Two parallel wires carry currents I1=100A and I2 (they run in the same direction). The top wire is held in position; the bottom wire is prevented from moving sideways but can slide up and down without friction. if the wires have a mass of 10g/meter of length, calculate I2 such...

Two identical thin wires are oriented along the x and y axes. With current on x plane going North. Current on y plane going West.Both carry the same current I, and there is no electrical contact between the wires. The points A, B, C, D are each equidistant from both wires. A: ...

Physics 2
If the currents are flowing in the same direction, they repel one another and you take the difference of I for wires in parallel with each other. If they flow in the same direction you take the sum of I. Do that for both sides of parallel lines and add your equations then set ...

Physics
The wire in the drawing carries a current of 14 A. Suppose that a second long, straight wire is placed right next to this wire. The current in the second wire is 33 A. Use Ampere's law to find the magnitude of the magnetic field at a distance of r = 1.0 m from the wires ...
