The total power dissipated in the circuit shown here is ............. $W$.

The Thomson coefficient of a conductor is $10\,\mu V/K$. The two ends of the conductor are maintained at $50\,^{\circ}C$ and $60\,^{\circ}C$ respectively. The amount of heat absorbed by the conductor when a charge of $10\,C$ flows through it is:

For ensuring the dissipation of the same energy in all three resistors $({R_1}, {R_2}, {R_3})$ connected as shown in the figure,their values must be related as:

$A$ cell having an emf $\varepsilon$ and internal resistance $r$ is connected across a variable external resistance $R$. As the resistance $R$ is increased,the plot of potential difference $V$ across $R$ is given by:

Which of the following circuits follows Ohm's law?

The temperature coefficient of resistance of tungsten is $4.5 \times 10^{-3} \, ^{\circ}C^{-1}$ and that of germanium is $-5 \times 10^{-2} \, ^{\circ}C^{-1}$. $A$ tungsten wire of resistance $100 \, \Omega$ is connected in series with a germanium wire of resistance $R$. The value of $R$ for which the resistance of the combination does not change with temperature is .......... $\Omega$.
