Rebalance of superconducting tapes in parallel connection

The objective of this paper is to reveal the current distribution in parallel superconducting tapes with different lengths. A 10 cm tape and a 15 cm tape are connected in parallel. Their voltage drops and current distributions are measured. The limited current in the 15 cm tape is I₁ and the limited current in the 10 cm tape is I₂. The result of I₁ / I₂ is 0.77 in the experiment. The result of I₁ / I₂ in the simulation is 0.80, which supports the experiment result. The I₁ / I₂ ratio of 0.77 reveals a more evenly current distribution than the ratio of 0.67 shared by two resistors connected in parallel with a length of 15 cm and a length of 10 cm. The current in parallel superconducting tapes tends to rebalance in this imbalance situation.
