    Energy Dissipation Across a Resistor

    Homework Statement A battery is connected across a uniform resistor R0. A sliding contact can move across R0 from x=0 to x=10cm at the right. Moving the contact changes how much resistance R is to the left of the contact and how much is to the right. Find the rate at which energy is dissipated...

    Gauss's law and nonuniform electric field

    Ah, okay. I didn't know that. But when calculating the flux of individual faces, does the constant vector contribute?

    Gauss's law and nonuniform electric field

    Homework Statement A Gaussian surface is in the shape of a cube with edge length 1.40m. The electric field is E=[-4i+(6+3y)j]N/C. I got an answer, but the solution manual stated that we treat the electric field as E=3yj+E0, where E0=-4i+6j, which does not contribute to the flux. Why is...
