    How Do You Calculate the Current in Each Wire When a Charge Moves Between Them?

    Does B1 = u0 I / 2 pi r, where r is the distance from the point to wire 1, and B2 is the same, but with r= the distance from the charge to the second wire?

    Solving a Basic RC Circuit: Charge on Capacitor from 537 to 195 μC

    Use the time constant equation for a drop: Qf= Qo e^-t/T, where T is the time constant, or R x C. You know or can find all of these variables, and solve the equation for t. Make sure you convert your C to Farads. I think this is correct. I'm only an undergrad student, but just had an exam...

    Change in Kinetic Energy of a moving charge

    Ok based on what you told me, I've calculated the voltage within the rectangular system. I know that the new charge will be in that system, so how do I find the initial EPE and final EPE?
