Question

Which of the following statement is false

• A. Heat produced in a conductor is proportional to its resistance
• B. Heat produced in a conductor is proportional to the square of the current
• C. Heat produced in a conductor is proportional to charge
• D. Heat produced in a conductor is proportional to the time for which current is passed

Answer 1

Answer: (C)

Heat produced in a conductor is proportional to charge

Answer 2

$H = i^{2}Rt$ and $i = \frac{q}{t}$. Hence $H = \frac{q^{2}R}{t};\therefore H \propto q^{2}$
