Apparently not. They don't drop to the ground dead while sitting on the wire, but
are able to primp, preen, look around, and leave the wire when they feel like it.
Not so. We see birds sitting on active high lines all the time.
Because you're standing on the ground. But the bird contacts only the wire, sothere's no path through the bird for current to flow from the wire to anywhere else.
The voltage applied to the corona wire in a xerographic copier or printer varies depending on the manufacturer and model, however, it is a high voltage. On the other hand, that voltage is applied but is not emitted. It is a static electrical voltage and does not go anywhere (there is no effective current)
yeeee :)
That will induce a voltage across the wire.
If you got shocked by any type of electrical current it would certainly knock you off the wire .
As shocked as a bird landing on live wire. :)
The wires are coated in rubber.
Not so. We see birds sitting on active high lines all the time.
To get electric shock, the circuit must be completed and the subject who is in the path, or who becomes the path gets shock. When a bird sits on the wire, there is no closed path or circuit hence it does not shock. Same bird while sitting on the wire, and part of its body touches the earth or ground it then will get shock.
An animal such as a bird or rodent sitting on a "high tension wire" (electrical line) will not be shocked because it is not connected to a lower voltage, or ground. In order for electricity to flow there must be a difference in potential. (The scenes in movies where people fry when they are suspended in the air on high voltage grids are not in accordance with the laws of science-just as Superman could not really stop a speeding bullet or falling meteor.) If you-- a person-- touch the same wire while standing on the ground your body WILL provde a means of current flow as you are conectged to "ground"--which, by definition is low or no voltage. but if you are ONLY on the wire, and not the ground, same result. No current flow.

In order for electricity to shock something it needs to be touching the ground. Electricity goes through the body and back into the ground. Since the crow is in no way touching the ground the electricity has no where to go and thus can not shock the crow. If you touch the wire and are not touching anything that conducts electricity (like metal) and are not touching the ground you will not get shocked either. But if you stand on the ground and touch the wire you will get shocked.
As long as there is no path to earth both the bird and the man won't get shocked.
If they are grounded they get an electric shock or electrocuted. If they are not grounded or in simultaneous contact with the neutral wire, nothing. That's why birds can sit on a high voltage wire and survive; they are not grounded.
Need more information. Wattage of bulb, voltage of bulb, voltage of battery and wire size of the circuit.
yes, all conductors shall be insulated to the highest voltage utilised
