Homework Statement
Two long parallel wires are separated by 4.0mm. The current in one of the wires is twice the other current. If the magnitude if the force on a 2.0m length of one of the wires is equal to 7.0μN, what is the greater of the two currents?Homework Equations...
Since the capacitor is at 50% of its maximum charge, then the potential difference across its plates is 55V. Does that mean that I would apply that 55V to the entire closed loop that contains bulb A and the capacitor? Would I treat bulb A as a resistor in series with C? Again, the geometry of...

This problem is giving me a headache. I feel certain that bulb B is the brightest when the capacitor has half its maximum charge. However, I am having a hard time coming up with equations for the circuit...
