| Hey, any physicists around? I need some help with homework. I have to find the frequency of a generator in hz, the angular speed, and the magnitude of the electric field. All I know is the cros-sectional area, the amount of turns, and I have a voltage vs time graph. Any help would be... helpful. Thank you. |

I found an equation that works: [D]v = [D]V(max) sin 2(pi)ft where [D] = delta/change in v = instantanious voltage V(max) = maximum voltage the olny problem is I'm not sure where to pull these numbers from. I have a voltage vs time graph- should I just pick out any space of time and fill it in? What do I take fot the inst. voltage?? Thanks. |
