This question is difficult to answer If we talk about single streamers, then the resistance is 500 kOhm for a 10 cm long streamer. Approximately the same resistance has a 5 cm long streamer. If you are interested in this question in more detail, then you can find the answers in our article PROBE MEASUREMENTS OF PARAMETERS OF STREAMERS OF NANOSECOND FREQUENCY CROWN DISCHARGE
