Re: Question in the electrification

Do the links not work for you?

Q1.
Birds (a) don't conduct well and (b) they don't touch the ground while touching the wire.

Q2.
Quote:
 Body resistance The voltage necessary for electrocution depends on the current through the body and the duration of the current. Ohm's law states that the current drawn depends on the resistance of the body. The resistance of human skin varies from person to person and fluctuates between different times of day. The NIOSH states "Under dry conditions, the resistance offered by the human body may be as high as 100,000 Ohms. Wet or broken skin may drop the body's resistance to 1,000 Ohms," adding that "high-voltage electrical energy quickly breaks down human skin, reducing the human body's resistance to 500 Ohms."

It depends on the voltage and the fat content of the person.
