Question

The velocity of charge carriers of current (about 1 ampere) in a metal under normal conditions is of the order of

• A. a fraction of mm/sec
• B. velocity of light
• C. several thousand metres/second
• D. a few hundred metres per second

Answer 1

Answer: (A)

a fraction of mm/sec

Answer 2

The velocity of charge carriers of current (about 1 ampere) in a metal under normal conditions is of the order of a fraction of $mm / \sec$.
So, the correct answer is (A): of a fraction of $mm / \sec$
