We have 6 results for Electric potential.
1 Citation As promised in the post dated 20th June 2008, we will discuss a few more multiple choice questions on electric field and potential. The following questions are meant for AP Physics B as well as AP Physics C: (1) Three positive charges each of magnitude q are arranged symmetrically along the circumference of a circle of radius r. The electric field at the centre of the circle has magnitude (a) 3q /4??0r2 (b) ?3q /4??0r2 (c) q/4??0r2 (d) (1+?2)q/4??0r2 (e) zero The electric field at any point, technorati.com

AP Physics B and C- Electrostatics: Free Response Practice Questions on Electric Field and Potential 1 Citation The following free response practice question which carries 15 points is to be answered in about 17 minutes and is meant for AP Physics B. But it will be useful to AP Physics C aspirants as well: Two identical thin rings of radius R are arranged coaxially with a separation R. A charge +Q is sprayed uniformly on one ring while a charge ?Q is sprayed uniformly on the other. (a) Calculate the electric potentials at the centres of the rings (b) What is the electric potential on the common axis, mi, technorati.com

1 Citation In the post dated 5th June 2008, two free response practice questions on electric field and potential were given to you. As promised, I give below model answers along with the questions: (1) Two identical thin rings of radius R are arranged coaxially with a separation R. A charge +Q is sprayed uniformly on one ring while a charge ?Q is sprayed uniformly on the other. (a) Calculate the electric potentials at the centres of the rings (b) What is the electric potential on the common axis, midway be, technorati.com

Christmas tree lights - surprisingly cool 1 Citation Let me start off by saying I think I first read about this on HowStuffWorks.com (many years ago). So, why are christmas lights so cool? They are cool because they are a whole bunch of lights in series, but they still work if one of the bulbs gets burnt out. If you are not familiar with circuits, a series circuit is one in which all of the current goes through all of the items in that circuit (as compared to the case where the current gets split up). Here is an example of a series circuit with t, technorati.com

BHO Anti-Static Wristband Eliminates The Need For A Ground Wire 1 Citation By Luke Anderson I remember the good old days of being a full-time networking/PC tech. I had my workbench where I did all of the major internal work on the computers that came in. I always had a couple of static wrist straps lying around (I had a tendency to wear them home and forget them), and I always hated using them. That stupid cord always got in the way of everything, though at least the ones I used let you remove the cord from the band, which was about as convenient as it got. Well no, technorati.com
