Oh...so let's say that a current pulse for 200 microseconds existed...could we take it that inductance is negligible? The problem I was doing involved a partial branch of a circuit with a .01H inductor parallel to a 100 Ohm resistor. It stated that a current pulse existed, in which it jumped from 0 to 10 Amps, stays for 200 microseconds, then drops to 0A (these values are for the current before the junction). The problem asked me to come up with a function of time for the current through the inductor for that period of 200 microseconds, but to come up with the answer they gave, we have to assume that the current before the junction is unaffected by the inductor (remains 10A for that period)...also, the rate at which the current jumps and drops is almost a straight vertical line...it was as if the phenomenon of inductance was completely neglected; so I was assuming this might be a little different from simply closing a DC circuit for 200 microseconds.
