Main Question or Discussion Point
If you leaped onto an electric fence would I be right in assuming you wouldn't get electrocuted as long as you don't provide a path for the charge to neutralize itself?
I did not say mutual capacitance with ground or the return wire, I said body capacitance. The usual human body model is capacitance of about 100 pF (a good match to the the self capacitance of a 90 cm sphere, though likely derived from actual measurements, or at least a more detailed model) in series with a 1.5 kohm resistance. The exact value will indeed depend on the situation, but birds have far more capacitance simply due to being smaller...that they perch on the wire and feel nothing is no guarantee that you would feel nothing if you did the same.humans have considerably more body capacitance than birds...roughly 100 pF
A human body is effectively a conductor, so this might act as one plate of a capacitor. The dielectric may be air or a pair of insulated boots and the other plate may be the ground or the return wire of the electric fence.
It is not reasonable to claim a person would have 100 pF to ground unless you knew the exact situation
Depending on the fence, you could also weigh wires down or otherwise push them apart with something, either a good insulator or taking care not to touch the object while it's in contact with the fence. Or push one of the neutral wires aside and squeeze through. Or just brave the shocks and go through/over...depending on the charger, you could have a decent chance of getting through between pulses, and if you get hit, we're talking about a mildly unpleasant experience, especially if you're poorly grounded. I wouldn't try this with a fence meant to deter humans, though.As the fence will not be monitored (I assume) you could just Earth it to a stake in the ground, temporarily, then pull out the stake when you're over / through it. That's the Engineer's solution - not the Physicist's.
Or you could wear a Faraday Suit or learn to pole vault.
Oops...yes. Or as I put it the first time, that humans have more.btw, cjameshuff, don't you mean that birds would have lower capacitance?
