    Other Becoming an Engineer: Considerations and Personal Experiences

    I am a physics/math double major with one year left of college, and while I've really enjoyed studying both physics and math in my time here I am considering switching over to engineering for grad school. Although discovering how nature works appeals to me greatly, as far as careers go I think...

    Circuit with Resistors and Two Opposing EMFs

    Wow, so that is the correct magnitude? That's good. The direction should be counterclockwise, since the top emf is stronger than the bottom one, and the top one is going counterclockwise. And just for clarity I drew a rough sketch of the diagram:

    Circuit with Resistors and Two Opposing EMFs

    Homework Statement The circuit shown in Fig. 25.37 contains two batteries, each with an emf and an internal resistance, and two resistors. Find (a) the current in the circuit (magnitude and direction) . . . The circuit is a rectangle with the emfs at the top and bottom sides and the...
