Problem

Two resistors of 2 Ω2\,\Omega and 8 Ω8\,\Omega are connected in series to a constant-voltage battery. Answer the questions below without substituting numerical values for the voltage. (i) Which of the two resistors will dissipate more power? State your choice clearly. (ii) Justify your answer in part (i) by comparing the powers developed in the two resistors. Show all necessary reasoning. (iii) Explain, in terms of heating effect, which resistor is more likely to become hotter and why.
