    He probably wanted to prevent significant arcing by using a higher impedance test apparatus due to the high voltage.

    Even throwing a metal pipe against it won’t do anything. Electric fences have one electrode in the ground, and that’s how your body makes the circuit. If they had run and jumped onto the fence, then jumped off on the other side they would have been fine with the fences still active.

    Source: I’ve set up an electric fence and been shocked multiple times, once through my head.

      Yet Tim gets shocked when hanging on the fence when it turns on while he’s climbing down. I trust movie science far more than your acquired knowledge. Your ignorance is probably what’s holding you back from full blown deity.

      You’re assuming the dinosaur fence operates on the same principal as a regular livestock electric fence. I put it to you that the Dino enclosures use alternating positive and negative stringer wires, where touching one won’t do anything, but touching two will make a short circuit.

        That would make a lot of sense, but as we can see the stringers are connected together, meaning they’d just short out if they were alternate polarities. To me this indicates that it’s like a standard livestock fence, with an electrode in the ground somewhere and the circuit completing through the animal.

        However, considering my 16’x48’ pig enclosure required a three-foot rod to be grounded, a system large enough for a sauropod would need a lot of grounding. Considering this, the fact that they used a circuit-through-animal design indicates it probably wasn’t the best way to do it.

        Spared no expense…

          Maybe the stringer spacers are polymer though. Like those separation bars you see on residential power lines

            Maybe they’re polymer but they look pretty metallic and there’s an awful lot of them. Plus if the stringers are under enough tension for a full grown man to climb them they wouldn’t need separators.

      uhm, I’ve seen (touched, oops) electric fences (low power tho) with both conductors in the wire, uncovered but not touching.

    He is already standing too close and that stick would arc with that many volts flowing through it. The most likely outcome in reality if it had been energized. The arc would have jumped from the stick to him and no more New Zealand guy.

      With only 10’000 V? That’s a common Livestock Guardian*. Reaches at most 1 cm.

      * though it probably has enough ampere to kill a cow

        Now if he’d just tossed the stick at it longwise so that it touched several wires at the same time, it might get a result. I’m personally not sure how much a reaction you’d get out of dry wood with 10,000 volts. Stripping the bark off of green stick with definitely be better, or a wet stick. Although if electricity arced through the stick at least it probably wouldn’t kill him because of the amount of resistance that stick has.

        You ever saw a electric fence at a high security installation? I just texted a guard at nearby prison and he said theirs are 5000 volts. He said when its humid they tingle when you get a few feet away. He also says they will kill you dead. He goes on to say its why they have another fence as a barrier to prevent people who don’t respect them from killing themselves. I know the ones at a nuke were marked lethal and would kill birds from time to time. They were just marked high voltage but the plant guys told us they were very high voltage at a higher frequency.

          Yep, Volt makes sparks, Ampere makes hurt.

          Tesla coils usuallly have around 100k Volt and don’t kill you. Tasers 20k to 40k i think? The high voltage in guardians is mostly so that it connects.

      The first film paints a different picture.

      The whole point of his story in that film was his growth and development, started saying “kids smell” and ended holding two of them safe.

      He was the one throughout who kept his head, stayed competent in the face of fear and dealing with chaos.

        Characters in Jurassic Park are portrayed as flawed, imperfect people who make mistakes. None of the plot relies on them being idiots or anything, but people screw up, panic on occasion, and don’t know things from time to time.

        Dr. Grant using a stick to test the fence is a mistake, albeit a small one without real consequences. While it doesn’t distract from his character arc of how he feels about kids, it is his character simply messing up.

        I also disagree with the person you replied to. While their assessment is correct, Dr. Grant is a character with a lot of time working in the field and therefore has a lot of practical skills. He does way, way better than a doctorate in mathematics working in academia would. Writing off all people with a doctorate (or experts in general) as being hyper specialized is a mistake.

    IIRC, he was messing with the kids and knew it was off because the lights were off. He proceeded to put his hands on it and convulse wildly as a joke.

      He was messing with the kids when he grabbed the wires, not when he threw the stick.

        I always saw it as being part of messing with the kids, he looks at the warning lights on top of the fence first. And for my headcannon at least, Grant is savvy enough to know that’s no way to test if the fence is live or not, lol.
