when a capacitor is charged the values for charge upon each plate (surface) are equal in magnitude but opposite in sign. The total charge on the system is 14 uC. The total potential stored is 14V.
thus total capacitance = Q/Vab= 14uC/14V= (14*10^-6)C/(14*10^0)V=1uF.
I think that you lost a...
Note that resistance is a type of impedance but that impedance is not necessarily just resistance but something that comes up with AC called reactance or both.
When devices are placed in parallel, voltage is the same through all branches (unless a capacitor is in one branch) and charge (and...
The one thing to be observant about when purchasing a newer agp card for an older system is the voltage compatibility issue. Don't worry the cards are keyed to only fit into a voltage compatible slot, but by researching thoroughly before purchasing, mail order returns or extra trips to the store...
I am an electronics student as well. The way that I learned it was that a current source implied a resistance that was present even if the source happened to be turned off, i.e. the equivalent circuit to represent the internals is an idealized current source in parallel with a resistor...
I read something a while back that basically stated it is mathematically possible to define the laws of physics in any number of any type of the dimension we experience (space and time). The reason that we do not is basically Occam's razor. This is part of the issues with string theory for...
Um didn't they recently discover that the rate of expansion was not only increasing but accerlating? Doesn't that throw some of that expanation out the window so to speak?
I think Einstein used the term determinism, or at least his camp did to desribe Relativity and classical mechanics, whereas they used the term indeterminism to describe quantuam mechanics, chromodynamics, or whatever the quantum catch phrase is now.
In a deterministic universe, one could be...
The moon does not exactly orbit the earth, they orbit each other or I guess more properly, a common center of mass.
If you mean that you want to say balance the repulsive force of two magnets with some force or forces acting in the opposite direction, yes, you just have to engineer that...
I do not think HAARP and its sister installations are for weather modification. I think the military dual use is as part of SDI. Permanent heat pumps, as I proposed above, is a more likely means of weather alteration.
Thanks for finding the bill btw, I had not yet had time to go over to the...
Nature has killed more species than any other method. 99.9..% of species which have ever existed on this planet were extinct before homo sapiens ever walked the Earth.
Homo sapiens are a part of the biosphere. As a species we have made mistakes but like any other species we have an inherent...
Well here is a thought on similar lines. This idea derives from the siphoning used in OTEC. Basically set up a vast series of pumps from the bottom or near the bottom of the ocean to relatively close to the surface. When a hurricane is coming pump the cool ocean bottom water to the surface. This...
