Abstract: Current distribution between X-pinches and current-return rods was studied, considering the effect of mutual influence between different branches. In the experiment of current distribution between an X-pinch and a copper current-return rod, the current in the X-pinch is roughly the same as that in the current-return rod, which reflects that current division depends not only on the characteristic of the wires/rods, but also on the features of the other parts of the loops. In the experiment of current distribution between two X-pinches, the current flowing through the two X-pinches does not depend on the diameter or material of the X-pinch, confirming that current division has something to do with the parts of the parallel circuits other than X-pinches. The amplitude of current flowing in the X-pinch farther from the polyformaldehyde isolation rod is always slightly higher than the other, indicating the influence of the mutual inductance between the branch circuits.
