    Combining Resistors and Capacitors

    Doesn't that just say the current at each junction is constant, and the voltage in each loop is zero? I am not too sure where you are going with this, though...

    Combining Resistors and Capacitors

    Homework Statement This is like related to a homework problem, but I'm just curious: If we have two capacitors and two resistors in series, the overall capacitance and resistance does not change regardless of the order, right? Likewise, if they were in parallel (like a resistor + capacitor...

    Force between perpendicular wires in the same plane

    OK, thanks for clearing things up :)

    Force between perpendicular wires in the same plane

    OK, so there WOULD be a force on the horizontal wire, right?

    Force between perpendicular wires in the same plane

    Hmmm... I don't see how the current and magnetic fields would be perpendicular... sorry I'm so dumb T_T but in the [very crudely drawn] diagram, imagine the current in the vertical wire is going upward. So that means, the magnetic field would be going into the page to the right of the wire...

    Force between perpendicular wires in the same plane

    I meant to say, wire segment part of a (probably) infinite wire. Sorry. In that case, would there be a force?

    Force between perpendicular wires in the same plane

    Homework Statement I was just wondering, so lets say there are two current carrying wires in the same plane that are perpendicular. One of them is infinite length, the other is a wire segment some distance away from the first one and perpendicular to it. What's the force on the wire...

    Equivalent Capacitance of Complex Circuit

    can you do Kirchoff's Law for this problem? How would you take into account the initial part before the loops and the last wire after the loops?

    Equivalent Capacitance of Complex Circuit

    ehild, thank you so much! Since the voltage across it is zero, it's like the 3C capacitor isn't there, right? Solving the simple circuit then gives 4/3 C, which is the correct answer. Is my way of solving it correct? Or did I simply get the right answer the wrong way? Many thanks...

    Equivalent Capacitance of Complex Circuit

    Homework Statement Determine the equivalent capacitance of the combination shown in Figure P26.75. Suggestion: Consider the symmetry involved. Homework Equations Parallel is: C1+C2+C3+... Series is: (C1^-1 + C2^-1 + C3^-1 + ...)^-1 q = CV The Attempt at a Solution I have no...

    Person inside an isolated conductor

    Homework Statement You are inside a large, hollow conductor that is isolated from the ground. There is a large charge on the conductor. If you touch the inside of it, will you be harmed? What if you had a charge with opposite sign of that on the conductor? Homework Equations N/A...
