Question

The quantity of heat generated in a conductor depends on _____.

• A. square of the current $\left(I^2\right)$
• B. resistance of the conductor $\left(R\right)$
• C. time for which the mean flows $\left(t\right)$
• D. $I^{2}Rt$.

Answer 1

Answer: (D)

$I^{2}Rt$.

The quantity of heat generated in a conductor depends on square of the current $\left(I^2\right)$. Now, according to Joule's law,

$H=I^{2}Rt$

where $H=$ heat

$I=$ current

$R=$ resistance

$t=$ time taken
