Alternating Current Answers
Why they use words "AC","DC&q uot; (Alternating,Direct Current) for current and voltage? Why not using AV or DV?
Q. In electrical engineering, we use the words 'AC' and 'DC' a lot. All of us know that AC stands for alternating current, and DC stands for direct current. But the strange thing is, that we use it before current and voltage. We do not say, AC when we are talking about Alternating Current, or AV when we are talking about Alternating Voltage. Instead we say 'AC current' and 'AC voltage'. This also applys for the DC. I think it is a matter of old literature, but I wonder if any one can give me the correct reason (may be historical) for this. I am an Electrical Engineer. I ask this question seriously. Some people thought that I don't know the difference between voltage and current. This is not the question. The question is, why when we want to… [cont.]

Where does the electrical current orginate from a stimulus in a "graded potential"?
Q. How are stimili converted into electrical sources and transmitted as ions through a neural membrane?
Asked by Andrei C - Fri Apr 13 08:12:14 2007 - Psychology - 1 Answers - 1 Comments
A. In a graded potential...the electrical current originates from the dendrite of a neuron. Upon being stimulated, certain receptor protein ion channels on the dendrites are activated and opened. This causes an influx of the specific ion the receptor channel was geared for and depolarization results. The more intense the stimulus...the more ion channels that are opened...the greater the voltage change...and the farther the current flows (current reflects the movement of ions). These ions accumulate very close to the stimulated area. From there the surplus of ions radiates out in all directions, polarizing adjoining membranes.

Why is the French stimulus package more "pro-business" than the current proposed stimulus in the USA?
Q. "The French stimulus plan is split into three parts: 11bn euros to help businesses improve their cashflows; 11bn euros of direct state investment; and 4bn euros of investment by state-owned firms for modernising rail infrastructure, energy and the postal service. The government expects that the stimulus package will produce economic growth of around 1.3%"

How to swim out of a "turning current" of a dam?
Q. If you are swimming in a river and the river's current caries you into the dam downstream into the turning current "washing machine effect" which is basically and upside-down whirle pool, how do you get out of the dam??
Asked by Gina P - Wed Jan 28 05:53:53 2009 - Law Enforcement & Police - 2 Answers - Comments
A. Hold your breath if you are pulled under, the current will continue to pull and push you down and then away from the dam and then back again. You can gradually work your way farther from the standing wave and the dam. If you are on the bottom you can swim away from the dam as the water current is moving away from the dam, the wave on top pulls you toward the dam.

Can AC current "jump" across capacitor?
Q. "Jump" is obviously a misnomer, but if the positive lead on an AC source is applied to a capacitor, will the alternating voltages induce current flow on the other terminal?
Asked by GMCastanza - Tue Oct 20 00:39:10 2009 - Engineering - 3 Answers - Comments
A. A capacitor is essentially two parallel, conductive plates, separated by air or another "dielectric" (electrical insulator). Current does not jump across the plates, but instead flows into the plates causing electrons, or negative charge, to build up on one plate and postive charge to build up on the other plate. When the a.c. voltage reverses, current flows in the opposite direction, causing electrons to flow into the plate that was originally positive, and electrons to flow out of the plate that was originally negative. This reverses the charge on each plate. In this manner, a.c. current flows between the plates and the a.c. source without electrons jumping across the capacitor. When the power switch is intially closed, the… [cont.]
