The immediate pulse (first ~100ns) has the same "very slight lift" visible in AlphaPhoenix's result. Also the simulation replicates his lower than expected DC return (first ~100ns) to some extent. If you curve fit the blue line up a little higher, that effect is even stronger. |

If COMSOL change the resistance of the bulb to 718 Ohm then half the battery voltage will appear across the bulb after 3.3 ns. |

Transmission line theory cannot be used to model the initial 1m/c delay. I mentioned this in my previous posts. --- End quote --- We both know they do not match. I just wanted to see if you can show just the first ten nanoseconds to see how much they do not match. (This, as well has been debated in previous posts - but it would be nice to see it graphically) |
