Question

Birds do not get electric shocks even if they are on a high voltage wire because:

• A. They have high resistance in their body.
• B. There is zero potential difference between any two points in their body
• C. Their body parts are made of insulators.
• D. Inside of their bodies there are very high voltages.

Answer 1

The correct option is B There is zero potential difference between any two points in their body

Birds usually stand on single live wire and so electric current doesn't flow through the bird .When a bird stands on a high voltage wire, there is no potential difference between the legs of the bird as it stands in a single wire and hence no current passes through it.
