A bird sitting on a high tension electric wire does not get electrocuted because:
Correct answer: C. it does not form a closed path for the flow of current
- A. Sit has high resistance
- B. the body is earthed
- C. it does not form a closed path for the flow of current
- D. its feet are good insulators
Explanation
A bird on a single wire has both feet nearly at the same electrical potential, so there is no significant voltage across its body to drive current. Merely touching a high-voltage wire is dangerous when another contact provides a potential difference.
