Question 187: Current Electricity

Question

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

Accepted Answer

$H \propto i^{2}$ for $t=$ constant
$$ \Rightarrow $$ $$
\frac{H}{H^{\prime}}=\left(\frac{4}{16}\right)^{2}
$$
$$ \Rightarrow $$ $H^{\prime}=16 H$

Answer

$\frac{\mathrm{H}}{4}$

Answer

$16 \mathrm{H}$

Answer

H

Answer

$4 \mathrm{H}$
