MCQ
A bird sitting on a single high tension wire does not get electrocuted because
  • A
    the circuit is not complete
  • B
    resistance of the bird is too high
  • C
    capacitance of the bird is too small and the line frequency is too small
  • Both $a$ and $b$

Answer

Correct option: D.
Both $a$ and $b$
d
(d)

When bird sits over a high tension wire, its both feet are nearly at same potential. So, no current flows through bird's body.
