The bird perching on a high-power line does not get electroshock. This is because.
Correct answer: A. The whole body of the bird sitting on the live wire is at the same potential and hence no current flows through the body
- A. The whole body of the bird sitting on the live wire is at the same potential and hence no current flows through the body
- B. The whole body of the bird sitting on the live wire is at zero potential and hence no current flows through the body
- C. Because the air medium between the live wire and the earth contains large numbers of charged particles
- D. Because the air medium between the live wire and the earth contains large number of electrons
Explanation
The whole body of the bird sitting on the live wire is at the same potential and hence no current flows through the body.When a bird perches on a high-power line, its entire body is at the same electric potential as the wire. Since there is no potential difference between different parts of the bird's body, no electric current flows through it. This is because electric current requires a potential difference (voltage) to drive it, and in this case, there is no voltage across the bird's body

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
