Whoaaaa... whacking a power line with a metal net could cause instant death, even if the rod holding the net is non-metal, for it still will have some conducting properties, and allow current to flow through you to the ground. Shoot 170 milliamps through your herat and we'll see you in the next world. Most powerline wires are NOT insulated ...the wire is bare...or the insulation, IF present, is intended only for preventing short circuits due to occasional short duration contacts of small tree branches, and has perhaps only a 600 volt rating. NEVER touch a powerline with ANYTHING.DaveC426913 said:

I don't see anything wrong with it. The current passing through the bird over that short distance of 'voltage drop' with very low potential difference, coupled with the very low resistance of the wire (something like in the order of one-thousandth of an ohm per foot...I'd have to look it up) would be very low...maybe less than a milliamp or so...an imperceptible and non-deadly current (the 'let-go' current of an adult male human..where the muscles 'freeze'...is about 9 milliamps or so, less for a woman or child (5 or 6 milliamps). But don't assume any insulation on the wires..if they were fully insulated for the applicable phase to ground voltage, that would sure change the picture for the better...but most powerlines use bare wires, at least the high voltage ones.pivoxa15 said:
The reason birds don't get electrocuted when they sit on power lines is because they are not grounded. Power lines are designed to carry electricity at a high voltage but with low current. Since birds are not touching the ground or any other conductive material, the electricity cannot flow through their bodies and they remain unharmed.
Yes, it is possible for birds to get electrocuted if they touch both a power line and a tree branch at the same time. This creates a path for electricity to flow through their bodies and can result in injury or death. However, birds have an instinctual understanding of electricity and can usually avoid this type of dangerous situation.
Birds do not have a specific resistance to electricity, but their body composition and size can play a role in their ability to withstand an electric shock. Larger birds, such as eagles, have a higher chance of surviving an electric shock compared to smaller birds like sparrows due to their size and muscle mass.
No, birds are not immune to electricity. In fact, birds can be injured or killed by electricity if they come into contact with high enough voltage or current. However, their survival rate is generally higher compared to other animals due to their unique physiology and behavior around electricity.
While it is rare, there have been documented cases of birds being electrocuted on power lines. This is often due to factors such as wet feathers, a damaged power line, or a bird's inexperience with electricity. Additionally, certain bird species, such as water birds, are more susceptible to electrocution due to their habitat and behavior.
