By use of the multiple Josephson junction model, we investigate voltage-biased I-V characteristics by numerical simulation. We show that there exist three characteristic regions in the I-V curve. In the low voltage region, the total current is periodic with trigonometric functional increases and rapid drops. Then a kind of chaotic region follows. Above a certain voltage, the total current behaves with a simple harmonic oscillation and the I-V characteristics form a multiple branch structure as in the current-biased case.
