Heat Transfer

Q1: Heat flux through several resistances in series in analogous to the current flowing through several

A resistances in parallel.

B capacitors in series.

C resistances in series.

D none of these.

ANS:C - resistances in series.

Heat flux through several resistances in series is analogous to the current flowing through several resistances in series, not in parallel, capacitors in series, or none of these. In both cases, when resistances are in series, the overall resistance increases, leading to a decrease in the flow rate. Similarly, when heat flows through several resistances in series, the overall heat flux decreases, as the total resistance to heat flow increases. Therefore, the correct analogy is resistances in series.
