Question

A metal wire is subjected to a constant potential difference. When the temperature of the metal wire increases, the drift velocity of the electron in it ______.

Options

• increases, thermal velocity of the electron increases
• decreases, thermal velocity of the electron increases
• increases, thermal velocity of the electron decreases
• decreases, thermal velocity of the electron decreases

Answer 1

A metal wire is subjected to a constant potential difference. When the temperature of the metal wire increases, the drift velocity of the electron in it decreases, thermal velocity of the electron increases.
