Multiple choice

Directions: The following question consists of two statements, one labelled as 'Assertion' and the other labelled as 'Reason'. Assertion: A bird sitting on 11, 000 V wire is quite safe but a man touching 220 V wire may die. Reason: The potential difference exists between the two as the earth is at different potential.

Select your answer to this question using the codes given below.

  1. If both assertion and reason are true and statement 2 is the correct explanation for statement 1

  2. If both assertion and reason are true but statement 2 is not the correct explanation for statement 1.

A Correct answer
Explanation

Death may be caused if a heavy current flows through the body. The current flows due to potential difference. When a person standing on earth touches a 220V line, potential difference exists between the two as the earth is at different potential. However, a bird is at 11,000 V potential but no current flows through it because there is no potential difference across its body.
