Question

The $H$ amount of thermal energy is developed by a resistor in $10 s$ when a current of $4 A$ is passed through it If the current is increased to $16 A$, the themal energy developed by the resistor in $10 s$ will be:

• A. $\frac{ H }{4}$
• B. H
• C. $4 H$
• D. $16 H$

Answer 1

Answer: (D)

$16 H$

Answer 2

$H∝ i^2$ for t = constant
$\frac{H}{H'} = (\frac{4}{16})^2$
$H'= 16\,H$
So, The Correct answer is option (D): 16H
