{x}$ for $x&gt;0$. Prove that $g$ is monotonically increasing.  Source: W. Rudin, Principles of Mathematical Analysis, Chapter 5, exercise 6.

How to convert a currency string to a double with jQuery or Javascript? Reason for the current trend to use «she» as the gender-neutral pronoun? There are some questions on gender-neutral pronouns both  and on .  User Christine Letts :     In academia, there is currently a   movement toward using the feminine   pronoun at all times.   I wonder why that is. I came across several examples on papers I read, but the only one I can remember at the moment is a book: Seth Godin's . While some might not be comfortable labeling it as part of academia, it suits my point perfectly. Every time he refers to a person, he uses the feminine pronoun.  User Senseful  the following, potentially identifying affirmative action as the precursor for this trend.     I remember reading somewhere that it   was recommended to use the opposite of   what most people stereotype the   profession as. So, for example, when   talking about a chiropractor, you   would use "her", and when talking   about a secretary, you would use   "his".   So, where do you think this trend comes from? Let $f(z)=\frac{1}{(z-1)(z-2)}$ and $g(z)=\frac{z}{(z-1)(z-2)}$. Let $\gamma$ be the circle of radius 4 centered at the origin and traveled once in the counterclockwise direction. Let $A=\{ z \in \mathbb{C}: |z|&gt;3 \}$  1) I need to show there is no analytic function $G: A \to \mathbb{C}$ such that $G'(z)=g(z)$ for all $z$ in $A$.   2) I also need to show that there is an analytic function $F:A \to \mathbb{C}$ such that $F'(z)=f(z)$ for all $z$ in $A$.  Do I have to integrate to find such function? Explanation of terminal objects using limits I understand terminal objects, but I falter when trying to achieve them using the approach of diagrams, the category of constant diagrams $\mathcal{C}^{\mathcal{J}}$ and limits.  I have the empty category 0, now I have a diagram $D: \mathcal{J} \to \mathcal{C}$. However this diagrams image should be empty, because there are no objects or morphisms to map. At this point, I'm confused, because I can't get to the universal property $\forall c \in \mathcal{C}. \exists! f: c \to T$ anymore, because I'm missing T. (EDIT: I get that this is how it is supposed to be)  But continuing with the category of constant diagrams, even if I have a constant diagram mapping everything to one object / morphism, there is nothing to map, so the functors image is still empty. So now I'm missing both $T$, and any kind of $c$.  EDIT: It seems to me, have I chosen 1, instead of 0, I would have come up with that is considered the definition of the terminal category. What am I missing? I have several very similar images except some have some extra graphics that enlarge them slightly. This causes some pictures to be offset and not aligned visually when it's clear they should be.  How can I align several tikzpictures along the the same origin they were created and center vertically and horizontally properly?   First, I want to align the 3 large boxes regardless of the what the small boxes are doing Second, I want to be able to center them all without adding additional spaces the \begin{center} seems to do Third, I want to be able to reproduce the exact same results but everything in landscape mode without using the landscape package if possible. (as you can see, the problem is that TeX is putting one rectangle at a time which is not what I want) The methods should be easy and quick. I have many rectangles stacked and some need to be grouped arbitrarily. What these means is I want the methods to sort of be "smart" in that they can figure out themselves so I don't have to go change a lot of stuff each time I have to change the grouping. Basically I would like the first rectangle on the page to define the alignment location and the others on the same page to use it unless I tell them not to.   I've tried creating a custom bounding box as shown in  but it didn't do anything unless I make it too large which then causes other problems. (I can end up doing the alignment but it seems more complex than necessary)  \documentclass[10pt]{book} \usepackage{tikz}  \begin{document} \begin{tikzpicture}     \draw[line width=30pt] (0,0) -- (7,0); \end{tikzpicture}  \begin{tikzpicture}     \draw[line width=30pt] (0,0) -- (7,0);     \draw[line width=20pt] (-0.4, 0) -- (-0.1, 0); \end{tikzpicture}  \begin{tikzpicture}     \draw[line width=30pt] (0,0) -- (7,0);     \draw[line width=20pt] (-0.4, 0) -- (-0.1, 0);     \draw[line width=20pt] (-0.8, 0) -- (-0.5, 0); \end{tikzpicture}    \begin{center}% \begin{tikzpicture}%     \draw[line width=30pt] (0,0) -- (7,0); \end{tikzpicture}% \end{center}%  \begin{center}% \begin{tikzpicture}%     \draw[line width=30pt] (0,0) -- (7,0);     \draw[line width=20pt] (-0.4, 0) -- (-0.1, 0); \end{tikzpicture}% \end{center}%  \begin{center}% \begin{tikzpicture}%     \draw[line width=30pt] (0,0) -- (7,0);     \draw[line width=20pt] (-0.4, 0) -- (-0.1, 0);     \draw[line width=20pt] (-0.8, 0) -- (-0.5, 0); \end{tikzpicture}% \end{center}%     \begin{tikzpicture}%     \draw[line width=30pt] (0,0) -- (0,7); \end{tikzpicture}%   \begin{tikzpicture}%     \draw[line width=30pt] (0,0) -- (0,7);     \draw[line width=20pt] (0,-0.4) -- (0,-0.1); \end{tikzpicture}%  \begin{tikzpicture}%     \draw[line width=30pt] (0,0) -- (0,7);     \draw[line width=20pt] (0,-0.4) -- (0,-0.1);     \draw[line width=20pt] (0,-0.8) -- (0,-0.5); \end{tikzpicture}%    \begin{center}% \begin{tikzpicture}%     \draw[line width=30pt] (0,0) -- (0,7); \end{tikzpicture}% \end{center}   \begin{center}% \begin{tikzpicture}%     \draw[line width=30pt] (0,0) -- (0,7);     \draw[line width=20pt] (0,-0.4) -- (0,-0.1); \end{tikzpicture}% \end{center}%   \begin{center}% \begin{tikzpicture}%     \draw[line width=30pt] (0,0) -- (0,7);     \draw[line width=20pt] (0,-0.4) -- (0,-0.1);     \draw[line width=20pt] (0,-0.8) -- (0,-0.5); \end{tikzpicture}% \end{center}%   \end{document}
