Why dont birds get electocuted when they are on power lines?

    Maybe because charge passes through the powerlines and doesnt stay at one spot?

    How are power transmission lines physically arranged? How many wires are there, and how far apart are they spaced? What are the typical AC voltages involved, and how are the voltages distributed between the wires? Why are the wires in the AC transmission lines spaced apart like that?

    No... the circuit isnt complete. There is no potential difference. If, however, a man standing on the ground touched the same wires, he would be electrocuted, as the potential on the ground is zero and a potential difference existas across the man.
