Vedclass · Answer

(D) The heat produced $(H)$ in a resistor of resistance $R$ due to a current $i$ flowing for time $t$ is given by Joule's law of heating: $H = i^2Rt$.Assuming resistance $R$ and time $t$ are constant,we have $H \propto i^2$.This equation represents a parabola opening upwards along the $H$-axis (or $U$-axis in this graph).Looking at the provided curves,curve $d$ represents a parabolic relationship where $H$ increases more rapidly as $i$ increases,which is characteristic of a quadratic dependence $(i^2)$.Therefore,curve $d$ is the correct representation.

Which of the following curves represents the relationship between the heat produced in a resistor and the current flowing through it?
