By use of the multiple Josephson junction model, we investigate voltage-biased I-(Formula presented) characteristics by numerical simulation. We show that there exist three characteristic regions in the (Formula presented) 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-(Formula presented) characteristics form a multiple branch structure as in the current-biased case.
