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

The charge flowing through a resistance $R$ varies with time according to $Q = at - bt^2$. The total heat produced in $R$ is: (assume that the direction of current is not reversed)

One junction of a certain thermoelectric couple is at a fixed temperature $T_r$ and the other junction is at temperature $T$. The thermo-electromotive force for this is expressed by $E=k(T-T_r)[T_0-\frac{1}{2}(T+T_r)]$. At temperature $T=\frac{1}{2} T_0$,the thermoelectric power is

The dimensions of $CV^2$ match with the dimensions of:

Consider the four circuits shown below. In which circuit is the power dissipated the maximum? (Neglect the internal resistance of the applied power source $E$)

The temperature of the cold junction and the neutral temperature of a thermocouple are $15\,^{\circ}C$ and $280\,^{\circ}C$ respectively. The temperature of inversion is .............. $^{\circ}C$.
